Vielleicht habt ihr auf vergangenen Chaos Communication Congressen, MRMCDs oder Easterheggs meine Raspberry Pi Pico basierte Arcade-Konsole gesehen, vielleicht auch damit gespielt – jetzt könnt ihr auch via #PyGame am Computer und sogar via #Pygbag im Browser (sogar mobil) damit spielen: https://simonwaldherr.github.io/DIY-Arcade-Machine/
Natürlich könnt ihr sie aber auch gerne nachbauen, Details dazu im Repo.

My hub75 based display has started having rendering issues lately. After messing around for a while and getting nowhere I believe I've finally fixed it by reducing the power supply voltage to 4.7V instead of 5V. I guess some of these displays don't really like 3.3V logic and reducing the difference helps.

The new Steam Machine is a cube measuring 160mm on a side. In completely unrelated news, Adafruit is still selling 64x64 LED matrices that measure 160mm on a side.

@PaulaMaddox Wow, this brings back memories. I had an almost identical bug in my own #FPGA #Hub75 driver.
Your bottom-most (in the photo) column looks correct; is this the first one that gets clocked out of the driver?
When do you update the ABCD mux signals? I had a bug here; I realised that you have to hold them steady until you've clocked out the entire next row, then update them at the same time as you pulse the LATCH and /OE signals.
Dunno if that helps - it was a few years ago!

Haven't seen this discussed anywhere so
Some #hub75 panels use an ASIC instead of a simple shift register for driving the LEDs to prevent burn-in etc - which means the chip expects a certain regular timing on its pins, else it goes dark. So if your simple test code isn't frigging latching and you've been debugging for hours, check your panel ICs!

a case for 2x 64x64 HUB75 led matrices, where the shell can easily be printed out of something nice (colorfabb woodfill here)

made a compact passive board for interfacing with #hub75 led matrices with a pi https://github.com/Knifa/pi2hub75

Ich habe die letzten Wochen an einem neuen Projekt gebastelt, eine DIY Arcade Konsole. Das Projekt ist natürlich #OpenSource.
Aktuell gibt es 6 Spiele (Tetris, Snake, Simon, Pong, Breakout, Qix). -

Uh-oh. The Adafruit fairy paid me a visit. I'm now in the "two free dev boards and a coaster" customer tier.

Finally got everything working with the Teensy. 😎 #LEDs #Teensy, SmartMatrix #HUB75 adapter, @wizard #PixelBlaze Expander, etc. Works in the actual installation too :)

I've now read through quite a bit of code that flys around to drive the #HUB75 panels. Ultimately, I have to praise the @adafruit code (i.e. https://github.com/adafruit/Adafruit_Protomatter/blob/master/src/core.c) by @PaintYourDragon (found only on the birdsite). I love #code to be concise, educational and visually appealing ;-)

#Rust: I made the toolchain work on the #ESP32. Some versioning woes, but nothing serious. Also got the #LED panel to work with the #embedded_graphics and the #hub75 driver. However I think I want to make a DMA version. Manual banging pins seems silly.
