User’s Manual 61
Calibrates the response of the A/D converter channel as a linear function using the two conversion points
provided. Four values are calculated and placed into global table
_adcCalib
to be stored later store
into simulated EEPROM using the function
anaInEEWr()
. Each channel will have the following
information:
a linear constant,
a voltage offset,
a calculation gain code used to calculate calibrations, and
a user gain code to set voltage range (defaults to the calculation gain code).
NOTE: Vcc monitoring is disabled when
anaInCalib
is running.
PARAMETERS
channel is the analog input channel number (0 to 7) corresponding to AIN0–AIN7
opmode
is the mode of operation:
SINGLE —single-ended input line
DIFF
—differential input line
mAMP
—milliamp input line
int anaInCalib(int channel, int opmode,
int gaincode, int value1, float volts1,
