all on non-paged-memory parts. The problem was that the page size was
defaulting to 256 (maximum for the stk500), but the timeout for a
response from the stk500 before declaring it dead was only 0.5
seconds. But it takes much longer than 0.5 seconds to program 256
bytes, so we just weren't waiting long enough.
Fix this in two ways - increase the timeout to 5 seconds, and decrease
the page size to 16 bytes for non-paged parts. The programming time
for 16 bytes is short enough to provide the user with some feedback
that something is happening.

one of the programmers to be tagged "default" within its definition.
Also, axe the notion of a compiled-in default programmer. It is
kind've pointless now that nearly all configuration comes from the

and thus, having a programmer compiled-in offers little or no benefit.

in ppi.c to help with portability. Change the programmer type to
'PAR' now instead of 'PPI' - 'PAR' represents the parallel port
programmer type.
Be more liberal with 'static' function declarations within the
programmer implimentation files - these functions should never be
called directly - always use the programmer function references.
There are still a few places in 'main.c' that directly reference the

This change represents a name change only. There is currently an
effort to port AVRPROG to other platforms including Linux and Windows.
Since Atmel's programmer binary that's included within their AVR
Studio software is named AVRPROG.EXE on the Windows OS, there is the
chance for confusion if we keep calling this program AVRPROG as well.
Up until now the name hasn't really been a problem since there was no
chance to confuse 'avrprog' on Unix with Atmel's AVRPROG because
Atmel's tools only run on Windows. But with the Unix 'avrprog'
possibly being ported to Windows, I felt a name change was the best
way to avoid problems.
So - from this point forward, my FreeBSD Unix program formerly known
as AVRPROG will subsequently be known as AVRDUDE (AVR Downloader/UploaDEr).
This change also represents a time when the AVRDUDE sources move from
my own private repository to a public repository. This will give
other developers a chance to port AVRDUDE to other platforms and
extend its functionality to support additional programming hardware,
etc.
So goodbye AVRPROG, welcome AVRDUDE!

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
buffer is enabled to avoid a short period of time where the AVR may be
driving the programming lines at the same time the programmer tries
to. Of course, if a buffer is being used, then the /RESET line from
the programmer needs to be directly connected to the AVR /RESET line
and not via the buffer chip.

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.

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.

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.

find information about.

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.

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.

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.

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.

the history.

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.

Make binary format the default for output.
Update the parts table with corrections for old values and add some
new values.

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.

Clean up debugging code a little, utilize fileio() instead of making
direct calls to b2ihex().
git-svn-id: svn://svn.savannah.nongnu.org/avrdude/trunk@21 81a1dc3b-b13d-400b-aceb-764788c761c2
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.
