Constructor & Destructor Documentation

Adafruit_LSM303_Accel_Unified()

Adafruit_LSM303_Accel_Unified::Adafruit_LSM303_Accel_Unified

(

int32_t

sensorID = -1

)

Instantiates a new Adafruit_LSM303 class.

Parameters

sensorID

an optional identifier for the sensor instance

Member Function Documentation

begin()

bool Adafruit_LSM303_Accel_Unified::begin	(	uint8_t	i2c_address = LSM303_ADDRESS_ACCEL,
		TwoWire *	wire = &Wire
	)

Sets up the hardware and initializes I2C.

Parameters

i2c_address	The I2C address to be used.
wire	The Wire object to be used for I2C connections.

Returns

True if initialization was successful, otherwise false.

getEvent()

bool Adafruit_LSM303_Accel_Unified::getEvent

(

sensors_event_t *

event

)

Gets the most recent sensor event, Adafruit Unified Sensor format.

Parameters

event

Pointer to an Adafruit Unified sensor_event_t object that we'll fill in

Returns

True on successful read

setRange()

void Adafruit_LSM303_Accel_Unified::setRange

(

lsm303_accel_range_t

new_range

)

Sets the accelerometer's range.

Parameters

new_range

an lsm303_accel_range_t representing the range of measurements in +/-G. The smaller the range, the more accurate.

getRange()

lsm303_accel_range_t Adafruit_LSM303_Accel_Unified::getRange

(

void

)

Gets the accelerometer's range.

Returns

The lsm303_accel_range_t representing the range of measurements in +/-G.

getMode()

lsm303_accel_mode_t Adafruit_LSM303_Accel_Unified::getMode

(

void

)

Get the accelerometer's power mode.

Returns

The lsm303_accel_mode_t representing the power mode.

setMode()

void Adafruit_LSM303_Accel_Unified::setMode

(

lsm303_accel_mode_t

new_mode

)

Sets the accelerometer's power mode.

Parameters

new_mode

an lsm303_accel_mode_t representing the power mode. The mode effects the precision of the sensor's readings High resolution is 12-bit Normal mode is 10-bit Low power is 8-bit

interruptsActiveHigh()

void Adafruit_LSM303_Accel_Unified::interruptsActiveHigh

(

bool

active_high

)

Sets the polarity of the interrupt pins.

Parameters

active_high

Set to true for the INT pints to be active high, false for active low
