OverSoftNL Posted December 29, 2018 Share Posted December 29, 2018 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 with "Bally/Williams" underneath it (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've also tried it on my Stern (Whitestar) High Roller Casino, but that doesn't go past the logo either. I have a couple of other machines (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?

Content Provider lucky1 Posted December 30, 2018 Content Provider Share Posted December 30, 2018 Maybe you forgot to set the enhancer jumper on PCB ? Set it to 2-3 connected and set enhancer on in the pin2dmd firmware. Link to comment Share on other sites More sharing options...
OverSoftNL Posted December 30, 2018 Author Share Posted December 30, 2018 That was it! I didn't populate the pins, because i couldn't find anything about the "enh" pins in the documentation. I've added the pins and a jumper and it works now. Thanks for the help! I do see a little bit of static on the middle and bottom rows though. Could that be because of the long cable between display driver and PIN2DMD? Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted December 30, 2018 Content Provider Share Posted December 30, 2018 Yes, try to keep the connection between the panels and the controller as short as possible. Lowering the power supply voltage may also help. I set mine to 4.8V Link to comment Share on other sites More sharing options...
OverSoftNL Posted December 30, 2018 Author Share Posted December 30, 2018 Thanks, i'll try to pot it down a little bit and see if that helps. In a blue palette there's less static, so it could be both issues. Link to comment Share on other sites More sharing options...
