Are there more, and where do I find them defined?
From  I assume:
- XS1 G-Series
- XS1 A-Series
- XS1 U-Series
- XS1 XA-series
- XS1 L-Series
- __???__ (or maybe not needed since they aren't programmeable as such(?))
- xCORE-AUDIO family
- xCORE-VOICE family
I need it because I am trying to port a library from the Arduino (ardiohead ), and if I am lucky the code may be just #ifdef'ed version of it. But to be honest I doubt it, since I would need other file names and also will absolutely use XMOS libraries when they're there. But it's worth a try.
