A library to control MX28 servos. It could also be used with the rest of the MX series servos.

Dependents:   IDcheck

Fork of MX28 by Georgios Petrou

This library is based on Robotis documentation regarding the dynamixel and MX28 protocols

It is part of a bigger project involving seven mbeds to control a hexapod robot.

I have not tried to control other MX series servos, but it should be possible to use this library with minor modifications.
