AVR embedded tutorials

This is an overview of tutorials for programming AVR microcontrollers with Free Pascal and Lazarus. This includes various ATtiny and ATmega microcontrollers. Most of the examples also run on an Arduino with an ATmega; especially the Uno/Nano. The Arduino-Mega can also be programmed. Basically, all AVR microcontrollers are programmed more or less the same way. Usually only the registers differ a little.

Set up cross compiler/IDE
