Dev_SensorOffsetCal()

static void __inline__ Dev_SensorOffsetCal ( SENSOR_OFFSET_CAL_t *  sensor, uint16_t  adcReading  )

static

Parameters

sensor	pointer to object of type SENSOR_OFFSET_CAL_t
adcReading	most recent ADC reading

Returns

void

This function takes number of samples of adc sample for averaging before acquiring the sensor offset value and checks if it is in the acceptable range before setting the calibration bit complete.

Initial value:

= {.CalibrationComplete = false,
                                               .Accumulator = 0,
                                               .MeasurementCounter = 0,
                                               .LimitHigh = ISEC_AVG_SENSOR_OFFSET_LIMIT_HIGH,
                                               .LimitLow = ISEC_AVG_SENSOR_OFFSET_LIMIT_LOW}

The 'isecAvgCurrentSensor' data object holds the averaging parameter of the sensor offset calibration.
