Anyone had luck writing serial data out of the USB port on the ADuC-MT7020?
I'm using the Keil (demo) Compiler and the ARMWSD to program.
I get the DAC and GPIO working, but can't figure out how to write serial out the USB port. I'm also trying to write to the LCD.

I don't know much about ARMs, but i have worked with the Keil Demo using a C505C for a class I took. If you're using driver files for the USB and LCD functions, watch how much HEX or BIN code you're generating. I believe Keil Demo will only generate 1024 instructions before outputting a blank file. I also don't remember whether it'll tell you the demo limit has been reached.
