work in progress - ADC channels can be read with DiffPressureSensor library, but need calibration
tested with variable voltage into Analog pins with modified PCB at AREF to allow for AREF REFSEL1 - voltage divider does not seem to directly match Xmega AREF, so additional calibration in code in DiffPressureSensor library. See shift and gain. Range is currently 0 to ~2V
cleaned up library - now analogSensor.h -- use for sensing voltage at pins PA1 through PA6
Motor_shield_proto ready - as shipped -- Pressure sensors are calibrated in Hive
