Remi Beges / DistantIO

Framework for reading and writing variables in real time on any MBED platform.

DistantIO

This is the C implementation of the DistantIO slave framework.

Library is working but slight API breaks may occur in the future. C++ version is also in development.

To get the master-side implementation, see https://github.com/Overdrivr/DistantIO
