I've built a PIN2DMD v3.1 shield and connected it to a STM32F4 Discovery board.
I've activated it and it works without flaws on Visual Pinball and VPinMame.
The input test runs without problems (pin 1,3,5,7 and 11 show when they're shorted to ground).
There is a SD card in there which works properly (updated the firmware from it), but i have no custom colorizations on it yet.
Now i'm trying to put it in my STTNG machine, but it doesn't seem to get any input.
It's set to Bally/Williams input, the latest firmware is installed and i've tried both with enhancer and without, but it doesn't show anything other than the logo (see photo).
I've tried a different ribbon cable between the machine and the PIN2DMD and i've tried turning it on before and after the machine, but it doesn't show anything other than this. (When i connect to original DMD, the display works fine)
I have a couple of different machines (a Stern Whitestar and a couple of WPC and WPC95's), but haven't tried the others yet.
Does anybody have any ideas on how to get the display up and running?
