FOC sensing returns R=0 #33

Open bluesquall opened 5 years ago

bluesquall commented 5 years ago

Starting with VESC tool version 1.09 (on linux), I'm having trouble with the FOC section to detect and calculate parameters. It keeps leaving R=0, but gives a value for L. I can't manually enter an R value with the detection tool.

This is a small hobby motor (Turnigy DST-1200) that worked ok with VESC tool version 1.08 on windows. I'll go back to that version and see if I can do the sensor detection again.

As a side note, it would be nice if the git repo had tags corresponding to tool and/or firmware release numbers (e.g., 61908a5d5ea12ee3452c072d22bce7a51fcefa60 for tool v1.08).

Got it running with 1.08 again, then updated to 1.09 -- this time I tried with the wizard initially, instead of the buttons at the bottom section of the FOC window, and it worked like a charm.

Looks like it still fails with R=0 if you start over from the FOC window, but works fine if you start from the wizard. I'm not sure what the difference is in the implementation between the two approaches.
