Yesterday I put my new APM and IMU shield together and would like to now make sure that I did not destroy them in the process. I found a couple of tests in the repository and these seem to be fine (haven't tested the GPS yet).
For the Ardu Imu I have seen some tests that apparently run the DCM and output Euler angles, etc. For the mega I have found a blog post by Jose Julio here:http://diydrones.com/profiles/blog/show?id=705844%3ABlogPost%3A148919
But this seem to be somewhat outdated (at least the ADC channels seem wrong when comparing them to the APM_ADC test). Does naybody know of outher tests for the IMU oilpan? (I'm new to this :)
