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

Revision:
2:f2c816b681e3
Parent:

Child:

*Fixed issues with variables/group names > 8; *Added timing management. Variables can either be send all the time, or only after a defined delta. Useful to reduce constraints on datarate for parameters not needed in real time
