Arduino compatible, C++ library to Read/Write to Joybus protocol devices (N64, GameCube controllers) over UART in a non-blocking way (no bit bang). Interrupts aren't blocked or used.
(Ab)uses Serial Port to emulate the OneWire-like protocol of Joybus, based on the work published by qwertymodo (http://www.qwertymodo.com/hardware-projects/n64/n64-controller).
In order to wire this up, we need to tie the UART's Rx and Tx pins together using a Schottky diode, as shown here (https://github.com/dword1511/onewire-over-uart).
Hardware required: serial port (uart) capable of 1250000 bps baud-rate.
