    Not sure if you are going to see the same problem with the T3.6. I ran the i2c at 400Khz and it the IMU just hung no data after a few seconds. Same thing at 1000000 but it worked for a little then hung again. Onehorse mentioned that its a timer issue with i2c_t3 library. Next time I load the sketch up I will give 3.4M a try and see what happens.

    Odd - I never saw that normally of course i2c_t3 was a recent addition - I did when I pushed for higher rates over 400K with Wire - but not when I went to the Standard 3.4M as MAX - it keeps running with no hang.

    i2c_t3 readme lists faster rates based on Teensy and clocking level : github.com/nox771/i2c_t3
