Convert sensored BLDC DRV8312 SW to be used with DRV8301
I'm converting the demo SW sensored BLDC DRV8312 so that it can used for the DRV8301. Until now I haven't succeed to make the buildlevel 4 work as expected.
Do you have at TI already a demo SW sensored BLDC for the DRV8301?
Finally I made again the migration more slowly from the sensorless SW to the sensored SW and now it works.
But I'm still interested in a more robust sensored SW for DRV8103 from TI !
I am glad you were successful in your port. Unfortunately, I know of no sensored code that was developed for the DRV8301 platform.

See attached for DRV8301 + F28035 + Sensored. Here is the readme
DRV8301 - Sensored BLDC
To compile correctly the BLDC_int folder can reside somewhere likeC:\ti\controlSUITE\development_kits\drv8301_dev (new folder)
Note that there is a bunch of non-used and mis-named code; this was built up from an InstaSPIN-BLDC project for a customer sensored demo in a day…it works, but it’s not something we would want to publish.
Instructions for demo:
Make sure:#define BUILDLEVEL LEVEL7in BLDC_Int-Settings.h
Make sure project/active build config is: F2803x_DRV8301_RAM
Build and load program to controlcard.Enable Real-time modeRunSet watch window to continous refresh

These speeds are for a custom motor, but very similar to the NEMA17 BLDC
