PCM2707 HID status write

Dear All.

I can write HID status by SPI interface and windows get the HID command.

But the status bit does not clear automatically and windows get repeated commands so much.

What duration ( ms or us) is required for sending only one HID command to OS before clearing the HID status bit.

Thanks and best regards,

Kevin.

    Hi Kevin!

    I also noticed that the status bits need be cleared or else it will be repeated to the host.

    I wait approximately 50 ms before clearing and I've never seen a repeat. You can probably experiment with this to find a minimum interval but actual recommendations is bound to be found in the USB HID device specification. I haven't read it but it's probably a really large document...

    Good luck with project!
