Hello there!

Today I've been busy building an VGA-SCART cable for my OCM (the Altera DE1 with CARO & HRA! core).
I've followed the instructions here:

www.idiots.org.uk/vga_rgb_scart/images/pinout.gif

www.idiots.org.uk/vga_rgb_scart/images/cable_wiring.gif

but my LCD and CRT TV's just display some white screen with black lines. I've OF COURSE configured the OCM to output at 15HZ mode. Shouldn't that scheme work?

Thanks!!

I made mine with the next schematic and it works fine:

VGA ------ SCART

1 --------- 15
2 --------- 11
3 --------- 7
13 --------- 20
14 --------- 6
10 --------- 17
9 --------- 16

As I see it,

1,2,3,10,13 VGA pins are connected in the same way in both vanfanel's and EVPON's cables, but

vanfanel also has 6->13, 7->9, 8->5 connections, and instead of those three EVPON has just the following two: 14->6 and 9->16

Damn, I just can't make it work! I am useless at soldering because I've got souch a BAD pulse...
Do you know where can I buy a cable like this, already made and ready for use?
