I am new to hardware design and learning a lot as I go. I have been able to take the device-to-device demo (from DemoLab, document DOC-333917, posted by Jordi Jofre and updated by Richard Schmidmaier) and do some pretty cool things with it. I do have a question, which might be elementary but I'll only learn by asking (and I can't find an answer to which makes me think I'm missing something fundamental).
Will the spinning disc component still work if the external crystal was removed from the LPC11U24? From what I understand, the crystal is only needed with LPC11U24 for USB communication, but this application does not use USB. Can the chip's 12MHz IRC be used instead?
