Add a piezo element for audio in Rev A HW

Open 57Bravo opened this issue 1 year ago • 2 comments

I was able to use a piezo element to get my beepberry to speak using espeak. It would be nice if the next rev of HW had a buzzer/piezo for indications and audio.

A little tinny, but it's usable.

Could you upload a schematic and a BOM to this request so that I could look into reproducing it? Pictures of hardware install would be great too.

Sure thing. I pushed the repo here.

I'll add some notes on the SW tonight. It's basically just using raspi-gpio to map GPIO to a pwm audio device. You can use anything that works with alsa. Play, ffmpeg, etc.
