-	* avr.c, config_gram.y, lexer.l, term.c:
-	In interactive mode, reset the address and length if we start dumping
-	a memory type different than the previous one.
-
-	* avr.c, avrdude.conf.sample, config_gram.y:
-	Allow instruction data to be specified more flexibly, which can be
-	used to make the instruction input more readable in the config file.
-
-	* main.c: Bump version number.
-
-	* Makefile, avr.c, avr.h, avrdude.conf.sample, config.c, config.h:
-	* config_gram.y, fileio.c, fileio.h, lexer.l, main.c, term.c:
-	This is a major re-write of the programming algorithms.  The Atmel
-	serial programming instructions are not very orthoganal, i.e., the
-	"read fuse bits" instruction on an ATMega103 is an entirely different
-	opcode and data format from the _same_ instruction for an ATMega163!
-	Thus, it becomes impossible to have a single instruction encoding
-	(varying the data) across the chip lines.
-
-	This set of changes allows and requires instruction encodings to be
-	defined on a per-part basis within the configuration file.  Hopefully
-	I've defined the encoding scheme in a general enough way so it is
-	useful in describing the instruction formats for yet-to-be invented
-	Atmel chips.  I've tried hard to make it match very closely with the
-	specification in Atmel's data sheets for their parts.  It's a little
-	more verbose than what I initially hoped for, but I've tried to keep
-	it as concise as I could, while still remaining reasonably flexible.

-2001-11-19  Brian S. Dean  <bsd@bsdhome.com>
-
-	* avr.c, avr.h, avrdude.conf.sample, main.c, ppi.c, term.c:
-	Add support for ATMega163.
-
-	Add support for reading/writing ATMega163 lock and fuse bits.
-	Unfortunately, in looking at the specs for other ATMega parts, they
-	use entirely different instruction formats for these commands.  Thus,
-	these routines won't work for the ATMega103, for example.
-
-	Add support for sending raw command bytes via the interactive terminal
-	interface.  This allows one to execute any programming instruction on
-	the target device, whether or not avrprog supports it explicitly or
-	not.  Thus, one can use this feature to program fuse / lock bits, or
-	access any other feature of a current or future device that avrprog
-	does not know how to do.
-
-	Add in comments, an experimental instruction format in the
-	configuration file.  If this works out, it would allow supporting new
-	parts and non-orthoganal instructions across existing parts without
-	making avrprog code changes.

-
-	* main.c: Version 1.1
-
-	* main.c:
-	Hmmm ... cvs co -D <timestamp> does not work.  Change the revision
-	timestamp to a full date/time value.
-
-	* avr.c, fileio.c, main.c, ppi.c, term.c:
-	Add a -V option to display the version information about each
-	component module.  This is intended for support purposes, so that I
-	can tell unambiguously what version a binary out in the field is.
-
-	Additionally, display a revision timestamp along with the version
-	number.  This also is intended for aiding in support and is the Unix
-	time of the latest component module.  Having this, should allow me to
-	do a "cvs co -D timestamp avrprog" and get exactly the source of the
-	version that is being reported.
-
-	* fileio.c:
-	Return the maximum address (+1) written as opposed to the actual
-	number of bytes written.  The presence of an Intel Hex address
-	record can cause these two number to be different; but the callers
-	of this routine need the former.
-
-	* main.c:
-	Fix a place where we were exiting without applying the exit-specs.
-
-	Wrap a long line.
-
-	* avr.c, fileio.c: avr.c: Update a comment.
-
-	fileio.c: Properly handle all the Intel Hex record types that I can
-	          find information about.

-	* Usage, avr.h: Get rid of the Usage file.
-
-2001-01-24  Brian S. Dean  <bsd@bsdhome.com>
-
-	* Makefile, avr.c, avr.h, main.c, pindefs.h, ppi.c:
-	Move pin definitions to their own file.
-
-	First pass at providing feedback via the optionally connected leds.  I
-	don't actually have any of these attached to my programmer, so I can
-	only guess as whether this is toggling them on and off correctly.
-
-	Also, enable and disable the optional 74367 buffer.
-
-	* avr.h, main.c, ppi.c, ppi.h, avr.c:
-	Rearrange the pinout for the programmer to be a little more logical.
-	Provide hooks to support a buffered programmer, pin 6 is now used to
-	enable a buffer that can be used to isolate the target system from the
-	parallel port pins.  This is important when programming the target
-	in-system.
-
-	Totally change the way the pin definitions are defined.  Actually
-	set/clear pins based on the way more intuitive pin number, instead of
-	PPI data register, bit number combination.  A table of pin data is
-	used so that any hardware inversion done by the parallel port is
-	accounted for, what you set is actually what appears at the pin.
-	Retain the old method for handling Vcc, however, because the hold
-	method is much easier to use when setting / retrieving multiple pins
-	simultaneously.
-
-2001-01-22  Brian S. Dean  <bsd@bsdhome.com>
-
-	* Makefile: Don't gzip the man page.
-
-	* avrdude.1: .Nm macro fix.  Submitted by Joerg.
-
-	* main.c: Cosmetic, don't output a preceding linefeed for usage().
-
-	* Makefile, avr.c, avr.h, fileio.c, term.c:
-	Makefile : use gzip -f for man page installation so that we don't get
-	           prompted.
-
-	avr.c avr.h fileio.c term.c :
-
-	     Change the avrpart data structure so that the typedef AVRMEM is
-	     used as an index into an array for the sizes of the memory types
-	     and also for pointers to buffers that represent the chip data for
-	     that memory type.  This removes a lot of conditional code of the
-	     form:
-
-			switch (memtype) {
-				case AVR_FLASH :
-			 	...
-			}
-
-	     Also, re-code avr_read_byte() and avr_write_byte() to properly
-	     handle the flash memory type without having to tell them whether
-	     they should program the high byte or the low byte - figure that
-	     out from the address itself.  For flash memory type, these
-	     routines now take the actual byte address instead of the word
-	     address.  This _greatly_ simplifies many otherwise simple
-	     operations, such a reading or writing a range of memory, by not
-	     having to worry about whether the address starts on an odd byte
-	     or an even byte.
-
-2001-01-20  Brian S. Dean  <bsd@bsdhome.com>
-
-	* avr.c, avr.h, fileio.c, fileio.h, main.c:
-	Return error codes instead of exiting, thus making sure that we exit
-	only via main() so that the exitspecs are properly applied.
-
-	When reading input data from a file, remember how many bytes were read
-	and write and verify only that many bytes.
-
-	Don't complain when an input file size is smaller than the memory size
-	we are programming.  This is normal.
-
-	* fileio.c:
-	Correct checksum calculation; failure to account for the value of the
-	record type was causing non-zero record types to be calculated
-	incorrectly.
-
-	* Makefile, main.c: Makefile : install the man page
-
-	main.c : drop the giant usage text now that we have a man page.
-
-	* avrdude.1:
-	Add initial man page graciously contributed by Joerg Wunsch.  Thanks
-	Joerg!
-
-2001-01-19  Brian S. Dean  <bsd@bsdhome.com>
-
-	* term.c:
-	Accept abbreviations for eeprom and flash for the dump and write
-	commands.
-
-	Fix small bug keeping 1 character command lines from being added to
-	the history.
-
-	* term.c:
-	Implement enough state in cmd_dump so that if it is called with no
-	arguments, it successively dumps the next chunk of data of the same
-	previously specified length.
-
-	* term.c, term.h, fileio.c, fileio.h, main.c, ppi.c, ppi.h:
-	* Makefile, avr.c, avr.h, avrprog.c:
-	The program was getting too large for a single file.  Split it up into
-	more modular pieces.
-
-	Also, accept command abbreviations as long as they are not ambiguous.
-
-	* avrprog.c:
-	Add ability to specify the state of the power and reset pins on
-	program exit.  Default to leaving the pins in the state they were when
-	we found them.

-
-	* Makefile, avrprog.c:
-	Switch to using readline() for getting terminal input.  I can't seem
-	to get the history capabilities working yet, but even so, it does
-	better handling of the prompt and strips newlines for us, so it's
-	still a win.
-
-	Add a few new commands for terminal mode: help, sig, part, erase.
-	Display rudimentory help using the help command.
-
-	Add some function prototypes.
-
-	* Usage, avrprog.c:

-
-	Fix a few "may be used uninitialized" bugs found by -Wall.
-
-2001-01-14  Brian S. Dean  <bsd@bsdhome.com>
-
-	* avrprog.c: Free a buffer.
-
-	* avrprog.c:
-	Use a smarter programming algorithm - read the existing data byte
-	first and only write the new one if it is different.
-
-	Add -n option which is a test mode in which the chip is not actually
-	updated.  This option does not affect writes in interactive mode.
-
-	* avrprog.c: Add the "dump" and "write" interactive commands.
-
-	* avrprog.c:
-	Correctly produce and handle "end of record" for intel hex files.
-
-2001-01-13  Brian S. Dean  <bsd@bsdhome.com>
-

-	instead of hard-coded values for the 2313.
-
-	* avrprog.c: Fix filename assignment error.
-
-	Clean up debugging code a little, utilize fileio() instead of making
-	direct calls to b2ihex().
-
-	* avrprog.c: A lot of general code cleanup.
-
-	Re-work command line options to be more intuitive.
-
-	Support Intel Hex input and output file formats.  Provide hooks to
-	support Motorola S-Record as well.
-
-	Add a few more part-specific parameters to the avrpart structure.
-
-	Only write the flash or eeprom if the data to be written is not 0xff.

-	term.c - when in interactive terminal mode and dumping memory using

-
-	CHANGELOG - describe changes
-
-	main.c - update version number
-
-	* main.c:
-	When getting ready to initiate communications with the AVR device,
-	first pull /RESET low for a short period of time before enabling the
-	buffer chip.  This sequence allows the AVR to be reset before the

-	* avr.c, term.c:
-	Use a four byte value instead of a two byte value for the programming
-	cycle count stored at the end of EEPROM.  It seems as though Atmel was
-	greatly conservative in claiming a 1000 count reliability for the

-	* avr.c: If a memory region has a page size declared, try
-	using the paged IO routines regardless of the target memory
-	name.  Xmega EEPROM requires to be written in paged mode.
-	Correctly use a long (rather than unsigned long) variable to
-	evaluate the success status of the paged mode write attempt.
-	* stk500v2.c: Don't apply TIF space offsets twice (bug #27995:
-	AVRDUDE 5.8svn fails to program and read XMEGA); use
-	stk500v2_loadaddr() prior to paged mode (EEPROM and flash) writes,

-	check the return value of stk500v2_loadaddr() everywhere; use the

-	* jtagmkII_private.h: Add CMND_XMEGA_ERASE as well as
-	the various XMEGA_ERASE_* definitions (from updated
-	appnote AVR067)
-	* jtagmkII.c (jtagmkII_chip_erase): Correctly implement Xmega chip
-	erase based on CMND_XMEGA_ERASE.  After erasing an Xmega part, do
-	*not* reinitialize the world, as a subsequent programming
-	operation will fail (for unknown reasons).  Actually, this was
-	really only required for ancient AVRs, but doesn't hurt on mega
-	and tiny devices.
-	* jtagmkII.c (jtagmkII_pre_write): Remove, this turned out
-	to be just a chip erase.
-	* jtagmkII.c (jtagmkII_program_disable): Don't try reading
-	"hfuse" for Xmega parts; they don't have it.
-	* main.c (main): Re-enable auto-erase.  It's been done
-	before (as "jtagmkII_pre_write") in jtagmkII_paged_write()
-	anyway.  Xmega boot and application flash areas should be
-	handled separately in the future, so auto_erase can only
-	affect the area just being programmed.

-	bug #34518: loading intel hex files > 64k using record-type 4
-	(Extended Linear Address Record)
-	fileio.c: Replace the change from r928 (handling of 0x8000000
-	offset in AVR32 files) by a completely different logic that no
-	longer breaks hex files for other devices starting with an
-	offset; also apply a similar change to S-record files, as well
-	as when writing files.

-2011-09-15  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* stk500v2.c (stk600_xprog_paged_load, stk600_xprog_paged_write):
-	Fix regression in the AVRISPmkII/STK600 TPI handling introduced
-	by the USBasp's TPI implementation which added a pagesize even for
-	the minor memory regions of TPI devices.  Also fix wrong offset
-	introduced by the memory tagging patch.
-
-2011-09-15  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* avr.c (avr_read, avr_write): Don't bail out on TPI parts if
-	their programmer doesn't provide a (low-level) cmd_tpi method;
-	instead, fall back to the normal programmer methods which are
-	supposed to handle the situation.
-	This fixes a regression where the recent bitbang-TPI implementation
-	broke TPI handling of STK600/AVRISPmkII.
-
-2011-09-14  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	Mega-commit to bring in memory tagging.
-	Each memory image byte is now tagged as it's being read from a file.
-	Only bytes read from a file will be written or verified (modulo page
-	granularity requirements).
-	* avrpart.h: Add memory tags.
-	* avrpart.c: Allocate and initialize tag area.
-	* update.h: Drop unused parameter "verify" from do_op().
-	* pgm.h: Add parameter base_addr to the paged_load and paged_write
-	methods, respectively.
-	* avr.h: New parameter to avr_read: second AVRPART to verify against.
-	* fileio.c: Track all memory regions that have been read from an
-	input file by tagging them.
-	* update.c: Call avr_read() with the new parameter list.
-	* main.c: Call avr_initmem() to initialize the memory regions, rather
-	than trying to duplicate an unitialized part, and then let the
-	original part rot away.
-	* avr.c: Implement the heart of the new featureset.  For paged memory
-	areas, when writing or verifying, call the paged_write and paged_load
-	methods, respectively, once per page instead of on the entire memory.
-	When writing, only write bytes or pages that have content read from a
-	file.  Whe verifying, only read memory bytes or pages where the
-	verification data have been read from a file.  Only verify those bytes
-	that have been read from a file.
-	* avrftdi.c: Implement the new API for paged_load and paged_write,
-	respectively.
-	* jtagmkII.c: (Ditto.)
-	* butterfly.c: (Ditto.)

-
-	bug #34027: avrdude AT90S1200 Problem (part 2 - stk500v2 and relatives)
-	* stk500v2.c (stk500v2_initialize): For the AT90S1200, release
-	/RESET for a moment before reinitializing, as this is required by
-	its programming protocol.
-
-2011-08-30  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* configure.ac: In AC_CHECK_LIB for libftdi, check for
-	ftdi_usb_get_strings() rathern than ftdi_init(), as this is a more

-	recent enough libftdi.

-	* bitbang.c (bitbang_initialize): Replace existing test for
-	AT90S1200 by AVRPART_IS_AT90S1200
-	* avr.c (avr_write_byte_default): Avoid the pre-write reading for
-	the AT90S1200, as this appears to sometimes corrupt the high byte
-	by pre-programming the low byte just written into it.

-
-2012-07-29  Hannes Weisbach <hannes_weisbach@gmx.net>
-
-	* avrftdi.c: bugfixes (synchronisation) and maintenance (paged programming,
-	nicer output, separation of parameter checking and actual code)
-
-2012-07-25  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* jtagmkII.c (jtagmkII_memtype): return MTYPE_FLASH rather than
-	MTYPE_SPM for non-Xmega flash regions
-
-2012-07-20 Hannes Weisbach <hannes_weisbach@gmx.net>
-
-	* avrpart.c, avrpart.h: adds avr_pin_name()
-
-2012-07-18  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-

-
-2012-06-07  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* usbtiny.c (usbtiny_paged_load, usbtiny_paged_write):
-	fix breakage introduced by the recent page handling reorg;
-	it used to cause an infinite loop
-
-2012-05-04  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	Xmega page erase implementation for XPROG (AVRISPmkII, STK600)
-	* stk500v2.c (stk600_xprog_page_erase): New function.
-
-2012-05-04  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	Xmega page erase implementation for JTAGICEmkII
-	* jtagmkII.c: Handle flash pages sizes > 256 bytes, implement
-	page_erase() method
-	* avrdude.conf.in: Change flash pagesize for all Xmega devices
-	to 512 bytes
-	* avr.c: Implement auto_erase, using page_erase if available
-	* avr.h: Remove unused parameters from avr_read(), replace
-	unused parameter in avr_write)() by auto_erase
-	* stk500v2.c: Handle flash page sizes > 256 bytes
-	* update.c (do_op): Handle new updateflags parameter
-	* main.c: Implement auto_erase as page_erase if possible
-	* update.h (enum updateflags): New enum
-	* pgm.h (struct programmer_t): Add page_erase method
-
-2012-04-26  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* jtagmkII.c (jtagmkII_paged_load, jtagmkII_paged_write): fix bug
-	in memory type calculation for Xmega "boot" memory region.
-
-2012-04-25  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* update.c (parse_op): do not assume default memtype here
-	* main.c: after locating the part information, determine default
-	memtype for all update options that didn't have a memtype
-	specified; this is "application" for Xmega parts, and "flash" for
-	everything else.
-
-2012-04-24  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* fileio.c: Rework the way ELF file sections are considered: while
-	scanning the program header table, the offsets from a program
-	header entry must never be used directly when checking the bounds
-	of the current AVR memory region.  Instead, they must always be
-	checked based on the corresponding section's entry.  That way,
-	Xmega devices now properly take into account whether the segment
-	fits into any of the application/apptable/boot memory region.
-
-2012-04-20  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	bug #30756: When setting SUT to 64ms on XMEGA, avrdude doesn't
-	read device signature
-	* main.c: When reading the signature yields 0x000000 or 0xffffff,
-	retry (up to twice) after some progressive delay.
-
-2012-04-20  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* avrdude.conf.in (ATxmega16D4, ATxmega32D4, ATxmega64D4,
-	ATxmega128D4): New devices.  As Xmega D doesn't feature a fuse0
-	memory cell, move that one out from the generic .xmega part into
-	the individual Xmega A parts.
-
-2012-04-19  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	bug #29019: pagel/bs2 warning when uploading using stk500 to xmega
-	* stk500.c (stk500_initialize): Insert dummy values for PAGEL and
-	BS2 if they are not present in the config file, in order to be able
-	to proceed with the stk500_set_extended_parms() anyway.
-
-2012-04-19  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* stk500v2_private.h (struct pdata): add boot_start
-	* stk500v2.c: For the "flash" pseudo-memory of Xmega devices,
-	distinguish addresses between "application" and "boot" area.
-
-2012-04-18  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* fileio.c (elf2b): When checking the bounds of the current
-	program header segment, subtract `low' from ph[n].p_paddr in order
-	to correct the magic section offsets for the AVR's non-flash
-	memory regions.
-
-2012-04-18  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* fileio.c (elf_get_scn): Rather than trying to just match whether
-	any given section maps straight to a program header segment, use a
-	more sophisticated decision that matches any section as long as it
-	fits into the segment.  This is needed for situations where the
-	program header segment spans a larger area than the section data
-	provided.  (This can e.g. happen in an ELF file that contains no
-	data at address 0, like a bootloader only.)
-
-2012-04-13  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	bug #28744: Can't load bootloader to xmega128a1 (part 2, fix for
-	firmware >= V7.x)
-	* jtagmkII.c: Add firmware-version dependent handling of Xmega parameters.
-	V7.x firmware expects the NVM offsets being specified through the Xmega
-	parameters command, but left out as part of the memory address itself.
-	* jtagmkII_private.h: Add CMND_SET_XMEGA_PARAMS, and struct xmega_device_desc.
-	* config_gram.y: Add mcu_base keyword.
-	* avrpart.h: (Dito.)
-	* lexer.l: (Dito.)
-	* avrdude.conf.in (.xmega): add mcu_base, and data memory segment.
-
-2012-03-30  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	bug #28744: Can't load bootloader to xmega128a1 (part 1, fix for
-	firmware < V7.x)
-	* jtagmkII.c: When going to write to the boot section of flash,
-	use MTYPE_BOOT_FLASH rather than MTYPE_FLASH
-	* jtagmkII_private.h: add MTYPE_BOOT_FLASH constant
-
-2012-03-30  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* jtagmkII_private.h: Sort commands, response codes and events
-	into numerical order.
-
-2012-03-29  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	bug #30451: Accessing some Xmega memory sections gives not
-	supported error
-	* stk500v2.c: Handle all Xmega memory sections (except
-	"prodsig" which is not documented in AVR079)
-	* fileio.c: Treat the "boot", "application", and "apptable"
-	regions (which are actually subregions of "flash") all as
-	being flash, i.e. suppress trailing 0xFF bytes when reading
-	them
-	* avr.c: (Dito.)
-
-2012-03-20  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* jtagmkII.c (jtagmkII_close): The GO command before signing off
-	turned out to be not required for normal megaAVR devices, and to
-	cause the exact opposite (i.e. the target stopping) on Xmega
-	devices being programmed to JTAG.  However, programming Xmega
-	devcies through PDI *does* need the GO command.
-
-2012-03-20  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* configure.ac: Print a configuration summary at the end of the
-	configure run

-
-	bug #34302: Feature request : device configuration with parent classes
-	* config_gram.y: if memory section is overwritten old entry is removed
-	
-	(not in original patch)
-	* config_gram.y: if programmer or part is defined twice, a warning is
-	output and the first instance is removed
-	
-	General cleanup and free functions, so valgrind does not report any lost
-	blocks at program end.
-	* avrpart.[hc]: added avr_free_(opcode|mem|part) functions
-	* pgm.[hc]: added pgm_free function
-	* update.[hc]: added free_update functions
-	* config.[hc]: added cleanup_config function, use yylex_destroy to reset
-	the lexer after usage. (So it can be reused.)
-	* main.c: add cleanup_main function which is called by atexit() (This 
-	frees all lists so that at program exit only really lost memory is 
-	reported by valgrind.)
-	* usbasp.c: added libusb_free_device_list() and libusb_exit() calls to
-	avoid lost memory
-	* buspirate.c: moved memory allocation from initpgm to setup and added 
-	free in teardown
-	* configure.ac: add definition of HAVE_YYLEX_DESTROY if $LEX is flex.

-	error messages. avrftdi_print is changed so that a message is printed when
-	the verbosity level is greater or equal the message level, to have always-on
-	messages.
-	Fix a bug where the RX fifo of the FTDI chip is full, resulting in STALL/NAK
-	of the ongoing OUT request and subsequently timeout, because an IN request
-	cannot be issued due to the synchronous part of libftdi. This should fix
-	#38831 and #38659.

-	the interrupt transfers used).

-

-	jtag3_open_common() function to handle the common code of all

-Linux users: make sure the header files are installed
-=====================================================
-
-While many Linux distributions install the libraries needed by AVRDUDE
-(libusb, libelf) by default, they leave out the corresponding header

+# AVRDUDE
+
+[![Build Status](https://github.com/avrdudes/avrdude/actions/workflows/build.yml/badge.svg)](https://github.com/avrdudes/avrdude/actions/workflows/build.yml)
+
+AVRDUDE - AVR Downloader Uploader - is a program for downloading and uploading
+the on-chip memories of Microchip’s [AVR microcontrollers](https://en.wikipedia.org/wiki/AVR_microcontrollers).
+It can program the Flash and EEPROM, and where supported by the programming
+protocol, it can program fuse and lock bits.
+AVRDUDE also supplies a direct instruction mode allowing one to issue any
+programming instruction to the AVR chip regardless of whether AVRDUDE
+implements that specific feature of a particular chip.
+
+AVRDUDE was originally written in 2003 by Brian S. Dean. Since 2006, AVRDUDE has been maintained by Jörg Wunsch,
+with the help of [various contributors](./AUTHORS).
+
+The latest version of AVRDUDE is always available here:\
+<https://github.com/avrdudes/avrdude>
+
+## Getting AVRDUDE for Windows
+
+To get AVRDUDE for Windows, install the latest version from the [Releases](http://download.savannah.gnu.org/releases/avrdude/) page.
+
+Alternatively, you may [build AVRDUDE](https://github.com/avrdudes/avrdude/wiki) yourself from source.
+
+## Getting AVRDUDE for Linux
+
+To install AVRDUDE for Linux, install the package `avrdude` by running the following commands:
+
+```console
+sudo apt-get install avrdude
+```
+
+Alternatively, you may [build AVRDUDE](https://github.com/avrdudes/avrdude/wiki) yourself from source.
+
+## Getting AVRDUDE for MacOS
+
+On MacOS, AVRDUDE can be installed through Mac Ports.
+
+Alternatively, you may [build AVRDUDE](https://github.com/avrdudes/avrdude/wiki) yourself from source.
+
+## Using AVRDUDE
+
+AVRDUDE is a command-line application. Run the command `avrdude` without any arguments for a list of options.
+
+A typical command to program your HEX file into your AVR microcontroller looks like this:
+
+```console
+avrdude -c <programmer> -p <part> -U flash:w:<file>:i
+```
+
+For instance, to program an **Arduino Uno** connected to the serial port **COM1** with a HEX file called `blink.hex`,
+you would run the following command:
+
+```console
+avrdude -c arduino -P COM1 -b 115200 -p atmega328p -D -U flash:w:objs/blink.hex:i
+```
+
+There are many different programmers and options that may be required for the programming to succeed.
+

+
+## Feature Details
+
+### Support Atmel AVR programmers out of the box
+
+This build contains support for Atmel AVR programmers, such as
+
+- [Atmel-ICE](https://www.microchip.com/DevelopmentTools/ProductDetails/ATATMEL-ICE) (Part Number: ATATMEL-ICE)
+- [Atmel AVRISP mkII](https://www.microchip.com/DevelopmentTools/ProductDetails/PartNO/ATAVRISP2) (Part Number: ATAVRISP2)
+
+This build does not rely on **libusb** drivers. Instead the default Atmel drivers can be used, allowing you to use AVRDUDE and Atmel Studio 7 side-by-side, without switching drivers.
+
+If you previously changed the driver of your programmer to libusb, you should use **Windows Device Manager** to uninstall the device, and then reinstall using the default Windows drivers.
+
+### Support Micronucleus bootloader
+
+This build adds support for the [Micronucleus bootloader](https://github.com/micronucleus/micronucleus), so you do no longer need a separate command-line utility when working with devices that use the Micronucleus bootloader.
+
+The Micronucleus bootloader is typically used on small ATtiny boards, such as **Digispark** (ATtiny85), **Digispark Pro** (ATtiny167), and the respective clones.
+By default, it uses the USB VID/PID **16D0:0753** (MCS Digistump).
+
+Since this bootloader is optimized for size, it implements writing to flash memory only.
+As it does not support reading, you need to use the **-V** option to prevent AVRDUDE from verifing the flash memory. To have AVRDUDE wait for the device to be connected, use the extended option '-x wait'.
+
+#### Example: Flashing a Micronucleus bootloader device
+
+```console
+avrdude -c micronucleus -p t85 -x wait -V -U flash:w:main.hex:i
+```
+
+### Support Teensy HalfKay bootloader
+
+This build adds support for the [Teensy HalfKay bootloader](https://www.pjrc.com/teensy/halfkay_protocol.html), so you do no longer need a the Teensy Loader tool when working with Teensy devices.
+
+Since this bootloader is optimized for size, it implements writing to flash memory only.
+As it does not support reading, you need to use the **-V** option to prevent AVRDUDE from verifing the flash memory. To have AVRDUDE wait for the device to be connected, use the extended option '-x wait'.
+
+Supported devices are:
+
+- Teensy 1.0 (AT90USB162)
+- Teensy 2.0 (ATmega32U4)
+- Teensy++ 1.0 (AT90USB646)
+- Teensy++ 2.0 (AT90USB1286)
+
+#### Example: Flashing a Teensy 2.0 device
+
+```console
+avrdude -c teensy -p m32u4 -x wait -V -U flash:w:main.hex:i
+```
+
+### Support COM port discovery via USB VID/PID
+
+Most Arduino boards use a USB-based virtual COM port, which is connected to some sort of bootloader. Since COM port numbers (COM1, COM2, ...) are determined by Windows, you first need to use Windows device manager to figure out the COM port before you can use AVRDUDE to flash the board. Alternatively, you may use Windows device manager to assign a COM port of your choice to the USB device. Additionally, the COM port of your Arduino board may change over time, for instance if you plug the device in a different USB port.
+
+To simplify the discovery of your Arduino board, I provided the possibility to specify the USB vendor and product ID instead of the COM port.
+
+For instance, to connect to an Arduino Leonardo, use the following command:
+
+```console
+avrdude -c avr109 -P usb:2341:0036 -p m32u4
+```
+
+Since the USB vendor and device ID **2341:0036** is the identical for all Leonardo boards, the command above will work regardless of which COM port was actually assigned to your board.
+
+Note that can cannot use this method if you have more than one device of the same type (i.e. that share the same USB VID/PID) plugged into your computer. Also, some devices ship various versions of firmwares using different VID/PID.
+
+To figure out the USB VID and PID, you may use **Windows devices manager** (see the **Hardware IDs** of the **Details tab** of the USB device), or look it up in the official list of Arduino devices:
+<https://github.com/arduino/ArduinoCore-avr/blob/master/boards.txt>
+
+USB VID/PID pairs for some popular boards and the respective commands are:
+
+- Arduino Uno Rev 3: **2A03:0043** -> `avrdude -c arduino -P usb:2A03:0043 -p m328p`
+- Arduino Micro: **2341:0037** -> `avrdude -c avr109 -P usb:2341:0037 -p m32u4`
+- Arduino Leonardo: **2341:0036** -> `avrdude -c avr109 -P usb:2341:0036 -p m32u4`
+- Sparkfun Pro Micro (5V): **1B4F:9205** -> `avrdude -c avr109 -P usb:1B4F:9205 -p m32u4`
+- Sparkfun Pro Micro (3.3V): **1B4F:9203** -> `avrdude -c avr109 -P usb:1B4F:9203 -p m32u4`
+- Adafruit Circuit Playground: **239A:0011** -> `avrdude -c avr109 -P usb:239A:0011 -p m32u4`
+
+### Support Arduino Leonardo bootloader auto-reset
+
+Before any Arduino board may be flashed via the bootloader, you need to kick it into bootloader mode first. This can done manually by pressing the reset button, or automatically via an special auto-reset mechanism: For boards with a USB to serial converter chip (such as Arduino Uno or Nano), the tool needs to pull the DTR signal to low, which will briefly pull the RESET pin of the microcontroller to low. For boards with a direct USB connection (such as Arduino Leonardo or Micro), the sketch typically implements a serial port via a USB composite device with a virtual COM port. To perform the auto-reset, the sketch implements a hack that resets the device into bootloader mode when the COM port is opened with a baudrate of 1200bps. To make matters even more complicated, the bootloader COM port has a different USB VID:PID pair than the sketch COM port, which causes the COM port to change while performing the reset.
+
+To simplify the process of auto-resetting the board, this version will auto-reset the device when AVRDUDE detects that the device is running in sketch mode. Note that the sketch is required to implement a USB composite device with a virtual COM port with a matching USB VID:PID, which is implemented in the Arduino core software.
+
+### Support WinUSB devices via custom libusb
+
+Since AVRDUDE originated from Unix, the USB support in AVRDUDE is built upon the Unix-based USB library [libusb](https://sourceforge.net/projects/libusb/). In order to support Windows, libusb has been ported to Windows [libusb-win32](https://sourceforge.net/projects/libusb-win32/).
+
+The downside of using libusb-win32 is that it requires the user to manually install a kernel-mode driver (libusb0.sys or libusbk.sys)  instead of the manufacturer supplied Windows driver. There are several hacks to accomplish this, such as the [Zadig driver installation utility](https://zadig.akeo.ie/), which installs a self-signed root certificate in the Windows driver store due to the lack of proper driver installation packages.
+
+This build contains a custom library called **libwinusb**, which implements a sub-set of the libusb-win32 API. The libwinusb implementation supports both the **winusb.sys** driver, and the **libusb0.sys** driver as well. This patch has a number of advantages, such as
+
+- Many USB devices that ship with WinUSB drivers, such as Atmel programmer, will run out of the box.
+- Works with both WinUSB and libusb: You can use either Windows built-in WinUSB driver to access your USB devices, or keep using the libusb drivers if you have them installed already.
+- No static dependency to libusb0.dll: You cannot run the original version AVRDUDE, unless you previously installed libusb. On systems where libusb is not installed, this build eliminates the error "The code execution cannot proceed because libusb0.dll was not found. Reinstalling the program may fix this problem".
+
+#### Microsoft OS descriptors and firmware examples
+
+Windows provides a mechanism to automatically load the built-in WinUSB driver without providing a driver installation package (INF file). The automatic WinUSB driver installation is triggered via a special [Microsoft OS descriptor](https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/microsoft-defined-usb-descriptors) that must be present in the firmware of the USB device.
+
+To demonstrate how this works, I added Microsoft OS descriptors to the following projects:
+
+- **USBasp** - USB programmer for Atmel AVR controllers: <https://github.com/mariusgreuel/USBasp>
+
+- **FabISP** a.k.a **USBtinyISP** - A fab-able in-system programmer: <https://github.com/mariusgreuel/FabISP>
+
+- **Micronucleus** - ATtiny USB bootloader with a strong emphasis on bootloader compactness: <https://github.com/mariusgreuel/micronucleus>
+
+### Support FTDI devices via custom libftdi
+
+In order to support FTDI devices, AVRDUDE uses the Unix-based library [libftdi1](https://www.intra2net.com/en/developer/libftdi/). Similar to libusb, the libftdi1 library does not play nice on Windows: On Windows, FTDI devices load the manufacturer supplied driver via plug-and-play. The FTDI drivers implement an API via the FTDI D2XX DLLs. However, libftdi1 cannot use the D2XX interface, so it will not work with the plug-and-play drivers.
+
+This build contains a patches library of **libftdi**. The patches load the D2XX DLLs to support FTDI devices, so FTDI devices will just work.
+
+### Support HID devices via libhidapi
+
+This build include the WIN32 version of libhidapi, and some patches, to allow HID devices to work out of the box.
+
+### Support Visual Studio
+
+This build adds support for **Microsoft Visual Studio**. Building AVRDUDE with Microsoft Visual C/C++ will give you the best user and debugging experience while working on Windows.
+
+### Miscellaneous bug-fixes and patches
+
+- This build fixes [bug #54159: Buffer overflow in usbtiny.c](http://savannah.nongnu.org/bugs/?54159), which causes AVRDUDE to crash when using the USBtiny programmer.
+
+- Support new microcontroller: ATtiny167
+
+## Releases
+
+You can find the latest releases of **AVRDUDE for Windows** here:
+
+<https://github.com/mariusgreuel/avrdude/releases>
+
+## Users manual
+
+You can find the original users manual (does not contain AVRDUDE for Windows extras) of AVRDUDE here:
+
+<https://www.nongnu.org/avrdude/user-manual/avrdude.html>
+
+## Build
+
+The build instructions have been moved here:\
+<https://github.com/avrdudes/avrdude/wiki>
+
+### Building AVRDUDE for Windows using MSVC
+
+#### Windows Prerequisites
+
+In order to build AVRDUDE on Windows, you need:
+
+- Flex and Bison installed, for instance via [Chocolatey](https://chocolatey.org/)
+- Microsoft Visual Studio 2019 with **Desktop development with C++** and **CMake** enabled
+
+#### Windows Build Instructions
+
+To build AVRDUDE on Windows, do the following:
+
+- `git clone --branch windows https://github.com/mariusgreuel/avrdude`
+- Open the folder **avrdude** using the menu item **File->Open->Folder**
+- Build the project using the menu item **Build->Build All**
+
+### Linux udev rules
+
+If you intent to use either the Micronucleus or Teensy bootloader, you should edit the udev rules so that you can run AVRDUDE without root.
+
+For instance, if you are on Ubuntu and you installed the avrdude package, you would edit `/lib/udev/rules.d/60-avrdude.rules` and add the following rules:
+
+```console
+# Micronucleus Bootloader
+SUBSYSTEM=="usb", ATTR{idVendor}=="16d0", ATTR{idProduct}=="0753", TAG+="uaccess"
+# Teensy Bootloader
+SUBSYSTEM=="usb", ATTR{idVendor}=="16c0", ATTR{idProduct}=="0478", TAG+="uaccess"
+```
+
+## Troubleshooting Tips & Tricks
+
+### Atmel DFU Device driver broken
+
+The current version of the Atmel DFU drivers that are distributed via the Windows Update are goofed up (@Atmel: It might have something to do with the fact that you commented out the CopyFiles sections!).
+Symptoms are:
+
+- You cannot use AVRDUDE to connect to an Atmel DFU device, and you get the error message "No matching USB device found".
+- When installing the drivers via Windows Update, you get the error message "Windows encountered a problem installing the drivers for your device" and "A service installation section in this INF is invalid."
+- In Windows Device Manager, the Atmel DFU device shows up as an unknown device.
+
+You should use an older driver package that does not contain this bug.
+
+### Outdated libusb0 driver
+
+The most current version of libusb0.sys is 1.2.6.0, signed on 12/17/2012 by Travis Lee Robinson. If you are using an older version (check with Windows Device Manager), you may not be able to connect to your USB devices using the libusb0 driver.

+Under a Linux installation with direct access to the SPI bus and GPIO
+pins, such as would be found on a Raspberry Pi, the ``linuxspi''
+programmer type can be used to directly connect to and program a chip
+using the built in interfaces on the computer. The requirements to use
+this type are that an SPI interface is exposed along with one GPIO
+pin. The GPIO serves as the reset output since the Linux SPI drivers
+do not hold slave select down when a transfer is not occurring and thus
+it cannot be used as the reset pin. A readily available level
+translator should be used between the SPI bus/reset GPIO and the chip
+to avoid potentially damaging the computer's SPI controller in the
+event that the chip is running at 5V and the SPI runs at 3.3V. The
+GPIO chosen for reset can be configured in the avrdude configuration
+file using the
+.Li reset
+entry under the linuxspi programmer, or
+directly in the port specification. An external pull-up resistor
+should be connected between the AVR's reset pin and Vcc. If Vcc is not

 required, it is strongly advisable to protect the GPIO pins from 
 overcurrent situations in some way. The simplest would be to just put
 some resistors in series or better yet use a 3-state buffer driver like
 the 74HC244. Have a look at http://kolev.info/avrdude-linuxgpio for a more
 detailed tutorial about using this programmer type.
 
+Under a Linux installation with direct access to the SPI bus and GPIO
+pins, such as would be found on a Raspberry Pi, the ``linuxspi''
+programmer type can be used to directly connect to and program a chip
+using the built in interfaces on the computer. The requirements to use
+this type are that an SPI interface is exposed along with one GPIO
+pin. The GPIO serves as the reset output since the Linux SPI drivers
+do not hold slave select down when a transfer is not occuring and thus
+it cannot be used as the reset pin. A readily available level
+translator should be used between the SPI bus/reset GPIO and the chip
+to avoid potentially damaging the computer's SPI controller in the
+event that the chip is running at 5V and the SPI runs at 3.3V. The
+GPIO chosen for reset can be configured in the avrdude configuration
+file using the @code{reset} entry under the linuxspi programmer, or
+directly in the port specification. An external pull-up resistor
+should be connected between the AVR's reset pin and Vcc. If Vcc is not
+the same as the SPI voltage, this should be done on the AVR side of
+the level translator to protect the hardware from damage.
+
+On a Raspberry Pi, header J8 provides access to the SPI and GPIO
+lines.
+
+Typically, pins 19, 21, and 23 are SPI MOSI, MISO, and SCK, while
+pins 24 and 26 would serve as CE outputs. So, close to these pins
+is pin 22 as GPIO25 which can be used as /RESET, and pin 25 can
+be used as GND.

+--------------------
+@end example
+
+There are several limitations in current SerialUPDI/AVRDUDE integration,
+listed below.
+
+At the end of each run there are fuse values being presented to the user.
+For most of the UPDI-enabled devices these definitions (low fuse, high
+fuse, extended fuse) have no meaning whatsoever, as they have been 
+simply replaced by array of fuses: fuse0..9. Therefore you can simply
+ignore this particular line of AVRDUDE output.
+
+In connection to the above, @emph{safemode} has no meaning in context
+of UPDI devices and should be ignored.
+
+Currently available devices support only UPDI NVM programming model 0 
+and 2, but there is also experimental implementation of model 3 - not
+yet tested.
+
+One of the core AVRDUDE features is verification of the connection by
+reading device signature prior to any operation, but this operation
+is not possible on UPDI locked devices. Therefore, to be able to 
+connect to such a device, you have to provide @option{-F} to override
+this check.
+
+Please note: using @option{-F} during write operation to locked device 
+will force chip erase. Use carefully.
+
+Another issue you might notice is slow performance of EEPROM writing
+using SerialUPDI for AVR Dx devices. This can be addressed by changing
+@emph{avrdude.conf} section for this device - changing EEPROM page 
+size to 0x20 (instead of default 1), like so:
+
+@example
+#------------------------------------------------------------
+# AVR128DB28
+#------------------------------------------------------------
+
+part parent    ".avrdx"
+    id        = "avr128db28";
+    desc      = "AVR128DB28";
+    signature = 0x1E 0x97 0x0E;
+
+    memory "flash"
+        size      = 0x20000;
+        offset    = 0x800000;
+        page_size = 0x200;
+        readsize  = 0x100;
+    ;
+
+    memory "eeprom"
+        size      = 0x200;
+        offset    = 0x1400;
+        page_size = 0x1;
+        readsize  = 0x100;
+    ;
+;
+@end example
+
+USERROW memory has not been defined for new devices except for 
+experimental addition for AVR128DB28. The point of USERROW is to 
+provide ability to write configuration details to already locked
+device and currently SerialUPDI interface supports this feature,
+but it hasn't been tested on wide variety of chips. Treat this as
+something experimental at this point. Please note: on locked devices
+it's not possible to read back USERROW contents when written, so
+the automatic verification will most likely fail and to prevent
+error messages, use @option{-V}.
+
+Please note that SerialUPDI interface is pretty new and some
+issues are to be expected. In case you run into them, please
+make sure to run the intended command with debug output enabled
+(@option{-v -v -v}) and provide this verbose output with your
+bug report. You can also try to perform the same action using
+@emph{pymcuprog} (@url{https://github.com/microchip-pic-avr-tools/pymcuprog})
+utility with @option{-v debug} and provide its output too.
+You will notice that both outputs are pretty similar, and this
+was implemented like that on purpose - it was supposed to make
+analysis of UPDI protocol quirks easier.

+
+// Notes:
+// This file adds support for the Micronucleus bootloader V1 and V2,
+// so you do no longer need the Micronucleus command-line utility.
+//
+// This bootloader is typically used on small ATtiny boards,
+// such as Digispark (ATtiny85), Digispark Pro (ATtiny167),
+// and the respective clones.
+// By default, it bootloader uses the VID/PID 16d0:0753 (MCS Digistump).
+//
+// As the micronucleus bootloader is optimized for size, it implements
+// writing to flash memory only. Since it does not support reading,
+// use the -V option to prevent avrdude from verifing the flash memory.
+// To have avrdude wait for the device to be connected, use the
+// extended option '-x wait'.
+//
+// Example:
+// avrdude -c micronucleus -p t85 -x wait -V -U flash:w:main.hex
