I just noticed that the samr21-xpro still has no ADC support and was
wondering if maybe someone from the watr.li team could upstream their
implementation..?
Or take over the existing PR https://github.com/RIOT-OS/RIOT/pull/2063 ?
in general I would do so. As part of watrli I already worked with this PR and improved some things locally (which I mostly commented inside the PR). IIRC @wiredsource stated several times that he wants to finish the implementation. @wiredsource are you reading this? What's the status from your side?
as we are planning to use the Demo we had @ Embedded World also for "Lange Nacht der Wissenschaften" next Saturday, I have it also on my plate, to get a working ADC implementation for the SAMR21 this week.
@wiredsource: Are you planning to do anything on that PR this week? Otherwise I would like to take over.
