In my development, I generally will develop without the actual Arduino board. As the mapping on the ATmega328 is different than the Arduino mapping it simplifies my workflow. If you want an example of ...

Procure one Atmega328 chip with pre-burned Arduino Bootloader; Replace the original chip in your Arduino board with this one; ... Pin 15 on the IC is actually the pin for Digital Pin 9 (D9) on the ...

A register level simulation of the ATMega328 (Arduino Uno) processor. Register level being between bit level and API level, meaning it doesn't just simulate Arduino code and isn't a total replication ...

I picked out one of the 3x ProtoStack ATmega328 Developments Kits they donated. I’ve been messing around with my Arduino Uno for a while and was looking to expand my Atmel AVR knowledge a bit and ...
