LSM303AGR

Arduino library to support the LSM303AGR 3D accelerometer and 3D magnetometer

API

This sensor uses I2C to communicate. It is then required to create a TwoWire interface before accessing the sensors:

TwoWire dev_i2c(I2C2_SDA, I2C2_SCL);  
dev_i2c.begin();

An instance can be created and enabled following the procedure below:

LSM303AGR_ACC_Sensor Acc(&dev_i2c);
Acc.begin();
Acc.Enable();
LSM303AGR_MAG_Sensor Mag(&dev_i2c);
Mag.begin();
Mag.Enable();

The access to the sensor values is done as explained below:

Read accelerometer and magnetometer.

int32_t accelerometer[3];
int32_t magnetometer[3];
Acc.GetAxes(accelerometer);
Mag.GetAxes(magnetometer);
