MiSTer FPGA Forum

awesome! glad what i've made isn't totally UN-reproduceable! i have CAD for a desktop frame that i will upload to the github. i haven't had a chance to test print it yet but i will put both the fusion files and the STL so if anyone wants to try it out then please have at it!

edit: i have uploaded my CAD and the 3MF files for the parts to the github. this frame assumes you have a sheet of 3mm thick LED diffusing acrylic cut to the correct dimensions (326mm x 86mm) to sit just in front of the matrices. see the CAD for details.

Thanks for the great project! I recently built one as well. I wanted my display a bit away from the actual MiSTer so I wrote a version that sends the GIF over HTTP.

holy crap that rules! i will have to try your setup out!

I got my led panels Today and the ESP32 is on the way

Finished my build with SD Card support. The DE10-Nano original power supply and SD Card worked perfectly for the build.

This looks awesome, great job!

This looks fab! I couldn't compile one of your previous builds (admittedly I didn't try very hard to resolve the issue) but I'll defo give it another shot now. This is incredible thanks!

Got it to compile, was missing some libraries not mentioned in your readme and LED_BUILTIN wasn't defined for my particular dev module so just defined the pin manually. I'm getting communication on the serial monitor so presumably it's ready to rock.

By some stroke of luck the plexiglass I'm intending to mount this on appeared today so when I can get at the cabinet with the MiSTer I'll give that a shot. Might have to wait until after the weekend but I'll get some images.

Did you use the trinity board?

Initially I used a ESP32 S2 I had laying around, I'm now using a Trinity board.

Could Someone show the wiring on the back of the panels. I have an ESP32 Matrix Shield (Mini 32) bur cant work out what to connect to what. The Circuit board connects directly to the left most Input, but then covers the power supply and do I need to loop back to the shield ?

Thanks

Hopefully this is helpful.

You need to wire up a barrel jack to the 5V red/black screw terminals.

Hello, could someone tell me what option I need to choose here? I'm trying to flash my module, an ESP32 Trinity, but in MISTer it doesn't give me that option.

That‘s the update for the tty2oled firmware.

Cancel this and disable the option in the ini file.
Howto is given on matrix github page.

The Matrix Github tells me to follow the instructions to configure the tty2oled as the first step. I'm honestly confused

Ok.
at least you should add
SCRIPT_UPDATE="no"
TTY2OLED_UPDATE="no"
to your user ini file to disable the tty2oled fw updater.

Or simply don‘t run the tty2oled updater script, there is no need for.
This should added to the matrix setup howto.

Damn! I already flashed the ESP32 by mistake with the first TTGO/DTI option, is there a problem with this?

Just flash your system with the correct firmware.
You know how to use the Arduino IDE?

Frankly this is the first time I've used it ahaha, added to that my English sucks, but I'm already adding the ESP32 board to Aruino IDE. I hope I don't get lost in the next steps.

This is hows going

Use google for HowTo your Arduino Setup and the tty2oled Wiki as well.

Sorry! that's my bad. i should have been more specific about those instructions. i will try to clarify them:

the portion that goes on the MiSTer is venice's project. you use the tty2oled script/install to setup tty2oled so your MiSTer will send what core is being used via usb/serial to your microcontroller. but you don't use the tty2oled firmware. you use the tty2rgbmatrix.ino file on my github which reads the core and shows the correct image.

very impressive!

Could you please share how to connect the SD Reader to the ESP Board.

//Edit
In think I got it.
Do you use the Accelerometer Port of the Trinity?

I'm out of town at the moment but I think my code has comments or defines named after the pins. I am using the accelerometer pins on the Trinity.

on a trinity board there's a break out for pins 2, 34*, 33, 32, SDA, SCL, GND and 3v3. that's where my intention was to put an SDcard reader i picked up from adafruit -> https://www.adafruit.com/product/254

I pushed an update to my project, I now have all the features I wanted for myself implemented.
Changes include:
Arduino: Added OTA updates
Arduino: Styled HTML
Linux: Service now checks returned HTTP code
Linux: Request MENU.gif when Core.gif is not found on matrix SD
Docs: Photo of wiring

arkanoid gif is done. will upload to github shortly. also think i've got the SDcard loader code figured out so that should appear soon as well. will be a separate sketch so folks can choose. tho eventually i want to fully eclipse the original version with something that pulls right from the MiSTer but im not there yet.

been a really busy last few weeks. these are taking me too long to do.

Thanks for this project!
I'm building this for my bartop, but the problem that I'm having is that for some reason the gifs are not displaying. All I get is the string "CMDCOR,name of the core,-1" in the leds for a moment when I start a core and then I get the text MiSTer FPGA.
I've uploaded the gifs to the ESP32 without problems inside a 'gifs' folder.
I've still not received the trinity board so I'm using a ESP32_DevKitc_V4 I had laying around. I've used the wiring from the HUB75 RGB LED matrix library.
