RabbitCore RCM3750
Reads the state of differential analog input channels and uses the calibration constants previously set
using
anaInCalib
to convert it to volts.
PARAMETERS
channel
is the analog input channel number (0 to 7) corresponding to ADC_IN0 to ADC_IN7
gaincode
is the gain code of 0 to 7
RETURN VALUE
A voltage value corresponding to the voltage on the analog input channel.
ADOVERFLOW
(defined macro = -4096) if overflow or out of range.
