- Sample Code
- We have written a basic Arduino library for this LSM303 carrier board that makes it easy to interface this sensor with an Arduino or Arduino-compatible board like an A-Star. The library makes it simple to read the raw accelerometer and magnetometer data, and it has a function for computing the tilt-compensated heading for those looking to use this sensor as a tilt-compensated compass.
