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
