Maybe we should refactor this anyway to make it easier for the real pinball machine. E.g. just one file with stern or WPC mode and all colorizing settings

 

 

If two files are already to much, the problem can´t be the software

This has to be fixed by documentation. 

If something needs to be refactored you should not only think about

two usecases. We should keep the files the same, no matter which use case

they are for. The palettes.dat file is already working that way.

Positive proof of concept for 192x64 pixel display size. Timing is working for that resolution

without flickering. Memory is getting low but still o.k.

Well, found the cause of the glitching, noise in the line. I'm going to try a shielded cable. I tried resistors, but that did not filter it out.

hello

 

I think that you are a friend from curbfeeler ;)

 

So the header just shipped today.

The other ones are in NJ... my bad. sorry. :unsure:

 

I have simular problems when the ribbon cable is conencted to the displays but not to the shield and someone touch the cable

or when the STm Controller is not 1000% connected to the headers (during my tests from the completed boards).

Just wait till Thursday (USPS says they should be there till 12-17-2015) and solder all together and try it again.

 

!!! And be sure that you solder 100% from the 100 pins !!!

 

I'm sure that the problems comes from the "flying" wires.

Thanks for the reply! 

 

Yes, I'm friends with curbfeeler! We are having a blast working on these!

 

I'll give that a try when the part gets here. It's such a relief knowing what the issue is now  :)

 

I did try wrapping the cord around a ferrite toroid, but unfortunately it didn't have any effect on it.

Since I can´t reproduce such effects on my WPC machines I´m a bit stuck here.

I did some research and found this

Maybe it helps. A shielded cable is a good start anyways. I would use a shielded Cat7 cable with 100ohm resistors.

What happens if you use a ribbon cable as short as possible to connect to the WPC/Stern board ? Is it getting better ?

NEWS flash :D

Rev 1.3 double HUB75 shields are in my hands....

bad side... I wait for a delivery of 16 Pin-Headers.

There was just one set left, so I soldered the WHITE Christmas Edition to test everything....
and YEAH it works fine (with my 2 display halves)

Video with the X-Files 3.03 (I think thats my fav test rom :wub:  )

I just had a look at a Stern DMD and it has a 220 ohms resistor in line and a capacitor to ground

in every signal line. I can´t read the value of the capacitor but I would bet on 33pf or 100pf.

Maybe that helps to reduce the noise.

1. Connect your Interface to PC and power on with SD Card removed . (red LED should be on)

2. Put in SD Card

3. Start PIN2DMD.exe and either configure in WPC or in Stern mode.

4. Save config (red LED going off)

5. Remove SD Card and Copy palettes.dat file generated with PIN2DMD editor to SD Card.

6. Put card back into interface

7. Connect to pinball machine and power on (red LED off, blue LED flashing when pinball machine on)

 

still the same problem

 

as I do to save settings the pin2dmd.exe, turn on the game pops up the message "pin2dmd not found"

Maybe, if you have 2 pin2dmd devices in your devices manager, one or both with a yellow exclamation mark then it's mostly a driver issue. Do you have win10 installed?

Restart Windows 10 with pressed shift key, then go to advanced options, allow installing of unsigned drivers. After that you are able to install the driver ;)

That's the only possible solution I know with win 10.

I think Installation with Zadig is also working (libusb-win32 1.2.6)

After saving the settings in pin2dmd.exe,

  the SD card should be saved pin2dmd.dat file ??

because on my sd card will not save
