There is a word Press Y to run calibration, which can be used to automatically debug a set value suitable for the current device. After pressing the capital Y in the serial window, the knob will be rotated automatically, and after a while, the following result will be output in the serial port:

1
RESULTS:
2
    zero electric angle: 4.43 // The values on this side may be different for each device.
3
    direction: CW
4
    pole pairs: 7

Open motor_task.cpp file:

1
float zero_electric_offset = 4.43; // Replace the value with the value of zero electric angle output above.

After saving, write the firmware again. It should run successfully.
