Enumeration Type Documentation

◆ dwIMUAlignmentStatus

enum dwIMUAlignmentStatus

High rate data output from GNSS-IMU device requires fusion of GNSS and IMU.

The data can only be accurate if the GNSS/IMU device has gone through an internal alignment initialization, which allows the device to know the orientation of the IMU. This status indicates the quality of IMU alignment.

Enumerator
DW_IMU_ALIGNMENT_STATUS_UNKNOWN	Unknown status means the device does not or has not yet provided this information.
DW_IMU_ALIGNMENT_STATUS_INVALID	Invalid means the IMU alignment is not yet valid, and the output data is not accurate.
DW_IMU_ALIGNMENT_STATUS_COARSE	Coarse means the IMU is roughly aligned, so the data is useful, but not of the highest quality.
DW_IMU_ALIGNMENT_STATUS_FINE	Fine means the IMU alignment is complete, and the device can output high quality data.
DW_IMU_ALIGNMENT_STATUS_FORCE32

Function Documentation

◆ dwSensorIMU_popFrame()

DW_API_PUBLIC dwStatus dwSensorIMU_popFrame	(	dwIMUFrame *const	frame,
		dwSensorHandle_t const	sensor
	)

Returns any IMU data previously processed through the raw data stream.

This happens on the CPU thread where the function is called, incurring an additional load on that thread.

Parameters

[out]	frame	Pointer to an IMU frame structure to be filled with new data.
[in]	sensor	Sensor handle of the sensor previously created with 'dwSAL_createSensor()'.

Returns: DW_INVALID_HANDLE - if given sensor handle is invalid.
DW_INVALID_ARGUMENTS - if given arguments are invalid.
DW_NOT_AVAILABLE - if no more data is available
DW_SUCCESS

◆ dwSensorIMU_popFrameNew()

DW_API_PUBLIC dwStatus dwSensorIMU_popFrameNew	(	dwIMUFrameNew *const	frame,
		dwSensorHandle_t const	sensor
	)

Returns any IMU Frame New previously processed through the raw data stream.

This happens on the CPU thread where the function is called, incurring an additional load on that thread.

Parameters

[out]	frame	Pointer to an IMU frame New structure to be filled with new data.
[in]	sensor	Sensor handle of the sensor previously created with 'dwSAL_createSensor()'.

Returns: DW_INVALID_HANDLE - if given sensor handle is invalid.
DW_INVALID_ARGUMENTS - if given arguments are invalid.
DW_NOT_AVAILABLE - if no more data is available
DW_SUCCESS

◆ dwSensorIMU_processRawData()

DW_API_PUBLIC dwStatus dwSensorIMU_processRawData	(	uint8_t const *const	data,
		size_t const	size,
		dwSensorHandle_t const	sensor
	)

Reads the IMU frame from raw data.

Any processed messages can be picked up using the dwSensorIMU_readFrame() method. This happens on the CPU thread where the function is called, incurring an additional load on that thread.

Parameters

[in]	data	Undecoded imu data.
[in]	size	Size in bytes of the raw data.
[in]	sensor	Sensor handle of the sensor previously created with 'dwSAL_createSensor()'.

Returns: DW_INVALID_HANDLE - if given sensor handle is invalid,
DW_INVALID_ARGUMENTS - if given arguments are invalid,

DW_API_PUBLIC dwStatus dwSensorIMU_processRawDataNew	(	uint8_t const *const	data,
		size_t const	size,
		dwSensorHandle_t const	sensor
	)

Reads the IMU frame New from raw data.

Any processed messages can be picked up using the dwSensorIMU_readFrameNew() method. This happens on the CPU thread where the function is called, incurring an additional load on that thread.

Parameters

[in]	data	Undecoded imu data.
[in]	size	Size in bytes of the raw data.
[in]	sensor	Sensor handle of the sensor previously created with 'dwSAL_createSensor()'.

Returns: DW_INVALID_HANDLE - if given sensor handle is invalid,
DW_INVALID_ARGUMENTS - if given arguments are invalid,
DW_NOT_READY - if more data needs to be passed in (loop while it returns 'DW_NOT_READY').
DW_SUCCESS

◆ dwSensorIMU_readFrame()

DW_API_PUBLIC dwStatus dwSensorIMU_readFrame	(	dwIMUFrame *const	frame,
		dwTime_t const	timeoutUs,
		dwSensorHandle_t const	sensor
	)

Reads the next IMU frame from the sensor within a given timeout.

The method blocks until either a new valid frame is received from the sensor or the given timeout is exceeded.

Parameters

[out]	frame	A pointer to an IMU frame structure to be filled with new data.
[in]	timeoutUs	Timeout, in us, to wait for a new message. Special values: DW_TIMEOUT_INFINITE - to wait infinitely. Zero - means polling of internal queue.
[in]	sensor	Sensor handle of the IMU sensor previously created with dwSAL_createSensor().

Returns: DW_INVALID_HANDLE - if given sensor handle is invalid
DW_INVALID_ARGUMENTS - if given arguments are invalid
DW_TIME_OUT - if operation has timeout
DW_NOT_AVAILABLE - if sensor has not been started or data is not available in polling mode.
DW_END_OF_STREAM - if end of stream reached (virtual sensor only).
DW_SAL_SENSOR_ERROR - if there was an i/o or bus error.
DW_SUCCESS

DW_API_PUBLIC dwStatus dwSensorIMU_readFrameNew	(	dwIMUFrameNew *const	frame,
		dwTime_t const	timeoutUs,
		dwSensorHandle_t const	sensor
	)

Reads the next IMU frame New from the sensor within a given timeout.

The method blocks until either a new valid frame is received from the sensor or the given timeout is exceeded.

Parameters

[out]	frame	A pointer to an IMU frame New structure to be filled with new data.
[in]	timeoutUs	Timeout, in us, to wait for a new message. Special values: DW_TIMEOUT_INFINITE - to wait infinitely. Zero - means polling of internal queue.

Returns: DW_INVALID_HANDLE - if given sensor handle is invalid
DW_INVALID_ARGUMENTS - if given arguments are invalid
DW_TIME_OUT - if operation has timeout
DW_NOT_AVAILABLE - if sensor has not been started or data is not available in polling mode.
DW_END_OF_STREAM - if end of stream reached (virtual sensor only).
DW_SAL_SENSOR_ERROR - if there was an i/o or bus error.
