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 to be later stored into sim-
ulated 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 ADC_IN0 to ADC_IN7
opmode is the mode of operation:
SINGLE—single-ended input
DIFF—differential input
mAMP—milliamp input
