I looked in the OBEX, but could not find anything for the ADC chip that is on the Activity Board. I believe all the support code for the Activity Board is PropCCC. The ADC that is on the Propeller BOE, is a different one than what is on the Activity Board. Same holds true for the C3 board.
I am doing some testing of the fastspin(BASIC) program, and I am using the WX Activity Board as the test unit. Now that I think about it, I will probably need the Spin version for the WiFi part also, if anybody has some leads.
