Small and lightweight MIDI protocol library that allows transmit MIDI messages.
Originally, it was written for Arduino Uno in order to send MIDI messages to guitar effects that have MIDI inputs.
Arduino IDE could be used: https://www.arduino.cc/en/Main/Software. Be noticed - keep *.ino at the same directory with midi.c midi.h (using Arduino IDE only).
Also Makefile could be written or try Arduino.mk from https://github.com/sudar/Arduino-Makefile/blob/master/Arduino.mk
