MPU6886 example not compilling

[pgrawehr]

In the examples folder, there's an example for the MPU6886 imu. Unfortunately, it does not compile, because 'class M5Tough' has no member named 'IMU'. Looking at the code, that is correct, there's no reference whatsoever to an IMU in the declaration of the M5 class. According to the documentation, I'm not even sure the M5Though does have an IMU/MPU.

Can you clearify whether that example is supposed to work? Is there an IMU in the M5Though, and if so, what type is it?

Hello @pgrawehr

according to the specifications the M5Tough does not have an MPU.

Thanks

@felmue Looks like it, yes. But since I doubt a bit the quality of that documentation I really wasn't sure (the page on the very similar Core2 is much longer).

Bottom line is probably that this example should be deleted, as it is missleading.

Hello @pgrawehr

I agree, the documentation isn't always up-to-date and often contains copy / paste errors. That said I confirmed the lack of an MPU by running an I2C scan on the internal I2C bus - only three responses (Touch IC, AXP, and RTC).

@imliubo - I agree with @pgrawehr the MPU6886 example should probably be deleted.

Thanks

This is an example that shouldn't exist, sorry for being misleading, we've removed it
