• m3y54m/start-avr: Getting started with AVR programming using AVR-GCC and Makefile
• hexagon5un/AVR-Programming: Code examples for the book "Make: AVR Programming"
• avrdudes/avrdude: AVRDUDE is a utility to program AVR microcontrollers

AVR chips require a 'programmer' and some software.

• programmers
  • USBasp - USB programmer for Atmel AVR controllers - fischl.de
  • AVRISP MK2
  • ATMEL-ICE
  • STK500

• to run avrdude without superuser, a udev rule like the following is needed (common group name is uucp)

  # Set group for a programmer matching with vendor and product IDs
   SUBSYSTEM=="usb", ATTRS{idVendor}=="your Vendor ID", ATTRS{idProduct}=="your Product ID", GROUP="uucp", MODE="0666"
