Is there a well-established way to interface with the ADC on the beaglebone?
Is there a driver in the kernel for it already? If so, where does it show up?
If a driver needs to be written for the ADC, where could I find the documentation on the ADC "chip" (OK, core) it uses?
I'll probably end up using an external ADC anyway-- I'd rather not injecting scary analog input directly into the little thing's CPU-- but in case I do end up finding a use for the internal ADC, I'm curious how to do it.
