MPU 9250 Support

[scottp]

Due to stock level, I got given a 9250 the other day instead of a 9150. However I can't work out the main differences yet to get it to work. Has anyone tried to get the 9250 working with this library? Scott

I have the same problem.
Can someone give guidance how to make MPU9250.cpp file or what might be the differences

[kirilligum]

I do get an output but i'm not sure what the numbers are

Hi, I'm sitting in the same boat and would also be very interested in i2cdevlib support for the MPU 9250.

Have you seen http://www.sureshjoshi.com/embedded/invensense-imus-what-to-know/?

The MPU-6050 is higher power, lower noise, and larger package versus the MPU-6500. Most of your code should port over, but some low power features are different and will need to be recoded in. Basic data acquisitions shouldn’t have changed.

The MPU-9150 contains the MPU-6050 and an AK8975 magnetometer from AKM. The MPU-9250 contains a MPU-6500 and AK8963. The same differences between gyro/accel are the same you see with 6050 v. 6500. The magnetometer on the MPU-9250 is a little better across the board.

Has anyone simply tried using the MPU-9150 code with the MPU-9250? It might work as-is, with the exception of some low-power features.

Also, I think i2cdevlib is a dead unmaintained project now. There are pull requests that have opened for years. You should look around at other projects like;

Hi!
This work is helpful.
However, I think a calibration app is needed to MPU9250.
You can reference this one,
MPU6050 calibration
I this it's useful, but I don't know how to adapt this app to MPU9250.
Can anyone help me?
