Dependents:   1D-Pong BMT-K9_encoder BMT-K9-Regelaar programma_filter ... more

Did you add a device? Please send a pull request so we can keep everything in one library instead of many copies. In that case also send a PM, since currently mbed does not inform of new pull requests. I will then also add you to the developers of this library so you can do other changes directly.
