Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
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:
dev_i2c = new TwoWire(I2C2_SDA, I2C2_SCL);
dev_i2c->begin();
An instance can be created and enbaled following the procedure below:
Acc = new LSM303AGR_ACC_Sensor(dev_i2c);
Acc->Enable();
Mag = new LSM303AGR_MAG_Sensor(dev_i2c);
Mag->Enable();
The access to the sensor values is done as explained below:
Read accelerometer and magnetometer.
Acc->GetAxes(accelerometer);
Mag->GetAxes(magnetometer);
