Hi,
Been playing around with the LSM303DLH coupled to an Arduino Uno and using a MD01B for linear actuator motor control.
Application is a compass based autopilot system
Problem is compass noise induced by vibration. The accelerometers are affecting the heading value erroneuosly. I verified the default configuration (via LSM303 data sheet) for the accelerometers is at the lowest gain and capped at +/- 2g.
What I want to do is turn the accelerometers “off”. I want a non tilt comp compass to baseline. After that I can start playing games with Low/Band/High pass filters on the accelerometer inputs…
Before I go and butcher the lsm303.h and .cpp files I wanted to ask the Pololu Forum group if they had ever done this (turn accel input off) before and if there was a preferred method.
