LSM9DS0

LSM9DS0 9DOF sensor AHRS sketch

Like the original LSM9DS0_simple.ino sketch, it'll demo the following:

In addition, the sketch will demo:

A discussion of the use and limitations of this sensor and sensor fusion in general is found here.

I added a sketch specifically for the LSM9DS0 Mini and Micro-Add-On shields. It uses a Teensy 3.1-specific i2c Wire library called i2c_t3.h, which allows easy access to Teensy-specific capabilities such as specification of which set of hardware i2c pins will be used, the bus speed (up to 1 MHz!) and also allows master and/or slave designation to handle multiplexing between i2c devices. See www.pjrc.com/teensy and http://forum.pjrc.com/threads/21680-New-I2C-library-for-Teensy3 for details.

A description of the modular Teensy Project which uses the LSM9DS0 motion sensor, among others, is described here.
