- most were trivial
- missing group close or open
- extra space
- no doxygen comment
- name commad might open an implicit group
this hould also be implicit cosed but does not happen somtimes
- crazy: internal declared groups have to be closed internal
The following features were tested (briefly):
* UART (the first, and the second connected to the UBlox SARA)
* xtimer
* I2C (using driver BMX280 and SHT2x)
* ADC
* WDT
* RGB-LEDs
SPI isn't tested, but it should be working.
