Detailed Description

FSYNC configuration and polling helpers for the ICM-42670-P.

Function Documentation

ICM42670_Disable_Fsync()

ICM42670_Status_t ICM42670_Disable_Fsync

(

const ICM42670_Config *

config

)

Disable FSYNC timestamp capture and clear FSYNC interrupt routing.

Parameters

config

Driver configuration with read, write, and delay callbacks.

Returns

ICM42670_OK on success, otherwise ICM42670_ERROR or ICM42670_BUSY.

References ICM42670_ERROR, ICM42670_FSYNC_INT_NONE, and ICM42670_OK.

ICM42670_Enable_Fsync()

ICM42670_Status_t ICM42670_Enable_Fsync	(	const ICM42670_Config *	config,
		const ICM42670_FsyncConfig_t *	fsync_config
	)

Enable FSYNC timestamp capture with simple defaults.

Passing NULL for fsync_config selects rising-edge FSYNC, no UI data LSB tag, clear-on-sensor-update behavior, and no interrupt routing.

Parameters

config	Driver configuration with read, write, and delay callbacks.
fsync_config	Optional FSYNC configuration, or NULL for defaults.

Returns

ICM42670_OK on success, otherwise ICM42670_ERROR or ICM42670_BUSY.

ICM42670_Read_Fsync()

ICM42670_Status_t ICM42670_Read_Fsync	(	const ICM42670_Config *	config,
		ICM42670_FsyncData_t *	fsync_data
	)

Read the read-clear FSYNC event status and latest FSYNC timestamp.

Parameters

config	Driver configuration with a read callback.
fsync_data	Destination for event status and timestamp data.

Returns

ICM42670_OK on success, otherwise ICM42670_ERROR.
