Problems with ST Motor Control Workbench [Copy link]

I want to configure a BLDC motor without Hall driver using ST Motor Control Workbench,

The upper and lower bridge arms are determined, how to configure the back EMF pin in the software? Thank you!

Is this the back EMF interface? Thank you

Found a statement that looks like a phase change

This is strange.

Is this the ADC input pin? Do you detect the three ADCs separately? You need to look at the schematic diagram. There are algorithms for single current detection and dual current detection.

The three currents are detected separately. The key is that the code generated by this software cannot be used directly, which is very annoying.

It should work, I tried his reference board and it worked.

Check to see if there is any difference between your own board and the reference board.

Thank you! I'll try it
