Detailed Description

ADXL345 Accelerometer on I2C.

This class alows access to a Analog Devices ADXL345 3-axis accelerometer on an I2C bus. This class assumes the default (not alternate) sensor address of 0x3A (8-bit address).

Constructor & Destructor Documentation

ADXL345_I2C::ADXL345_I2C ( uint8_t  moduleNumber, ADXL345_I2C::DataFormat_Range  range = kRange_2G  )

explicit

Constructor.

Parameters

moduleNumber	The digital module that the sensor is plugged into (1 or 2).
range	The range (+ or -) that the accelerometer will measure.

ADXL345_I2C::~ADXL345_I2C ( )

virtual

Destructor.

Member Function Documentation

double ADXL345_I2C::GetAcceleration ( ADXL345_I2C::Axes  axis )

virtual

Get the acceleration of one axis in Gs.

Parameters

axis	The axis to read from.

Returns

Acceleration of the ADXL345 in Gs.

ADXL345_I2C::AllAxes ADXL345_I2C::GetAccelerations ( )

virtual

Get the acceleration of all axes in Gs.

Returns

Acceleration measured on all axes of the ADXL345 in Gs.
