int anaInCalib(int channel, int opmode, int gaincode, int value1, float volts1, int value2, float volts2);

Calibrates the response of the desired A/D converter channel as a linear function using the two conver- sion points provided. Four values are calculated and placed into global tables _adcCalibS, _adcCalibD, and adcCalibM to be later stored into simulated EEPROM using the function anaInEEWr(). Each channel will have a linear constant and a voltage offset.

PARAMETERS

channel is the analog input channel number (0 to 7) corresponding to LN0_IN to LN7_IN opmode is the mode of operation:

SINGLE—single-ended input DIFF—differential input mAMP—milliamp input

channel	SINGLE	DIFF	mAMP
0	+AIN0	+AIN0 -AIN1	+AIN0*
1	+AIN1	+AIN1 -AIN0*	+AIN1*
2	+AIN2	+AIN2 -AIN3	+AIN2*
3	+AIN3	+AIN3 -AIN2*	+AIN3
4	+AIN4	+AIN4 -AIN5	+AIN4
5	+AIN5	+AIN5 -AIN4*	+AIN5
6	+AIN6	+AIN6 -AIN7*	+AIN6
7	+AIN7	+AIN7 -AIN6*	+AIN7*

* Not accessible on Prototyping Board.

gaincode is the gain code of 0 to 7:

Gain Code	Multiplier	Voltage Range*
		(V)
0	×1	0–22.5
1	×2	0–11.25
2	×4	0–5.6
3	×5	0–4.5
4	×8	0–2.8
5	×10	0–2.25
6	×16	0–1.41
7	×20	0–1.126
