Wrong IMU pins

Describe the bug

The sketch M5StickC-Plus/examples/Basics/IMU/IMU.ino doesn't work because the line imu6886.Init(32, 33) is wrong. With my device, it should be imu6886.Init(GPIO_NUM_21, GPIO_NUM_22).

To reproduce

  1. Compile and run M5StickC-Plus/examples/Basics/IMU/IMU.ino => IMU readings are random

Expected behavior

IMU readings are correct

Oops, it seems I'm using the wrong version of IMU.ino... Please let me investigate and clarify this.

Ok, this is puzzling. There are two sketches for testing the IMU in this repo:

  1. https://github.com/m5stack/M5StickC-Plus/tree/master/examples/Basics/IMU
  2. https://github.com/m5stack/M5StickC-Plus/tree/master/examples/Unit/IMU_MPU6886

Only the second one has the issue described in this thread, the first one seems ok.

You are right, Unit IMU_MPU6886 is an external device, using external I2C.
