Arduino code for IMU Guide algorithm. Using a 5DOF IMU (accelerometer and gyroscope combo)

This article introduces an  implementation of a simplified filtering algorithm that was inspired by Kalman filter. The Arduino code is tested using a 5DOF IMU unit from GadgetGangster – Acc_Gyro . The theory behind this algorithm was first introduced in my Imu Guide article.

The Acc_Gyro is mounted on a regular proto-shield on top of an Arduino Duemilanove board.

Accelerometer Experiments – Part 2: LIS331AL and DE-ACCM2G (ADXL322) . Filters, amplifiers and vibration response.

In a previous article I have analized 3 accelerometer side by side comparing their noise level. Today I am going to test a 3 axis accelerometer from ST  LIS331AL. I am going to compare it with the DE-ACCM2G accelerometer from Dimension Engeneering.

For testing purposes I have mounted the LIS331AL on a break-out board. If you're interested how this board can be done and device mounted make sure you read my article "DIY Surface Mount on a Budget".

I have connected both accelerometers to my USB Gamepad device  and will be using the Gamepad Configuration Software to trace the signals (although an osciloscope could be used instead).
