'[EE]: Gameboy LCD to TV, how to?'

Hi!

Would it be possible to get the signals that drive the LCD display of a gameboy (not colour) and pass them to a PIC that will output a video signal ???

Well, I think it *can* be done, but how to start?

Thanks in advance,
Diego.

I doubt a PIC, or even a fast SX could handle this. A lot depends on
the order in which the GB scans the display, and the refresh rate.
Unless these happen to be very close to the required TV spec, this
will involve a dual-port display RAM buffer.
It would probably be much easier to use a cheap CMOS monochrome camera
pointed at the display (yes, seriously!).

A group at the SRS have been doing this for some time.  Check out
yahoogroups 68332ABB.  THey have a terminal program to transfer the images
from the GB cam to a MC683XX processor to a PC link.  They also have
routines that run in real time on bots that implement a low cost vision
system.

Good Luck
