Really nice conclusion of your stream. I did not find the time to try out mine at all but I surely will in the next days when my garden is finished to be planted.

[@BrianLough]

It's actually pretty straight forward to setup, the stream would have been a lot faster if we didn't run into that crashing issue! I have a few more plans for this display too, but I have lots of projects on the backlog so we'll see!

[@Hasitier]

Brian Lough now I am really interested in what you will do with it because I do not have a particular plan what i will display on mine.

[@followthetrawler]

I am going to use this as a display to monitor my firewalls blocked and permitted connections. Should be fun to try.

[@vianquies]

Do you have a diagram to connect the esp32 to the 64x32 control panel? I'm trying and it gives me error :(

[@Borszczuk]

I believe wiring shown @3:59 is incorrect. According to PxMatrix docs the green wire between PIn and POut should be from B1 (B0) to G2 (G1) and you got it drawn hooked to POut's E (4th pin in 2nd column), instead of 3rd pin.

[@golf-n-guns]

[@gregclare]

Nice summary Brian! I just received my display panel today. I ordered it during the stream where you were struggling to get yours going (inspired by the challenge. LOL). Now that you’ve done all the hard work, I’ll get mine hooked up to an ESP32 and start thinking of an application for a pretty cool display module. :-)

Do you have a screen shot of the wiring? Still stuck on that aspect.

[@DarrenHedlund]

Thank you!!! Awesome videos you have created.

[@HariWiguna]

Thanks for the tldr version of this. When you figure out how to shoot LEDs, you need to make a video because I always get frustrated with that too.

[@Jelmister]

The flickering is caused by the shutter rate of the camera. If you are using a camera where you can play with shutter speed you need to try to match it to the flicker of the LEDs. More advanced cameras like my gh4 have a feature called synchro scan where you can adjust the shutter angle to the degree instead of the normal click jump up and down.

[@movingpictures9308]

I'm trying to get my Matrix to work with an ESP8266 but it just doesn't work. I did everything as you described in the Video but my Matrix only Says Pixel Time in the corner and is fading all pixels from 0% blue to 100% blue over and over. Any ideas?

[@violentcrumble6720]

this is an old video but thank you regardless. Surprisingly it almost worked for me. when i run the example Pixel time however the bottom half of the text is cut off. I am not sure what my issue is. I have definitely checked and the E pin is actually ground so i removed that pin. I checked the others tho and they are no ground. I also think i found my pinout but it's impossible to know. I am using a nodemcu v3. I triple checked the pins being assigned to lat, a, b, c, d, and OE and they are all correct. but the example code does not seem to mention CLK anywhere and i have it plugged into D5 could that be causing my issue? Another thing i noticed is the G1 which is presume is Green1? is running to R2 on the output? is that correct? I figured G1 would go to G1 etc. Thank you if you decide to reply it would mean a lot!

No worries! I haven't tried it but seems like the library had an update recently to support chaining together, I'm not sure how fast it works but you can see an example on the readme of the library.

[@uygar84]

Thanks for the project Brian. My LED Matrix, which is same as yours, works great but when I use it for instance to get Bitcoin price online, it flickers when ESP8266HTTPClient library is using the GET function, for the entire duration (1-2 seconds). Any idea why this could be, and how I can make the transition from one value to the next smooth and flicker-free? Could it be a faulty ESP8266 or power supply? Everything works great otherwise. Cheers mate!

[@vinny142]

just in case anybody else reads this: the RGB panel doesn't have internal memory, the ESP8266 has to constantly provide the state for each of the LED's. if you make the controller do something that prevents it form updating the screen fast enough then you'll get flicker. Given the price of ESP8266 and even ESP32 today you could try using a second ESP just to control the matrix and do the heavy stuff on another.

[@movingpictures9308]

Hey Brian, I could need some advise for a Project. My plan is to get some ws2812b led strips and this panel and hook them up so that I can control them via WiFi. What boards do you recommend for that? I only have experience with Arduino, so It would be best if they work in a similar way. I thought I'd get 2 of the wemos D1 mini(one for the panel and one for the led strips) and then connect both to my home network to control them with my phone for example. What do you think?

[@BrianLough]

D1 mini would be perfect for that yeah, it's very similar to a regular Arduino other than WiFi stuff. I recommend getting a logic level shifter as sometimes there is issues controlling ws2812b leds with a 3.3v signal. Check out "mclighting", it is a sketch for an esp8266 that has a web interface for controlling ws2812bs

[@movingpictures9308]

Brian Lough oh, yeah I totally forgot that the D1 only outputs 3.3v. From what I have seen in other videos I can connect the wemos to my home network and then just need to type in it's IP address in my web browser (which I can make an app for) to trigger stuff on the wemos, right? I just found an old computer power supply which says Output:5V/25A, gonna use that on for my project.

Hey Brian, thanks for the help, I actually got it working. However, I wanna do something similar to the Banana Dance but with 19 frames, since the memory can't handle that I wanted to do it via flash, is that possible? And how would I do that?

[@BrianLough]

I've never tried it, but for the frames, instead of keeping arrays of uint16 to store the colours of every pixel, you could store every colour that appears in the frames in one array , and then change the frames to be arrays of unit8 that are made up of index's to the colour array. This, in theory, should allow you to double the amount of frames you can have.

[@GreenOnionBrother]

@@BrianLough thanks, but I actually found a better way using "const uint16_t **********[] PROGMEM =" and then "drawFrame(const uint16_t *frame)" and "display.drawPixel(xx, yy, pgm_read_word(&frame[counter]));" Works well enough.

Another post is saying you need to look for ground pins on the "output side " connector of the matrix and connect them to the ground of your WemosD1Mini. Just tested it. I confirm it reduces the red green and blue noise significantly.

Vlaming?

[@tycstahX]

Als je de esp8266 voedt met de 5V bron van de Matrix dan heb je nul "noise". Best een diode gebruiken wel in dit geval om ongelukken te vermijden. Je wil de matrix niet per ongeluk "tijdelijk" doorheen je ESP8266 van stroom voorzien terwijl je die re-flashed. (of gewoon eerst je code goed krijgen met ruis en dan 1x flashen en met je zijdezachte poten afblijven. :D)

6 amps ? Wow!!! What a power hog. If that is a 12 volt power supply, that's 72 watts. That kind of kills this project for me.

It's a 5v power supply. I've since measured it and it uses 2.6amps when fully white. But I also don't really trust these Chinese power supplies

@@BrianLough Hi Brian Thanks for sharing , question : 2.6 amps of mains or SMPS ??

[@BrianLough]

@@TheJay6621 2.6 amps is after conversion to DC, so maybe 15w of power on the AC

You can never be too careful :) I think I was just worried about Amazon revealing my address somewhere
