DynamicMarquee with Pi5 and a zero

LeatherWing

I bought a Pi5 and a uws display at the same time. To my chagrin I found the DynamicMarquee2 did not work under bookworm.

Without waiting for new applications to be developed with the ability to throw an image out the hdmi port I wrote a script to just have another raspberrypi display the image via wifi. That way I didn't need to fish a long cable from top to bottom of my arcade cab. I use 0 clock cycles to keep the display running while playing a game, and eventually could add video marquees with no cpu load while playing as well. Figure this should work for those still running a pi3 that want a dynamic marquee.

The script and setup instructions can be found on github

Hey, nice project - looks cool ! Is that Attract-Mode running ?

LeatherWing

@mitu thank you! I appreciate the feedback.

Yes that's attract mode running my marquee plugin. I've done a little to code for emulationstattion as well, but that side is still very clunky at best.

Now running from emulationstattion.

Hi Bud. I've followed your instructions to install the scripts on both the Zero 2W and Pi5, copied all the images as per the instructions, and both devices are communicating with each other over SSH.

Great, except, the Zero 2W just sits there at the cmd prompt and displays the boot text. What am I missing from your instructions? The images aren't appearing when selecting a game?

After a little more digging, I've come across 2 issues:

When the zero 2w boots, it comes up with the error 'sudo: /home/pi/t.sh: command not found' yet ts.sh is in the /home/pi/ directory:

This is in attempt at adding a default image as per:

'if you want a default image on boot use 'sudo nano .bashrc' and add this to the last line: (rquires autologin to be set in raspi-config)

    sudo ~/t.sh retropie.png'

If I remove that line from 'sudo nano .bashrc' then obviously the error no longer appears.

In the t.sh file, theres two instances of 'pi@retrocade.local' should these not be 'pi@retropie.local' as thats the host name of my Retropie setup. I have changed these two to be 'pi@retropie.local' instead, but that made no difference so am assuming the issue is to do with point 1 above:

Out of curisoty, which OS was this script designed for on the zero 2W?

Is there anyone you could chip in with this? I've bought the screen and zero pi 2w and would like to get it working if possible?
