DRV2700EVM: About "Note Generator and Simple Piano" function of GUI tool

Hiroaki Masumoto

Part Number: DRV2700EVM
Other Parts Discussed in Thread: DRV2667

Dear Support team,

My customer will use DRV2700EVM in their application.
But neither they nor I own the DRV2700EVM yet.

Can I create a 60 Hz sine wave input waveform using the "Note Generator and Simple Piano" function of the GUI tool?
What kind of input waveform is it?

Is the onboard MSP 430 capable of generating only differential PWM signals?
In this case, can I transmit to the DRV 2700 as a sine wave via a low pass filter?

Best Regards,
Hiroaki Masumoto

Hi Hiroaki,

My apologies for missing this post.
Yes, the above is possible with the EVM. It is a PWM signal through LPF. You can also provide external input through LPF if needed.
Alternatively, the DRV2667 has a waveform generator in Haptic Control Console that will use the internal waveform generator to create sine waves.
