Static data gathering

  1. I get small spikes in the IMU_ACCX/Y/Z graphs at exactly the same spots on each logging run. Is this OK?
    1. Yes, this happens with a lot of boards and is normal.  This is due to a voltage spike that may occur (for an as-of-yet unknown reason). To confirm the source of the spike, try graphing your  LOG_VOLTAGE8, 9, & 10 values — you should see similar spikes in exactly the same spots.  From Bill Nesbitt, the creator of AQ1: “The small noise section you get is typical. I’m not exactly sure where it comes from, could be a lot of things, but I see it quite often. No worries.”  See this thread for more graph examples.
