setup_sd_adc_calibration( )
Syntax:
setup_sd_adc_calibration(model);
Parameters: mode- selects whether to enable or disable calibration mode for the SD ADC
module. The following defines are made in the device's .h file:
SDADC_START_CALIBRATION_MODE
SDADC_END_CALIBRATION_MODE
Returns:
Function:
Availability:
Examples:
Nothing
To enable or disable calibration mode on the Sigma-Delta Analog to
Digital Converter (SD ADC) module. This can be used to determine
the offset error of the module, which then can be subtracted from
future readings.
Only devices with a SD ADC module.

set_sd_adc_channel( )
Syntax:
setup_sd_adc(channel);
Parameters: channel- sets the SD ADC channel to read. Channel can be 0 to read the
difference between CH0+ and CH0-, 1 to read the difference between CH1+
and CH1-, or one of the following:
SDADC_CH1SE_SVSS
SDADC_REFERENCE
