Joerg Wunsch 8c6c6a14ec Remove the "safemode" feature. 
This feature has been designed with the sometimes quite flakey direct
(parallel or serial port attached) bitbang programming adapters in
mind that were quite common about two decades ago.

With parallel ports vanishing from modern PCs almost completely, and
the advent of various USB-attached low-cost programming devices,
this class of programmers disappeared almost completely.

Furthermore, the fuse combinations that were covered by the feature
are no longer around on all recent AVR devices, so for an ever
increasing number of devices, safemode already became meaningless and
was turned off anyway.

With the prospective version 7.x release, it's a good point in time to
introduce a major change like this one.

AVRDUDE

Build Status

AVRDUDE - AVR Downloader Uploader - is a program for downloading and uploading the on-chip memories of Microchip’s 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.

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 page.

Alternatively, you may build AVRDUDE yourself from source.

Getting AVRDUDE for Linux

To install AVRDUDE for Linux, install the package avrdude by running the following commands:

sudo apt-get install avrdude

Alternatively, you may build AVRDUDE yourself from source.

Getting AVRDUDE for MacOS

On MacOS, AVRDUDE can be installed through Mac Ports.

Alternatively, you may build AVRDUDE 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:

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:

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.

For more information, refer to the AVRDUDE documentation.
