Other Parts Discussed in Thread: MOTORWARE, DRV8312
According to the spruhj1f-InstaSpin-UserGuide.pdf Section 5.2.6 , there is supposed to be a variable called USER_PWM_DBCNT_INIT_STATE in user.h that helps set the dead band time . Alas, I could not find such a variable in user.h in the latest Motorware motorware_1_01_00_13 . May be it was used in an older version of Motorware ?? Its so misleading especially for people who aren't the best at digging through OO software.
After digging into HAL_setParams => HAL_setupPwms => I found where the dead time was set for my drv8312 kit. It was the function PWM_setDeadBandOutputMode , but then it was set to PWM_DeadBandOutputMode_Bypass which seems to be no dead time. I didnt want to risk blow up my hardware so I diged in more and found
the functions in hal.c / hal.h
PWM_setDeadBandOutputMode
PWM_setDeadBandPolarity
PWM_setDeadBandRisingEdgeDelay
PWM_setDeadBandFallingEdgeDelay
to be my way to set the desired dead band. And the variables in hal.h
HAL_PWM_DBRED_CNT
HAL_PWM_DBFED_CNT
There should be an update to Section 5.2.6 of the spruhj1f-InstaSpin-UserGuide.pdf to make life easy for people who don't want to spend a month studying everything - code and documents.
