How to set MPU6886 Acceleromer/Gyro range and FIFO sample frequency?

[mgrouch]

How can I read built-in mpu6886 FIFO on atomS3?
M5Unified library doesn't have an example and looking at the code
many methods for FIFO are commented out and made non-public.

Can someone provide an example? I need higher sample rate and
synchronized gyro and accelerometer samples. The FIFO register supports burst reads of synchronized data for the specified data rate. The interrupt function is used to determine when new data is available.

Looks like using FIFO is only correct way to get accurate data.

Thanks
