RabbitCore RCM4000
Reads the state of a single-ended analog input channel and uses the previously set calibration constants to
convert it to volts.
PARAMETERS
channel
is the channel number (0 to 7) corresponding to LN0_IN to LN7_IN
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.
ADTIMEOUT
(defined macro = -4095) if conversion is incomplete or busy-bit timeout.
