44 RabbitCore RCM3600
Reads the state of a single-ended analog input channel and uses the calibration constants previously set
using
anaInCalib
to convert it to volts.
PARAMETERS
channel
is the channel number (0–7)
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.
