ZeDMD finding but not loading images #5

Open wesbeyrent opened 1 month ago

wesbeyrent commented 1 month ago

I installed Marquee Manager through RetroBat menus and have confirmed that it is installed. Renamed config-dmd.ini to config.ini and set the proper location to dmd.exe. However, I am just getting the ZeDMD logo flashing in my marquee when the script calls to change the image.

I have checked the ESEvents.log and see that it is finding the marquee.png files in the mame\images folder, but they do not display.

I noticed the loadfile command has double slashes in the path. Not sure if that is the issue: INFO:root:Executing the command : echo loadfile "C:\RetroBat\roms\fbneo\images\jpark-marquee.png" replace>\.\pipe\dmd-pipe

ESEvents.log

Nelfe80 commented 1 month ago

Hi, I'd need the valid url of an image and the line in the log that it found it, with an example. Thanks for your help.

wesbeyrent commented 1 month ago

It's line 117817 of the original attached log file.
Valid URL to that image from screenscraper.fr = https://screenscraper.fr/image.php?plateformid=157&gameid=40060&media=wheel&hd=0&region=wor&num=&version=&maxwidth=338&maxheight=190

Nelfe80 commented 1 month ago

Sorry, but for reasons of time, I'd just like you to give me a local link (path) to a working image (in your local system) and the corresponding line in the log file provided.

wesbeyrent commented 1 month ago

Ah. Got it. Here you go:

INFO:root:###FF File found : C:\RetroBat\roms\mame\images\arkanoid-marquee.png >> Convert to marquee size PNG INFO:root:Executing the command : echo loadfile "C:\RetroBat\roms\mame\images\arkanoid-marquee-topper.png" replace>\.\pipe\dmd-pipe

Local file path: "C:\RetroBat\roms\mame\images\arkanoid-marquee-topper.png"

(edit: attaching the generated png for reference) arkanoid-marquee-topper

Nelfe80 commented 1 month ago

Thanks. So the file C:\RetroBat\roms\mame\images\arkanoid-marquee-topper.png exists on your hard disk? Please send me your config.ini Test if process dmd is working : in a cmd : tasklist /FI "IMAGENAME eq dmd.exe" in powershell : Get-Process dmd

wesbeyrent commented 1 month ago

I ran both. Here are the outputs:

wesbeyrent commented 1 month ago

Forgot to answer your question.

So the file C:\RetroBat\roms\mame\images\arkanoid-marquee-topper.png exists on your hard disk?

Yes, the file exists on my hard disk. That's the arkanoid logo I attached.

I also initially tried with auto generate turned off, and it found the previously scraped arkanoid-marquee.png file, but didn't display that either.

Nelfe80 commented 1 month ago

How do you flash your Zedmd ? What is the firmware version ?

wesbeyrent commented 1 month ago

I used the ZeDMD updater for windows to flash it last. The updater tool currently finds it as COM11: ZeDMD v3.6.0.

The device shows up as USB-SERIAL CH340 (COM11) in windows device manager. I tried changing the bitrate from 9600 to 128000 bits per second, but it didn't change anything. Let me know if there is a specific setting that is required for the device to communicate.

Also, the DMD currently just displays 3.6.0 in the bottom right corner after showing the ZeDMD logo and then the PPUC notice/logo after booting.

Nelfe80 commented 1 month ago

Please kill dmd.exe and launch dmd.exe in a terminal cmd or a powershell. Read and check if dmd.exe find your com port and baudrate.

wesbeyrent commented 1 month ago

Interesting. If I run it from the Command Prompt or PowerShell, I get this:

Failed to load DLL: Failed to load dynlib/dll 'dmd\\zedmd.dll'. Most likely this dynlib/dll was not found when the application was frozen. Traceback (most recent call last): File "dmd.py", line 568, in <module> AttributeError: 'ZeDMD' object has no attribute 'enable_debug' [12636] Failed to execute script 'dmd' due to unhandled exception!

dedmd.dll is located in the same folder as dmd.exe where I'm running it from.

Nelfe80 commented 1 month ago

sorry, you need to run dmd.exe from the parent directory. So you need to go to the /Marquee-Manager/ folder and launch dmd.exe with /dmd/dmd.exe cmd : dmd\dmd.exe powershell : ./dmd/dmd.exe

No problem. I've updated dmd.exe on the git, try it please. Which system are you on? 64 or 32? Which version of Windows?

wesbeyrent commented 1 month ago

64-bit Windows 11 Pro

Nelfe80 commented 1 month ago

Just like me. Have you tested the new dmd.exe?

wesbeyrent commented 1 month ago

I did. I'm getting the same exception, just new line numbers. Here's the end of it:

Nelfe80 commented 1 month ago

What about the ZeDMD instance in your log? In mine, it says “ZeDMD instance created: <main.LP_ZeDMD object at 0x07F687C0>”

wesbeyrent commented 1 month ago

What log file is that? I only have ESEvents.log. No mention of the word "instance" in it. No logs in the dmd folder.

edit: Figured it out. Here's my line: ZeDMD instance created: <main.LP_ZeDMD object at 0x07BA96E8>

wesbeyrent commented 1 month ago

Also, is there any way to specify the port? It’s getting hung up connected to something on COM2 (I think a Sinden Lightgun) but I need it to use COM11.

wesbeyrent commented 1 month ago

update: I unplugged the 2 Sinden guns to avoid the false connection to one of their COM ports, and it gets through to the exception again. As you can see in the full log below, it is creating the instance: ZeDMD instance created: <__main__.LP_ZeDMD object at 0x083C96E8>

Nelfe80 commented 1 month ago

I don't think it's a port problem. You can try changing the com port in windows settings. You can also try putting an older firmware in zedmd updater to test. Then it's a memory access problem, as if the program can't access part of the ESP32 module's memory... You can also try renaming zedmd64.dll to zedmd.dll to check whether it detects your system. You may also need to rename the other 64 files without the 64.

Ok. Before launch /dmd/dmd.exe, kill all dmd.exe process with "taskkill /IM dmd.exe /F" in cmd Then launch /dmd/dmd.exe else "CreateNamedPipe error: (231, 'CreateNamedPipe', 'All pipe instances are busy.')" or "Acces is denied" or "Busy" state.

It says ERROR: The process "dmd.exe" not found.

I did try renaming the dll and lib files by removing the 64 from the filename, but it threw a dll error, so I renamed them back. Apparently it's loading the 32bit dll files?

Sorry, I don't know why there's a problem. Try reflashing the dmd with the latest version and redoing this to see what it displays. There's no reason why it can't connect to the dmd...

So strange. I updated back to 3.6.0 and am receiving the exception error again.

I'm wondering, though. My ESP is wi-fi enabled, but I haven't tried flashing the 3.6.0 WiFi version. Maybe I'll give that a shot instead of relying on USB. If I flash the WiFi image, will I still be able to use it via USB?

Maybe. You're welcome to try. I've never tried it but I guess it will still work on usb.

I think it may be related to https://github.com/freezy/dmd-extensions/issues/460 for me. I tried flashing the WiFi-based image, but couldn't figure out how to get it set up, so I'm just relying on the USB connection. I did get the dmdext command to display the test image successfully with dmdext play -d zedmd when I used version 2.2.0 beta2, but I don't have the tech skills to fork your repo and build it using freezy's older beta code.
