Function Documentation

adxl367_adc_read_en()

int adxl367_adc_read_en	(	struct adxl367_dev *	dev,
		bool	enable )

Enables ADC reading. Disables temperature reading.

Parameters

dev	- The device structure.
enable	- 1 - ENABLE 2 - DISABLE

Returns

0 in case of success, negative error code otherwise.

adxl367_fifo_setup()

int adxl367_fifo_setup	(	struct adxl367_dev *	dev,
		enum adxl367_fifo_mode	mode,
		enum adxl367_fifo_format	format,
		uint8_t	sets_nb )

Configures the FIFO feature. Uses ADXL367_14B_CHID read mode as default.

Parameters

dev	- The device structure.
mode	- FIFO mode selection. Example: ADXL367_FIFO_DISABLED, ADXL367_OLDEST_SAVED, ADXL367_STREAM_MODE, ADXL367_TRIGGERED_MODE
format	- FIFO format selection. Example: ADXL367_FIFO_FORMAT_XYZ, ADXL367_FIFO_FORMAT_X, ADXL367_FIFO_FORMAT_Y, ADXL367_FIFO_FORMAT_Z, ADXL367_FIFO_FORMAT_XYZT, ADXL367_FIFO_FORMAT_XT, ADXL367_FIFO_FORMAT_YT, ADXL367_FIFO_FORMAT_ZT, ADXL367_FIFO_FORMAT_XYZA, ADXL367_FIFO_FORMAT_XA, ADXL367_FIFO_FORMAT_YA, ADXL367_FIFO_FORMAT_ZA
sets_nb	- Specifies the number of samples sets to store in the FIFO.

Returns

0 in case of success, negative error code otherwise.

adxl367_get_g_xyz()

int adxl367_get_g_xyz	(	struct adxl367_dev *	dev,
		struct adxl367_fractional_val *	x,
		struct adxl367_fractional_val *	y,
		struct adxl367_fractional_val *	z )

Reads the 3-axis raw data from the accelerometer and converts it to g.

Parameters

dev	- The device structure.
x	- Stores the X-axis data.
y	- Stores the Y-axis data.
z	- Stores the Z-axis data.

Returns

0 in case of success, negative error code otherwise.

adxl367_get_nb_of_fifo_entries()

int adxl367_get_nb_of_fifo_entries	(	struct adxl367_dev *	dev,
		uint16_t *	entr_nb )

Reads the number of FIFO entries.

Parameters

dev	- The device structure.
entr_nb	- Entries number. Different from sets number. For example, if ADXL367_FIFO_FORMAT_XYZ is selected, one set contains 3 entries.

Returns

0 in case of success, negative error code otherwise.

adxl367_get_raw_xyz()

int adxl367_get_raw_xyz	(	struct adxl367_dev *	dev,
		int16_t *	x,
		int16_t *	y,
		int16_t *	z )

Reads the 3-axis raw data from the accelerometer.

Parameters
