PJON Documentation

PJON implements a totally software emulated network protocol stack in around 1500 lines of code, thanks to the strategies abstraction it can work nominally with any data-link is in use and can be applied in a variety of media and applications. This library can be cross-compiled (-std=c++11) to work with virtually every Arduino compatible board or linux machine, for example ATtiny85 or Raspberry Pi.

Thanks to the interfaces abstraction, PJON can be easily ported on any MCU/architecture exposing random generation, timing and IO system calls (for example on Arduino: random, micros, pinMode).
