RE: BOOST-DRV8711: Reading BEMF voltage in EXSTALL mode

Hi Rick,

Thank you for your reply.

Regarding my question-3,
Is the following statement correct,
The BEMFn/STALLn is triggered at 90, 180, 270 and 360 degrees, and the BEMF voltage can only be read only at 90, 180, 270 and 360 degrees of the current coil waveform (when BEMFn is pulled LOW) in external stall configuration.

I am using 1/4 microstepping and SMPLTH at 100usec,
What should be the range of STEP frequency (in kHz) inorder to detect the STALL?

Thank you!

Kind Regards,
Sagar Kunder
