I saw on the main buglabs page that v1 will only have a piezo buzzer and v2 will have ‘proper’ audio. So for v1, what sort of API are you planning on exposing? For piezo you’re pretty limited, but you could go from just something simple like ‘doBeep’, to exposing some tonal stuff that does it via PCM (assuming the buzzer is on PCM output GPIOs on your board). If you have PCM you can go as far as ‘playNote(x)’.
Just curious which way you guys were leaning.
