Implements the Arduino APIs such as digitalRead, analogRead, Serial and more for general-purpose AVRs.

Some code is directly from the official Arduino core, others is reimplemented.

Note that this is slimmed down to my specific purposes, such as no floating points, no String and other space-saving measures.

How To Compile

• Have avr-gcc on your path with the standard avr libc headers available
• Edit Makefile if needed; change clock speed or device
• run make
