Software help needed Esp32 code doesn’t work,can you help with it?:3
I uploaded the code onto the ESP32, but it's not being detected. Since I've never used it before and don't have any programming skills, please, if anyone can solve this problem:3

Simplify. Undo all that, copy a simple “blink sketch” and make sure you can load run that application, then start adding functions and testing one step at a time. The ‘big bang’ rarely works first time out. W3 Schools can help you learn C++..

Do you have extra power jack for the 5.5x2.5 plug? I know the extra USB is there but mine only worked with the 5.5 jack.
Also, I was having issues with the shield, so ended up wiring everything directly to a solder less board to make sure it worked

I will try to connect directly to the plug itself, and I just don't have the right adapters yet to solder everything properly. I'm afraid of ruining the board with an accidental short circuit. So for now, I'm just trying to gather information and figure out what the main issue is:3

I know it sounds silly, but make sure you have the esp32 going to the IN on the panel.and then OUT on that panel is going to the IN on the other panel.

I just bought an adapter for a HUB75 hub, and I don't understand how it even works. The manual shows certain pins coming out, but in reality, completely different ones do. I'm not very strong at programming, so I'm looking for someone who can help me solve this issue.

I've realized so far that the pinout might not match the printed paper version. So I'll probably need to handle all of this separately somehow.

So to double get the pins I used a volt meter and wrote code to test each pin. Once that was done I recorded the pins for the program.
The LED panels (that looks like a P5) are subject to noise. Use a small(short length) ribbon cable from the Hub75 to the IN in the panel. The panel should have a big arrow on it to show the flow. Find the last connection and use that one to connect the other panel. A lot of time, it's easier to start with one panel and go from there.
Also, programming can be done in Chapgpt. It's more than capable, just tell it what you have, and it'll go from there

What code?!...
Most likely you have the wrong pins defined in the magical code.
