Also, I have a favor. After execute function "M5.IMU.getAhrsData(&pitch,&roll,&yaw)", I can get about pitch:3, roll:10, yaw:random. I want to offset this pitch and roll within -180 to 180 phase. Could you fix it?

Menginventor commented 3 years ago

May be you need to implement AHRS update function by yourself. the AHRS (roll pitch yaw) system is define how imu frame rotate from global frame you can redefine imu frame by tranform them once with rotation matrix before assign to AHRS function.
