Using the Beagle Bone black ADC

The BBB has a fast 12 bit ADC. It has a 7 channel front end and does 12 bit conversions. It can sample as fast as 100 kHz (100 microsecond conversions)

Signals must be in the range 0 - 1.8 volts.

The ADC on the BBB can be used as a touch screen controller (TSC). If it is used as one there will be lines left over that can still be ADC inputs.

There may be a driver named "tiadc"
