• LSM303DLHC datasheet (1MB pdf)

  Datasheet for the ST LSM303DLHC 3D accelerometer and 3D magnetometer module.

• Using LSM303DLH for a tilt-compensated electronic compass (1MB pdf)

  An application note by ST on how to use the LSM303DLH as a tilt-compensated compass. This application note mostly applies to the very similar LSM303DLM as well (when replacing the DLH with the DLM, the main difference to note is that the magnetometer Y and Z registers have been swapped).

• UM10204 I²C-bus specification and user manual (1MB pdf)

  The official specification for the I²C-bus, which is maintained by NXP.

• LSM303 Arduino library

  This is a library for the Arduino that interfaces with our LSM303D, LSM303DLHC, and LSM303DLM 3D compass and accelerometer carriers as well as the compass and accelerometer ICs on the MinIMU-9 v3 and AltIMU-10 v4 (it also works with older versions of those boards, some of which used the LSM303DLH and LSM303DLHC). It makes it simple to configure the device and read the raw accelerometer and magnetometer data, and it has a function for computing the tilt-compensated heading for those looking to use the LSM303 as a tilt-compensated compass.

• mbed library for the LSM303DLH

  This is a library for the ARM mbed 4d玉蒲团奶水都喷出来了免费 board that interfaces with the LSM303DLH 3D compass and accelerometer carrier and provides the tilt-compensated magnetic heading. It can be easily modified to work with the newer and very similar LSM303DLHC 3D compass and accelerometer carrier by swapping the magnetometer Y and Z registers. This library was not written and is not maintained by Pololu.

• Quick and Dirty Compass Calibration in 3d

  A blog post by Michael Shimniok about calibrating the magnetometer in the LSM303DLH and visualizing magnetic distortions. This information can generally be applied to other magnetometers as well.

  This sketch outputs a text-based graph of LSM303 accelerometer and L3G gyro data, providing a quick way to check whether the sensors are working as expected.
