Parameters

desc	- The device structure.
ch	- Diagnostic channel index.
status	- Enabled or disabled status.

Returns: 0 in case of success, negative error code otherwise.

◆ ad74413r_set_info()

int ad74413r_set_info	(	struct ad74413r_desc *	desc,
		uint16_t	mode
	)

Select which information the device will respond with (in the readback field) when a read operation is performed.

Parameters

desc	- The device structure.
mode	- Possible values: 0 - Respond with the readback address. 1 - Respond with status bits.

Returns: 0 in case of success, negative error otherwise.

◆ ad74413r_set_therm_rst()

int ad74413r_set_therm_rst	(	struct ad74413r_desc *	desc,
		bool	enable
	)

Enable or disable the higher thermal reset.

Parameters

desc	- The device structure.
enable	- The thermal reset status. false: reset at 110 deg. Celsius. true: reset at 140 deg. Celsius.

Returns: 0 in case of success, negative error code otherwise.

◆ ad74413r_set_threshold()

int ad74413r_set_threshold	(	struct ad74413r_desc *	desc,
		uint32_t	ch,
		uint32_t	threshold
	)

Set the threshold, for which a signal would be considered high, when the ADC is running in digital input mode.

Parameters

desc	- The device structure.
ch	- The channel index.
threshold	- The threshold value (in millivolts). The actual threshold set might not match this value (~500mV max. error), since it's fairly low resolution (29 possible values).

Returns: 0 in case of success, negative error code otherwise.

Set a fixed range (0 - 16 V) for the threshold, so it would not depend on Vadd.
