Hi

I've asked for help a few times, but there's no clear answer, so I'm asking you again 

I have a DRV2625 demo machine

I want to drive it by inputting the Square half wave into the vibration motor

International patents are currently being reviewed, and various experiments are required for this.
As far as I know, it is possible to input square and half waves with demo equipment.
Please tell me how to set it
