I am using M5Stack Core2 and Arduino IDE 1.8.16 on windows 10 and MAC. Compiler has many errors. So I could not go through them.

Then I downgrade Arduino IDE 1.8.16 to 1.8.15. It works well.

Is this know and common problem?

@m5stack
Thank you. Now it works.

Hi, I purchase M5Stack Gray recently and trying to read IMU with sketch example M5Stack -> Basics -> IMU.

However value of yaw decreasing until -180deg and then jump to 180deg even M5Stack gray unit sits on my desk. It continues to move. by time by time.

I use
ARDUINO IDE 1.8.15
M5Stack library 0.3.1

and header pat of sketch is

// define must ahead #include <M5Stack.h>
#define M5STACK_MPU6886
// #define M5STACK_MPU9250
// #define M5STACK_MPU6050
// #define M5STACK_200Q

#include <M5Stack.h>
