MODSERIAL with support for more devices
Dependents: 1D-Pong BMT-K9_encoder BMT-K9-Regelaar programma_filter ... more
Check the cookbook page for more information: https://mbed.org/cookbook/MODSERIAL
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.
