Hey @hellbent, What are your thought on using 3 panels instead of 2? I'm building one of these for my arcade cabinet and 3 would fit better along the top. Would the gif files go across all 3 panels?

[hellbent]

if you added a third panel you'd have to do a few things:

1) you'd need to adjust the panels_in_X_chain to 3
2) you may have to play with the showGIF function so that the 128x32 images would be centered... not sure.

if i had a third panel i'd test for you but i've only got the 2 at this time. i was about to pull the trigger on some new smaller panels i saw on aliexpress to try those...

[Sartis]

@hellbent thanks for the info. I got 6 when I bought mine because I’m also building one for my mister setup. So it sounds like it may be doable. What are you planning with the smaller panels? Can you provide a link?

[hellbent]

by smaller i mean smaller pitch, still 64x32 just with elements closer together.

these are P2 panels as opposed to the P2.5 i'm using now.

[hellbent]

just pushed an upload to github that includes several other animated and static images i've pulled from eLLuigi, pixelcade, and from web2rgbmatrix's collections. i haven't had a lot of time the last week or so but im going thru finding images i like. if you have any suggestions let me know.

code also handles static gif files as well, can't remember if i said anything about that recently or not.

hope to make a detailed setup video soon.

Maybe the two Matrix Projects can share their Media Library. Just an Idea.

Maybe the two Matrix Projects can share their Media Library. Just an Idea.

I think this would be a great idea. @hellbent if this interests you please PM me and we can work out the details.

super hang-on gif created... this one was too powerful at 16ms per frame so i've had to slow it down to 30ms but it still looks good and fast to me. its also over a minute long! i need to dial it back in the future

shangon_big.gif

so this image might not display in your browser and im not sure why... it shows on twitter okay but firefox and chrome don't seem to like to show it for me so not sure if its just me or what... regardless the one here is the big blown up version for web viewing and you should grab the one from the github anyway.

Great Stuff

Question, which Program(s) do you use to build these Gifs.

[hellbent]

i am pulling all ready ripped sprites from various online sites like spriter's resource if they exist but for the complex animations like the one in super hang-on i'm running the game in MAME using MAMEUI and recording the output to AVI. then, using ffmpeg, i convert each frame to PNG which is then imported in series into Aseprite which is a great pixel drawing and animation application with support for all sorts of fun plugins and scripts using lua. get the animation how i want it and then export to GIF, then i optimize using ezgif online.

for example the color bands scrolling up and down in the super hang-on logo was all done by hand frame by frame. same with the transitions from the sega logo to the game logo and from those to the attract mode animations. the scrolling from the START flag down to the racers on the first attract mode animation was done by scrolling the animation using a script in aseprite which is much easier said than done (its temperamental and doesn't always give you the result you are looking for).

and then i had to do it all over again because i forgot the paint out the INSERT COIN flashing text on that attract animation.

[hellbent]

i swear i'm not dead... just been incredibly busy. haven't even had time to boot up my MiSTer for a few weeks at least.

[hellbent]

work in progress. actual in game title screen for arcade is a travesty but the marquee art is nice. this is adapted from the atari version i believe and then basically recolored. once im happy i'll add it to the arcade attract mode captures i've taken to make the final gif.

[McFunkerson]

I love this project! I have a full sized arcade I'm going to be putting a MiSTer into and I'm thinking about using tty2rgbmatrix... only going bigger.

Looking at the project it looks like I can change the panel size and number of panels at the top of the file. At 640mmx160mm it looks like I can go p2.5 (256x64), p2 (320x80) or p1.86 (344x86).

If I were to change the panel settings... and provide artwork at the correct resolution is this something that should "just work"? I am a software developer, but my experience with Aurdino is fairly small at this point so I'm not very familiar with the libraries at this point.

[hellbent]

the panel display library should be able to handle more screens in various orientations and layouts tho i only have the two ive used in my project so i personally haven't done this. there are several examples tho on mr faptastic's git hub for the esp32 dma library for multiple panels.

the gif code by larry bank is limited to a width of 320 pixels. tho you may be able to tweak it.

the code i've used is setup only for 128x32 so it would need tweaking to handle other resolutions. i've considered going up to 192x64 by adding 4 more of the same panel i'm using but haven't got the cycles at this time. as it is im way behind on making the animated gifs!

[McFunkerson]

OK, I just ordered 2 160x80 panels, a esp32-trinity, and the sd card reader pcb from adafruit. Since most of that is shipping from china it might be a while before I can tinker with it though .

If I were to clean up the core image mapping section and make the script easier to configure for different panel sizes would you be open to pull requests?

Edit:
Actually, I probably should have looked at the docs for the
ESP32-HUB75-MatrixPanel-DMA first. It states:

Resolutions beyond 128x64 are more likely to result in crashes due to memory constraints etc. You are on your own after this point - PLEASE do not raise issues about this, the library can't magically defeat the SRAM memory constraints of the ESP32.

And the panels I chose aren't compatible with the library either. Luckily I can cancel those since they haven't shipped.

Edit2:
Ok, higher resolution displays should be possible but at a reduced color depth. I'm having problems right now figuring out what panels to buy. Not all of them on ali express list their driver chip.

[hellbent]

yeah tahts the trouble with ali express. you never know what driver you are going to get.

Hi,

Here is the brand new ULTIMATE GIFS DLC with 8000 gifs !!!!

https://www.neo-arcadia.com/forum/viewtopic.php?t=67065

[eLLuiGi]

Next goal is 10k gifs !!!

[hellbent]

finally finished the bosconian gif. it's up on the github now.

bosco_big.gif

[McFunkerson]

I was able to get everything up and running at 256x64 (4 64x64 panels). I did have to set the color depth to 6 bit due to memory limitations, but I think it looks pretty decent.

Now I need to start making 256x64 artwork.

@hellbent, I don't want to step on any toes but I made a fork of your repo and made some changes. First, I reorganized the code to be a bit easier for me to follow and easier to configure for different set ups.

Functional Changes I made:
The app now looks for animated art based on core name, then static art, then fallsback to a default image (as opposed to needing hard coded paths for each core).
GIFS are loaded from the SD Card once and played/displayed (animated/static) until there is a core change (instead of being read from the SD Card every loop).
GIFS are now centered if they are smaller than the display.

My fork is here: https://github.com/KrisConrad/tty2rgbmatrix

If you want me to make a PR I can.

[hellbent]

sounds like you went above and beyond my new version i've been testing for a few weeks and haven't released yet.

uses marquee file structure as agreed upon by kconger, venice and myself in a separate repo.
look for animated, if no look for static, if no just text
fewer static image loads to cut down on sd card wear and tear.

but i will defintely check out your code! panels look great btw. great job!

had some time during lunch and got the sdcard pins how i wanted them originally. standard header pins won't clear the power screw terminals so i used some longer ones.

Hi

fantastic work , can you put a pinout scheme for others micro sd adapters.. not adafruit. i have these for example.

adapter.jpg

the name of the pins of the adapter does not match that of the esp32trinity pins

its confused

thx

[hellbent]

i picked the adafruit sdcard adapter because it somewhat lined up with the default pinout of the trinity board but if you are gonna use a board with a different pinout here are some general guidelines...

1) sdcards are 3v3 and so if you have 3v3 on your board use it. the board in the image you sent has an AMS1117-3.3 voltage regulator that looks like it can step voltage down to 3v3. but im not 100% sure of that. im also not sure what it does if you supply only 3v3 to it and not a higher voltage that it would be expecting.
2) SPI uses all sorts of different names for essentially the same thing. MISO and MOSI are Master IN Slave OUT and Master OUT Slave In respectively. those terms have been super ceded by SDA and SDO or DATA_IN and DATA_OUT etc. the are the SPI equivalent of TX and RX for serial.
3) CS is chip select, used when multple devices are on the same SPI bus
4) SCK is the clock pin.

so if you want to use your board with the sketch as its configured on the github you would connect the following by using some male to female dupont jumper wires. also if you fry it don't blame me! but this is what i would try.

CS goes to pin 33 on the trinity
SCK goes to SCL on the trinity
MOSI goes to pin 32 on the trinity
MISO goes to SDA on the trinity
VCC goes to 3v3 on the trinity (but based on your sdcard adpter, you may have to supply 5v but i'm not sure, i'd start with 3v3 tho).
GND goes to GND on the trinity

with all that said, you CAN change the sketch to more closely match your pins if you want. but i'd start with this and see how that goes first. also make sure your sd card is a good one and formatted appropriately. ive had trouble with some low quaility or older cards and have had to re-format them to get the sketch to boot without a traceback error.

Thanks for your hard work on this project.

I can't get the brightness to change in the new SD version. I managed to change it before with the value in dma_display->setBrightness8(128); //0-255
I tried different values but it doesnt change and it always draws the same amount of current too.

Another note: I can't get your newest version to complile for the ESP32 Dev Module. It gives me an error:

"\tty2rgbmatrix-main\arduino\tty2rgbmatrix\tty2rgbmatrixx\bootloader.bin" kann syntaktisch an dieser Stelle nicht verarbeitet werden.

exit status 1

Compilation error: exit status 1

The older version i downloaded some time ago works though (It has the issue with the brightness though)

[hellbent]

well that's unfortunate... let me just bite the bullet and push the new version i've been testing.

what arduino IDE version are you using as well as what version of the AnimatedGif and ESP_HUB75_LED_MATRIX_PANEL_DMA libraries are you using?

here's what i am using and i can compile no issue in IDE 1.8.19 (i don't care for 2 thus far)

Code: Select all

just pushed the no if/else table version and double checked it compiles and it works great for me. and the brightness works as well. with no diffusion acrylic on it i keep it at 16 but if i change it to 64 from that its definitely brighter.

[Miru]

After reinstalling the Arduino IDE (which didn't solve the problem) i figured out the issue:
Take the tty2rgbmatrix.ino out of the downloaded folder (dowload ZIP from github), put it somewhere and let arduino make a new foldêr. And voila: It compiles.

And the brightness changes now too.
Strange issue

[Sliff2000]

So I have a ESP32-Trinity board that I successfully uploaded and everything looks great. I wanted to screw around and see if I can add another panel which I changed on line 111. Compiles no issue -- but when it goes to upload I get:

I also tried the OTA and I get Method Not Allowed

I had the trinity unpluged from the led boards and only plugged into the usb to my pc. I

Obviously I'm doing something wrong -- any guidance would be appreciated. Thanks ((Fortunately it is still working!))

[hellbent]

tty2rgbmatrix doesn't use OTA for updates, web2rgbmatrix does tho so i think you may be confused on where to post this issue. you might using kconger's version from this thread viewtopic.php?t=5330

[Sliff2000]

Sorry man.... need to stop drinking wine before working on this stuff.
