    USB MIDI Jack Configuration

    content.librarian

      Hello folks,

         

      I've been working on getting a modified version of the USB MIDI 2x2 example project up and running. My goal as of right now is to simply add an addition port to make it a 3x3 MIDI interface with both an internal and external connection.

         

      So my main issue is the lack of documentation on configuration of the MIDI IN/OUT jacks in the USB macro. The component datasheet gives lots of good info on the descriptors and other USB configuration setting but almost nothing on the MIDI Jack configuration.  

         

      Here are the parameters i'm talking about

         

      bJack Type - This is simple, EXTERNAL, EMBEDED, or UNDEFINED

         

      bJackID - Also straight foreword, ID for each jack in the design 

         

      bNrInputPins - Have no idea what this parameter is for

         

      baSourceID - No clue on this parameter either

         

      baSourcePin - No idea on this guy either

         

      iJack - The String name for the jack

         

      Can one of you smart folks shed some light on what each of these parameters is for so that I can configure it properly?

         

      Thanks!
