int anaIn(int channel, int gaincode);
Reads the state of an A/D converter input channel. If the access is for an A/D converter single-ended
bipolar channel and the gain code for the 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 to 7) corresponding to AIN0–AIN7

RETURN VALUE
A value corresponding to the voltage or current on the analog input channel (0–2047 for 11-bit
conversions).
