float anaInDiff(int channel, int gaincode);
Reads the state of a differential A/D converter input channel and uses the previously set calibration con-
stants to convert it to volts. If the gain code for a given channel has changed from the previous cycle, the
EEPROM will be read to get the calibration constants for the new gain value.
PARAMETER
channel is the analog input channel number (0, 2, 4, 6) as shown below
gaincode
is the gain code of 0 to 7

RETURN VALUE
A voltage value corresponding to the voltage on the analog input channel. A value of -4096 indicates an
overflow or out-of-range condition.
