I’m running into trouble trying “the simple test” code
My mcu :
MicroPython v1.11-312-g22099ab88 on 2019-09-15; ESP32 module (spiram) with ESP32
Error:

How do you know there is a conflict? Does the internal accelerometer use the same address as the attachhed MPU9250?
Honestly I think Tuupola has got much more interesting things to deal with in this project (like working on the gyro calibration). @pidou64 take a closer look at the error message. If you are getting a result from the
i2c.scan()
then you can move on to the next step. Make sure that the correct address for your device is stated in the file mpu6500.py, line 88. The hexadecimal address here is 0x68 by default. My mpu9250 sensor address is decimal 105, or hexidecimal 0x69. I changed it in the code and all works now. If your sensor’s address is 41 decimal, then you might try changing the address in the code to 0x29
