ParallelComm Library

Non-blocking library to send/receive data through digital pins between uC or between cores on the same uC (not tested yet).

Motivation

CPU cycle hungry projects where it is not possible at all to make any CPU blocking serial calls.

In my case, an audio DSP consumes almost all of the CPU leaving only a few time available, enough to configure digital pins and transfer data to another uC connected to an Oled Display.

You can send up to 16 bits per message or split into any number of values concatenated up to 16 bits.
