Hi All,

I would like to know if anyone has written the MIDI class driver for this micro. TI have provided the CDC and HID class's but I would like to make a midi device using this chip .. I need to know howto interface a new class to the USB stack. I have the correct descriptors for this class.

Any help on doing this much appreciated. (I am implementing a drum trigger to MIDI interface ..)

Cheers,
Bernie

Don't worry. I have worked it out. Now have a working drum trigger -> usb interface that appears as a MIDI device to the PC.

I ended up hacking the HID class to implement the MIDI class.

The hardware is going to support 12 piezo trigger inputs and 10 digital to allow you to change samples on the fly.

I have it working with Hydrogen under Linux at present, but as it appears as a standard MIDI device, it should work in windows as well.
(It enumerates ok in WinXP)

Cheers,
Bernie
