User’s Manual 53
Reads the state of an analog input channel and uses the previously set calibration constants to convert it
to volts.
PARAMETERS
channel is the analog input channel number (0 to 7) corresponding to AIN0–AIN7
opmode is the mode of operation:
SINGLE —single-ended input line
DIFF —differential input line
gaincode is the gain code of 0 to 7:
RETURN VALUE
A voltage value corresponding to the voltage on the analog input channel.
