Function Documentation

adxrs453_get_rate()

float adxrs453_get_rate

(

struct adxrs453_dev *

dev

)

Reads the rate data and converts it to degrees/second.

Parameters

dev	- The device structure.

Returns

rate - The rate value in degrees/second.

< If data received is in positive degree range

< If data received is in negative degree range

adxrs453_get_register_value()

uint16_t adxrs453_get_register_value	(	struct adxrs453_dev *	dev,
		uint8_t	register_address
	)

Reads the value of a register.

Parameters

dev	- The device structure.
register_address	- Address of the register.

Returns

register_value - Value of the register.

Here is the caller graph for this function:

adxrs453_get_sensor_data()

uint32_t adxrs453_get_sensor_data

(

struct adxrs453_dev *

dev

)

Reads the sensor data.

Parameters

dev	- The device structure.

Returns

register_value - The sensor data.

adxrs453_get_temperature()

float adxrs453_get_temperature

(

struct adxrs453_dev *

dev

)

Reads the temperature sensor data and converts it to degrees Celsius.

Parameters

dev	- The device structure.

Returns

temperature - The temperature value in degrees Celsius.

adxrs453_init()

int32_t adxrs453_init	(	struct adxrs453_dev **	device,
		struct adxrs453_init_param	init_param
	)

Initializes the ADXRS453 and checks if the device is present.

Parameters

device	- The device structure.
init_param	- The structure that contains the device initial parameters.

Returns

status - Result of the initialization procedure. Example: 0 - if initialization was successful (ID starts with 0x52). -1 - if initialization was unsuccessful.

adxrs453_remove()

int32_t adxrs453_remove

(

struct adxrs453_dev *

dev

)

Free the resources allocated by adxrs453_init().

Parameters

dev	- The device structure.

Returns

ret - The result of the remove procedure.

adxrs453_set_register_value()

void adxrs453_set_register_value	(	struct adxrs453_dev *	dev,
		uint8_t	register_address,
		uint16_t	register_value
	)

Writes data into a register.

Parameters

dev	- The device structure.
register_address	- Address of the register.
register_value	- Data value to write.

Returns

None.
