HP Prime BEEPER.

Can all this HID and i2c be combined with Grove?

The tone generation is done with the Arduino currently, and I would like for the Prime to do it, it definitely has the processing power, although, I'm not sure thhat HPPPL would allow it, as some of the notes may need to turn the speaker on and off every 100 microseconds. I'm not sure HPPPL can allow commands so fast. I send the byte list of Tone Values via USBSend() - yes.

I will definitely share the code used, once I have tidied it up a bit, maybe later next week.

I do not know what Grove is, let me know what it is and I will answer your question :-).
