Hi Baltika,
Thanks for the feedback, I will look at that MPU. Happy to hear you have got it working, but I'd love to hear the results of your tests![/quote]
Let me say first of all that the test I've carried out is not very scientific so beware when inferring conclusions. I simply held the IMU in my hand and manipulated it. That alone is bound to induce so errors as it is impossible for me to hold it in a fixed heading while twisting it. I moved the IMU + and - to around 40° of roll and pitch. When roll only is involved the heading remained pretty consistent (given that I was holding it in my hands) suggesting that some sort of compensation for that motion was happening. However when pitch is involved there is a clear indication that the heading does deviate significantly.
I would have liked to have been able to carry out something a little more rigorous but at the moment I can't I'm afraid. I offer my results fully in the knowledge that they are error prone but please don't beat me up about that.
