Function Documentation

adc_npcx_threshold_ctrl_enable()

int adc_npcx_threshold_ctrl_enable	(	const struct device *	dev,
		uint8_t	th_sel,
		const bool	enable
	)

Enables/Disables ADC threshold interruption.

Note

This function is available only if CONFIG_ADC_CMP_NPCX is selected.

Parameters

dev	Pointer to the device structure for the driver instance.
th_sel	Threshold selected.
enable	Enable or disables threshold interruption.

Returns

0 on success, negative error code otherwise. all parameters must be configure prior enabling threshold interruption, otherwise error will be returned.

adc_npcx_threshold_ctrl_set_param()

int adc_npcx_threshold_ctrl_set_param	(	const struct device *	dev,
		const uint8_t	th_sel,
		const struct adc_npcx_threshold_param *	param
	)

Set ADC threshold parameter.

Note

This function is available only if CONFIG_ADC_CMP_NPCX is selected.

Parameters

dev	Pointer to the device structure for the driver instance.
th_sel	Threshold selected.
param	Pointer of parameter structure. See struct adc_npcx_threshold_param for supported parameters.

Returns

0 on success, negative error code otherwise.

adc_npcx_threshold_mv_to_thrval()

int adc_npcx_threshold_mv_to_thrval	(	const struct device *	dev,
		uint32_t	val_mv,
		uint32_t *	thrval
	)

Convert input value in millivolts to corresponding threshold register value.

Note

This function is available only if CONFIG_ADC_CMP_NPCX is selected.

Parameters

dev	Pointer to the device structure for the driver instance.
val_mv	Input value in millivolts to be converted.
thrval	Pointer of variable to hold the result of conversion.

Returns

0 on success, negative result if input cannot be converted due to overflow.
