Pi 4 Dynamic Marquee using secondary HDMI output

petrisi

Hello,

I took an inspiration from PieMarquee2 and created a script which utilized Skyscraper cache for live marquees on the second display, so that you only need to scrape once and both the retropie and marquee will use the same data.

Also the omxiv-marquee was flickering on my cabinet, so I modified the mechanism a bit how the image data is transferred from the script to omxiv and it seems to work quite nicely now without killing and restarting the viewer.

If anyone is still interested in this (utilizing Skyscraper resources), please let me know and I can package these and write short instructions how to use - should these scripts work for you as well.

Thanks.

@petrisi i would love to use what you have please!
i have been trying to get the LCD panels working using a Adafruit RGB hat and failing...im no coder and only got a pi 2 months ago so its all new lots of errors but im learning!

I have managed to get the great work by Losernator working on a second screen but the screens are expensive.

Having a RGB hat and 2 32x64 panels cost less that $50 :-)

Im hoping someone on this forum can maybe add to the work Losernator has done and add support for the RGB Hat?
or even @losernator Losernator can chime in? :-)

Im happy to put to work in if people can guide? ill even donate a rgb hat and screen?

thanks in advance for any help

I’ve installed following the instructions - everything’s there - but no marquees show on the second monitor.

Can anyone tell me how i even begin to start troubleshooting?

My second screen is definitely working, i see loading screens - but just remains blank where there should be a marquee - i don’t even know where to start…

@losernator - I'm running into a few really strange things I can't figure out with the script. Hoping you can help.

I'm running a Pi4 on a 15.6" 1080P monitor with a VDSDISPLAY 14.9 for a marquee. I'm using the most recent script on your github.

Issue 1: When I run a rom - my main monitor displays a videoloadingscreen - the marquee changes from default.png to the marquee image. But when the videoloadingscreen ends and the rom boots - the marquee flashes back to default.png and then back to the marquee image.

Issue 2: Daphne, Dreamcast, OpenBor don't actually display marquee images for some reason. All the files are present in pi/PieMarquee2/marquee/ (appropriate folder) but they don't display at all - just stay on the default.png

Issue 3: When my marquee is plugged into the Pi4 - the command line text on my main monitor is vertically squished. I've tried both

fbset -fb /dev/fb0 -g 1280 720 1280 720 16

and

fbset -fb /dev/fb0 -g 1920 1080 1920 1080 16

in my autostart.sh - but neither make a difference.

Help? Anyone?

I'm in the process of building a new dual monitor arcade cab and found his new revisions a lot simpler to get setup with both PNG and MP4 files.. .
