I have bought a mpu9255 module(no mpu9250 found). I connect it to esp32s3 with sda、scl、vcc and gnd. However, when i check the data from uart, IMU initialization unsuccessful. I check the sda scl vcc and gnd via voltmeter，the volitage is ok with normal status. Is reason that i cannot use mpu9250.h for the mpu9255 module? If it is right, i cannot find mpu9255.h, can you give me some links?

Hello, this IMU is not supported. You need to keep in mind that this is a homebrew project, so I can't cover all possible combinations of IMU modules, magnetometers, etc.... If you agree, your issue needs a workaround, and if you're okay with it and don't think it's urgent, I've created a new branch to change the libraries so that it can include multiple IMU and compass modules. However, my time for dedication is limited.

You can see the latest stable version. There was from a year ago.

Keep in mind new revisions and possible bugs are wellcome.

ok. I changed the module to mpu9255 and "IMU initialization successful".
