UI flow IMU issues

[m5-docs]

@hetzer Yes, It need to be calibrated after device initialization.

[hetzer]

Is there a custom block for calibration. I like to use uiflow and prefer not to go back to arduino.

[m5-docs]

@hetzer Sorry about that I have asked engineer. He said that we'll not add this calibrated function block.

[hetzer]

Is it possible to get to gyro code coming with the firmware. I can see the the dafult gyro app is working accurately but all my get x and get y block resulting random numbers

[m5-docs]

@hetzer Are you sure that it is random data?

[hetzer]

Yes, en each start, while the unit is on the same position I get different values for x and y.
Z starts from zero and just increases in each measurement.

I tried to write a code to subtract the initial value from zero to calibrate but next x and y values within loop again starts from random values.

[hetzer]

Still no solution to this problem, the demo is working flawlessly but get_x, get?y and get_z provide wrong results. Can anyone help?

@hetzer Hi, thanks for your feedback, the block naming on IMU is misleading. get-x get-y get-z actually is Yaw, Pitch, Roll.

@liushasha said in UI flow IMU issues:

I am aware but still the pitch and roll randomly varies around +-10 degrees and the roll value increase over time exceeding 360

[hetzer]

Managed to get some more accurate x and ydegrees.
Is it possible to get yaw heading with uiflow?

if only use mpu6050,i try fix yaw offset， but Failed .....
