    • [Solved]Doesn't work sample sketch "MP9250BasicAHRS" on M5Stack Gray

      Hi,

      I bought M5Stack Gray for motion sencing of wheelchair.

      I installed M5Stack library and sketched on my Mac and basic sketch worked fine.
      Also I tried to install sample sketch "MP9250BasicAHRS", but it didn't.

      • comple and download into M5Stack was work fine
      • Then I checked behavior of M5Stack via Serial Monitor and following message was displayed.

      MPU9250 I AM 0 I should be 71
      MPU9250 is online...

      It look like that MPU9250 didn't calibrate.
      Is this following line correct?

      // Calibrate gyro and accelerometers, load biases in bias registers
      IMU.calibrateMPU9250(IMU.gyroBias, IMU.accelBias);

      I've no idea to fix this problem and will you help or give advises?

      Thank you,
