How to get data from MPU9250?

[Ericir3]

Is there any functions that can get data from MPU9250?

Sorry buddy, not yet, you need to use I2C to read.
You can refer to https://github.com/RockySong/micropython-rocky/blob/omv_initial_integrate/ports/nxp_lpc546/tests2/sensors.py, and modify to fit to MPU2950.
There is also a sensor fusion library "ay_imu" in this repo, and demo script https://github.com/RockySong/micropython-rocky/blob/omv_initial_integrate/ports/nxp_lpc546/tests2/main.py
Welcome to port these stuff to MPU9250 on i.MX RT1050 and send pull request!

Thanks for your reply and i'll try it. I think there's a small mistake in README.md that MPU9250 uses I2C3 but not I2C4(注：如需使用，会占用I2C扩展口(I2C4)，因此其它器件的I2C slave地址不要与它(7位地址0x68/0x69)冲突。). Hope you can confirm that.

In file "pin_mux.c", there is no pin settings for LPI2C3 or LPUART4. I just wonder how you realize I2C or UART transmit and receive functions with micropython?

[RockySong]

This not implemented with pin_mux.c, as pins are re-allocated dynamically. The mechanism is defining pins in i2c.h or uart.h.
