The documentation is pretty good but it describes the usage with original Arduino IDE which is not my weapon of choice. Some time ago I noticed PlatformIO added support for this device so I wanted to use it.

The measuring device has to be small, look professional and have low power consumption so it can run on batteries. In next lines I’ll describe how I have achieved this.

Turning ST-Link programmer into IR controlled USB keyboard

As I promised last time, I’m going to continue with st-link programmer clones. This time I wanted to use mbed which has some ready made libraries for utilizing USB and since it was very comfortable to use DFU upload with arduino library, at first I checked if it is usable with mbed too.
