float anaInVolts(unsigned int channel,
unsigned int gaincode);
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.
