- 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 setter function approach makes this switchable at runtime (antenna
diversity?).
Documentation is added both to the board introduction page and the
individual pins and functions.
The particle-{argon,boron,xenon} all have a uFL connector and a PCB
antenna for 2.4GHz radio, connected by a SKY13351-378LF switch
configured by a VCTL[12] pin pair.
This sets the default configuration to use the PCB antenna, as driving
an unconnected antenna will deteriorate radio performance.
