Some days ago I wrote about noise with a LIS302DL accelerometer. There is obviously something wrong with my hardware. But before I get a new version out I need to implement some software filtering. After some unsuccessful results with low pass filters I choose the Kalman Filter. The Kalman Filter involves an awful lot of [...]

As you probably know, I really like I2C sensors and especially the LIS302DL. But adding this accelerometer to your circuit is not as straight forward as I thought. But in the end I got it quite right. It all started out with a 0.1µF ceramic capacitor. For good measure I put a ferrite bead in [...]
