    Hey Paul, yes I tried doing that early on. Actually as I'm trying to debug this I only have the control box and nothing but the IMU connected. The only thing that helps is not calling leds.show(). Without that call the...

    I don't know how to really interpret this but it seems the library somehow borks i2c. Another debug trace: Received: Header: 12 00 05 BA Body: 4B 10 FF 02 D0 00 D0 3D 00 00 00 00 00 00 Length:18...

    Im trying to use this with a bno080 over i2c but what happens is, the frame-rate drops for a while then the sensor doesn't return readings anymore. If I don't call leds.show(), the sensor works normally. Could this...

    Yes the quats update at 1khz (and you also get the gyro data). The IMU integrates it from the gyro and corrects it with the underlying rotation vector every 100hz. This period is adjustable and you can also choose which...

    I have been playing with it recently (use it in my balancing robot). I fixed up SPI a bit and added support for gyro integrated rotation vector. It still needs some testing but, I can get 1 khz updates with gyro...
