Nintendo DS TV Out (Homemade ?)

[Moosmann]

I take a look inside a old Nintendo DS:



The digital color bits are marked ad LDR0-LDR5, LDG0-LDG5 and LDB0-LDB5.
Note: You find LDG3 and LDG5 on the left/down side from the pcb.
The problem is to find the composite sync signal and the clock signal. But I think, it is possible to get a RGB (TV out) with the same circuit schematics like the TV Out from Sega Game Gear or the 3DO RGB Mod.

BTW:  I found this:

A homemade DS TV adaptor ist much funny and cheaper.

I've been looking the same info, I might have something that could help.

"quote from the website"

The closest match I could find to the DS LCD is Sharp LQ030B7DD01. You can find a datasheet Here. Aside from RGB, the only LCD signals I needed to use were DCLK1 and GSP1 (everything is conveniently labeled on the DS PCB). GSP1 is vsync, analogous to SPS in the datasheet. I find hsync by counting clocks (263 per line). If you need the actual hsync signal from the DS, you'll have to find it yourself; I don't know which one it is. The bottom screen data is latched on rising clock edges, top screen is read on the falling clock. I had to buffer a full frame in ram because screen timings didn't quite match up (incidentally, this also made adding the screen capture ability very easy).


any help?

What more information do you need? Use your oscilloscope or frequency counter to check DCLK1. If the frequency matches the one you calculate then that's the one.

Are you sure the internal LCD runs with TV timing?
