Communicating with Clip+ over JTAG while its running
« on: October 22, 2011, 12:02:27 PM »
I'm pondering a project where I hook up a microcontroller to talk to the Clip+ while its running.
It has a JTAG port, but I don't know much about JTAG.

Would it be possible to send/receive info on this bus while the player is running?

I'm thinking of hooking up a big 20x4 Character LCD to it.
