SH200I test strange results

[vvs551]

Why there are always gyro results the same in any static position of m5stick?

@vvs551 Hi, thank you for your question.

It is normal.
The gyro sensor detects angular velocity. so if M5StickC is not rotating, gyro value also not change.

@salty_good why such values? What does it mean?

@vvs551 sorry, I didn't understand your mean.

You mean M5StickC need to be (x, y, z) = (0, 0, 0) in any static position?
Because it's no calibration in the test code now...

@salty_good Thank you! I understand
I have not met before the calibration requirements for i2c digital sensors)
Sorry

[salty_good]

@vvs551 so sorry...
We will provide calibrated version code in the future!!

@salty_good Could you propose any idea how to calibrate data and get real time angle monitoring sketch?
Because there is a terrible fluctuations from the meaning value in the time.
I could not get something near zero in static position if I do accumulative addition like here:
gyroX += ((float)gX * M5.IMU.gRes - gyroX0);
Where gX - int16_t current gyro value, gyroX0 - float calibration value with gRes, and gyroX - float accumulative angle value

@salty_good Is there a calibration yet? Any update?
Thanks
