Thank you very much for this tutorial - I'm writing an RGB matrix library for my high school graduation project and this was a crucial part in understanding the works.

Hands down best explanation on RGB LED matrices, I'm writing an rgb matrix library for my uni project and this'll be of great help.

May I know for which controller you are writing?

Thank you so much for this video. It helped me to spot what I was doing wrong with my ESP32 D1 Mini Breakout shield. I now have my panel working !

Thank you for your efforts, great video.

Love your work

Thank you , ithink this is the best video ever for explaining RGB modules 😊😊👏👏👏👏💪

Very good video and super explanation and visuals. This means all leds are strobing all the time even if the same picture is displayed? So the brightness is not even near the full brightness of the leds or are the leds overdrived because they only light up for short periods of times with relatively big pauses? This is a pretty interesting thing I think.

Thank you. Yes, you are correct. There is a short pause betweeen the time they light up, so they are basically strobing all the time.

I love this. It's very similar to the way an old school CRT would scan, these are perfect for making retro game screens with. The black spacees in between the pixels. Almost simulates CRT perfectly. It would be my dream to see some sort of driver that could arrange an analog signal into an LED matrix cleanly and without lag, but what we have now will work

That's true. This might work as some kind of a CRT replacement. 🙂

Woould you be able to use a PSOC 5LP to program this RGB LED matrix? If so do you have any examples?

Can I use? old flatscreen as LED Matrix Display

Hi there. Thanks for explaining this. I have a 64x64 panel that I want to use in an upcoming video. So this should help me figure that out. This is the only video I've seen that doesn't require some sort of shield. Question - will this work with an ESP32 as well?

According to the github page of PxMatrix it should also work on EPS32. Good luck with the video.

Good video👍🏼👍🏼👍🏼👍🏼

How about drivers that use not OE, but GCLK. (For example, MBI5252) How to manage them?

Great video how you created the atari logo do you have any program for that?

Thanks. I guess that an utility to do that must exist, but I was just counting pixels.

Great video. I have a p3 64x64 panel that only has letters abce there is a gnd pin where the d normally is. I havent been able to find a way to drive it. I have 7 of them....

Thanks. Intereting... I haven't seen configuration like this. Maybe you could try to trace where that grid pin connects to on the board and continue from there.

Very good video, but is not clear how the colors (NOT pure colors) are generated in the shift registers. Could you explain this please? It will be very useful. Regards.

I haven't really looked into it, but I think it must be using some kind of PWM scheme to blend the RGB colours.

What do you call what you do? Where do you study this? Understanding the nomenclature

It's electronics. And this area is called Sequential logic circuits.

why are you connecting from hub75 input to output ? isnt output to daisy chain to another display ????

@ezContents

In this way all the shift registers that are responsible for all the colours can be programmed by just one output of the ESP microcontroller.

Hello, I'm trying with 32x32 matrix. Is the pin connection going to be the same?

PxMatrix library does support 32x32 matrices. If it has HUB75 connectors then it should work.
