Where to find source code for Pyboard classes?

[BillG]

I'd like to read the source code for the Pyboard class ADC library. Where do I find this? I've fished around in github but don't see it. I found "stmhal" in micropython-master and it contains adc.c, but there must be a Python layer above that.

That adc.c file that you found is the interface. It's C code which implements the python interface.

You can find the documentation for the python interface here:
http://docs.micropython.org/en/latest/p ... b.ADC.html

For example, the read method: http://docs.micropython.org/en/latest/p ... b.ADC.read is implemented here:
https://github.com/micropython/micropyt ... #L252-L259

Thanks, Dave. I read through adc.c more thoroughly overnight and saw the notations for interfacing to Python.
