Function Documentation

ad4692_configure_acc_mask()

int ad4692_configure_acc_mask	(	uint16_t	channel_mask,
		enum ad4692_sequencer_modes	sequencer,
		uint8_t *	chn_priorities
	)

Configure the accumulator mask.

Parameters

channel_mask[in]	- Channel mask (Applicable in case of standard sequencer)
sequencer[in]	- Sequencer mode
chn_priorities[in]	- Channel priority (Applicable in case of advanced sequencer)

Returns

0 in case of success, negative error code otherwise.

Here is the caller graph for this function:

ad4692_configure_channel_priorities()

int ad4692_configure_channel_priorities	(	uint8_t *	chn_priorities,
		uint8_t *	channel_sequence,
		uint8_t *	num_of_as_slots,
		uint8_t *	acc_count
	)

Configure the advanced sequencer slots.

Parameters

chn_priorities[in]	- channel priorities to be configured
channel_sequence[out]	- Channel sequence as configured in the AS Slots
num_of_as_slots[out]	- Number of slots in the advanced sequencer
acc_count[in]	- Accumulator count limit

Returns

0 in case of success, negative error code otherwise.

This function configures the advanced sequencer slots based on the priorities assigned to each channel(max 2 priorities are allowed in the application). Example: If the user configures the following channels as P1 (highest priority): Ch0,Ch1,Ch2 and the following as P2 (Least priority): Ch3,Ch4 Then the advanced sequencer configurations would look like: Ch0-Ch1-Ch2-Ch3-Ch0-Ch1-Ch2-Ch4

Here is the caller graph for this function:

ad4692_toggle_cnv()

int ad4692_toggle_cnv

(

struct no_os_gpio_desc *

gpio_cnv

)

Toggle CNV GPIO.

Parameters

gpio_cnv[in,out]

- GPIO CNV Descriptor

Returns

0 in case of success, negative error code otherwise.
