Bug? uiFlow 1.4.5 Stick C IMU ypr[] (getX and getY) values are weird.

[liemph]

I tried to get the roll, pitch, and yaw (ypr[]) of Stick-C IMU using uiFlow 1.4.5 (and 1.4.5.1) but the values seemed weird. X( ypr[1]) and Y (ypr[2]) are decreasing from time to time until the variables getting overflowed. I have checked my IMU using C++ (Ardunio IDE) and all were OK.

raw_x = None
raw_y = None



raw_x = 0
raw_y = 0
while True:
  raw_x = imu0.ypr[1]
  raw_y = imu0.ypr[2]
  label0.setText(str(raw_x))
  label1.setText(str(raw_y))
  wait(1)
  wait_ms(2)

@liemph thank you feedback . you could delete wait block to solve it. our engineer will fix it later .

Hi, the problem is still there. Removing the wait block kinda of fix it but reading are inconsistent. Any fix?

Thanks

@ipodlux For the time being, I stopped using uiFlow (or Python) for IMU related project. It is not reliable and it is slow. Use Arduino IDE, you will have a much faster code and reliable result.
