Reads the state of a differential analog input channel and uses the previously set calibration constants to
convert it to volts.
PARAMETERS
channel is the channel number (0, 2, 4, 6):
gaincode is the gain code of 0 to 7.
RETURN VALUE
A voltage value corresponding to the voltage on the analog input channel.
