Good day! We have a new design with a DRV8301 being driven by an MSP430, and I seek clarification of how exactly the MSP430 PWMs should drive the DRV chip.
In the PDF that came with the demo code bundle, On Page 4 it shows a commutation for each state. I note that in this diagram, and the code, there's only one PWM operational at a time.
When I research online, I see many sources showing that there are TWO PWMs running at the same time, which makes sense to me as you need two coils to move the thing, (one to pull and one to push (but this is my first motor control project, so I might be wrong).
So, which is the RIGHT way? Does the DRV do something internally to drive the second necessary PWM, or is there no need to drive two at the same time? The demo code only drives a single PWM at a time.
All help greatly appreciated!
