root int anaInEERd(unsigned int channel,
unsigned int opmode, unsigned int gaincode);
Reads the calibration constants, gain, and offset for an input based on their designated position in the
simulated EEPROM area of the flash memory, and places them into global tables _adcCalibS,
_adcCalibD, and _adcCalibM for analog inputs. The constants are stored in the top 2K of the user
block in a reserved memory area. Depending on the flash size, the following macros can be used to
identify the starting address for these locations.
ADC_CALIB_ADDRS, address start of single-ended analog input channels
ADC_CALIB_ADDRD, address start of differential analog input channels
ADC_CALIB_ADDRM, address start of milliamp analog input channels
NOTE: This function cannot be run in RAM.
PARAMETER
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 line
DIFF—differential input line
mAMP—milliamp input line
