Hi team,

Could you advise if I can generate the half-wave like below using the beep generation register below?

Hi Shinji,

Unfortunately I don't think this waveform shape can be recreated using the beep generator.

Hi Ivan,

Beep generator generate full sin/cos wave unit and there is no way to send only 1 half wave?

I don't need to repeat this half wave, but only 1 half wave pulse.

Could you double confirm if that is not possible?

Hi Shinji,

Further development would be needed for such case, currently the calculator used to generate the coefficients is not configurable for such waveform.
You could try by manually setting the coefficients directly to the registers, but this is not something we have tried before.
