I actually do think that the OP should get a real answer. It doesn't seem like a student request, and if this forum cannot help such a simple request, then that is kind of sad.

I don't do NXP, so I won't spend the time to answer the OP, but I'm sure that some readers have dealt with the LPC2378 family.

Please post it if you've got it. I'd like to see it too.
