Poof of Concept for Dynamic Marquee on Dual/Second LCD

[droogie]

Hi All

I have been playing around with an official 7" Pi LCD i bought at Xmas.

I have made a proof of concept for a dynamic Marquee, where the LCD will change systems when going through the menu and show marquess when loading the game.

Thanks to those who post on the boards as the scripts were very helpful
Im using the Arcade Game Centre theme which I like very much

i've uploaded a video of the Proof of Concept.  Hopefully one day there will be a PI LCD that would fit into my  Bartop Arcade Cabinet
Apologies for the quality of video

This is awesome! I really like that it displays game marquee when "in game".

Very awesome

Now all we need is it to change the side art and control panel art too. You know like all the futuristic TV shows we see.

But then again Back to the future II said we were going to have flying cars and hoverboards too..  lol

I was wondering if I could do this with my RPI and a gert VGA + hdmi with attractmode.
This tells me maybe I can.

I didn't think about VGA but that could be a good option.  I was thinking of something like the below Car Rear View Monitor LCD for a Bartop Arcade but I wouldn't pay that much and wonder if it could be adapted to VGA

Great work, and sorry for the late post.  I saw the video before actually finding this thread.  Any chance that you might share some details about how you implemented it?  Assuming that you modified the layout to use both screens and are pushing the artwork to the second screen, as well - but confirmation would at least point me in the direction I need to start investigating.

Had been using Hyperspin, and had this working through HyperMarquee, albeit to a split ultrawide for testing purposes.  Friend had turned me on to Attract-Mode, though, and I truly love it.  Have just been struggling to find any concrete path to take to accomplish this.

Thanks!

Care to share how you did this?

I would also appreciate any insight on this as well.

Thanks!

Hooping OP comes back because i've hit the limit of my current knowledge on dual screens with the RPI.

I hooked up my gert vga 666 to my rpi2 and did some research.
Looks likes the gert will just take the place of the official touchscreen display in op's video when hooked up.

It takes an application with a Dispmanx backend in order to use both screens simultaneously.
I found i can look at console or X on my HDMI monitor and send a video to the vga using.

omxplayer --display 4 video.mp4

I can also send a marquee graphic to the second screen using:
export VC_DISPLAY=4
./pngview -b 2 -l 3 19xx.png
it appears in the center of the screen.

Actually using export VC_DISPLAY=4 will send any dispmanx enabled app to the vga.
Including attractmode while leaving the hdmi a working desktop because it is also dispmanx app.

I'm also reading about a python framework that is dual screen aware / dispmanx called kivy.
it looks like people use it to create touch screen buttons to control other apps.
i'm thinking it can also throw out a simple image on a second screen.

This is what i put into config.txt to make my hdmi screen the default screen and vga second.
The monitor stays in sleep mode until you activate it by telling an app to use it if anyone was curious.

enable_dpi_lcd=1
display_default_lcd=0
