In some google searching I did not find a micropython driver for the FXOS8700 or FXAS21002. If anyone knows of one I would appreciate it if you could post it or send it to me or something.

Thanks

I am not aware of one. You will find various IMU drivers at micropython-imu. If you need sensor fusion I recommend the BNo055 which performs it on-chip with great effectiveness.

There are CircuitPython drivers for both the FXOS8700 and the FXAS21002. Both will be trivial to port to MicroPython - just change some references to the way I2C is handled. Let me know if you get stuck!

I'd also suggest a design change: just pass an I2C object to each of the drivers rather than create an I2C object.
