CCS/DRV8312-C2-KIT: How to program rotational speed using CCS

user5987472

Part Number: DRV8312-C2-KIT
Other Parts Discussed in Thread: INSTASPIN-BLDC

Tool/software: Code Composer Studio

Constant rotation can be realized with InstaSPIN-BLDC, but how can the following rotation be realized.

Switch the rpm every cycle without sensor (For example : Switch from 1000 to 3000 rpm in 0.5 second cycle).

I think programming in CCS is necessary, but I do not know how to use it. Please let me know if there are any documents or solutions.

Surely you have to write code inside the MainISR(void) BUILD LEVEL == 8 to modify the SpeedRef variable every 0.5s.

You can use a counter and use ISR time period for counter's timebase.

As Prabhjot replied, you might add some codes to change the reference speed every 0.5s using a counter based on the ISR timer.
