Press the user button for calibration before any operation.  I should have copied the manual in the repository on the project. You can find it here : https://github.com/pat92fr/FOC2

Turning it off, then on, then pressing the button does nothing it seems...

Pole Pairs is saved (correctly) to 12, motor current limited to 2.6A

Not only is there no motor movement when pressing the button (anywhere from a quick click to 1 second and inbetween) but there is no change in drawn current. Supplying it with 12VDC.

Thank you. See git : https://github.com/pat92fr/BrushlessServoController/tree/main/03-Firmware/03-BETA

You will find binaray, GUI and a few motor settings.

Let me know if that works for you.

Patrick.

Hey! Thanks for getting back to me :)

I managed to get the FW up onto it, and i can get 'a reaction' (motor does some movement, and can apply a torque in a random direction) How do you set the synchro offset etc? I want to get it to the point I can actually move it. I've set the poles correctly, etc.

Hey!

Awesome work on this!

When do you anticipate dropping the FW for the AS5600 + B-G431B-ESC1 board? I've got some hardware to hand now and would love to give it a go :)
