PSP as external LCD

I have posted this on other forums as well and was finally told to try here.

I had a thought the other night while re-wiring a 2x16 serial LCD. Would it be possible to write a homebrew program that would be able to communicate with programs like LCDsmartie http://lcdsmartie.sourceforge.net/ through USB and then display the sent data on the PSP's screen.

Since I am not a programmer and have no experience I am wondering if a homebrew app like this is even possible.

Thanks

It might be possible via usb, but try to use the sio. Its a bit better, and you can make your own driver to do those things.

It's very possible, and easy with the serial port.
You'll have no interface at the PSP end to emulate the 4/8 bit interface of the
Hitachi controller LCD screens, but serial LCDs would be easy to emulate.
