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
Building the cross compiler and setting up the Lazarus IDE:
- Getting started Lazarus and Arduino (Uno/Nano) - How do I set up Lazarus to program an Arduino (AVR - Cross compiler).
- Set up Lazarus for ATtiny and ATmega - Lazarus cross compilation for additional Arduino/AVRs.
- Tool for creating and modifying AVR/Arduino projects: AVR/ Arduino Package - sechshelme (external link).
- Various programmers - hardware connections to flash the AVR.
AVR programming examples
