Convert sensored BLDC DRV8312 SW to be used with 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 !

Frank,

I am glad you were successful in your port.  Unfortunately, I know of no sensored code that was developed for the DRV8301 platform.

Frank,

See attached for DRV8301 + F28035 + Sensored. Here is the readme

DRV8301 - Sensored BLDC

2011-12-12

To compile correctly the BLDC_int folder can reside somewhere like
C:\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 LEVEL7
in BLDC_Int-Settings.h

Make sure project/active build config is: F2803x_DRV8301_RAM

Build and load program to controlcard.
Enable Real-time mode
Run
Set watch window to continous refresh

Add to watch window:

EnableFlag -- Set this to 1 to get motor control started
BackTicker -- This will increment to let you know the program is running
hallCommutateFlag -- Set this to 1 to change from force-commutate to speed-control
SpeedRef -- This is the target speed (in normalized to speed of 5000rpm)
(speed1).Speed -- This is the speed reading (from the speed macro, in nomrmalized pu)
(speed1).SpeedRpm -- This is the speed reading (in RPM)

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

Speed (RPM) Speed (pu)
1200 0.24
1800 0.36
2500 0.50
2700 0.54
3300 0.66
