Cy_DSADC_CalibrateAchan0_2TempTrim()

void Cy_DSADC_CalibrateAchan0_2TempTrim	(	PACSS_DCHAN_Type *	base,
		cy_en_dsadc_achan0_2temp_trim_gain_type_t	gain,

	)

Calibrate the gain and the offset correction values for the ACHAN0 with the value derived from the calibration data stored in SFLASH.

Note

Applicable to PSOC4 HVPA only. The accuracy of the correction values are [-1, 1]. If the temperature value is out of range, then trim value is calculated with the minimum or the maximum temperature.

Parameters

base	The base address for the Digital Channel.
gain	The gain value for the ACHAN0 see cy_en_dsadc_achan0_2temp_trim_gain_type_t.
temperature	Temperature in fixed point format Q12.20. CY_DSADC_TEMPERATURE_FRACTION_BITS

		int32_t	temperature
	)

Calibrate the gain and the offset correction values for the ACHAN1 with the value derived from the calibration data stored in SFLASH.

Note

		int32_t	temperature
	)

Calibrate the gain and the offset correction values for the ACHAN1 with the value derived from the calibration data stored in SFLASH.

Note

Applicable to PSOC4 HVPA only. The accuracy of the correction values are [-1, 1]. If the temperature value is out of range, then trim value is calculated with the minimum or the maximum temperature.
