int anaInCalib(int channel, int opmode,
int gaincode, int value1, float volts1,
int value2, float volts2);
Calibrates the response of a given A/D converter channel as a linear function using the two conversion
points provided. Gain and offset constants are calculated and placed into global table _adcInCalib.
PARAMETERS
channel is the analog input channel number (0 to 7) corresponding to AIN0–AIN7

opmode is the mode of operation for the specified channel. Use one of the following macros to set the
mode for the channel being configured.
0 = Single-Ended unipolar (0–20 V)
1 = Single-Ended bipolar (±10 V)
2 = Differential bipolar (±20 V)
3 = 4–20 mA
gaincode is the gain code of 0 to 7 (use a gain code of 4 for 4–20 mA operation)

value1 is the first A/D converter value (0–4095).
volts1 is the voltage corresponding to the first A/D converter value.
value2 is the second A/D converter value (0–4095).
volts2 is the voltage corresponding to the second A/D converter value.
