Title: Problem- LED Matrix 64x32 + Nodemcu 12e, please help.
Post by: consig1iere on Aug 21, 2019, 09:32 am
Just received a RGB LED Matrix 64x32 panel, I bought it from Aliexpress from SRYLED seller. I don't know if the panel is defective or I am doing something incorrectly... the panel won't turn on certain parts of the screen. I have posted a photo for a better explanation. I have also posted the pinout of this particular board. Is there any way I can fix this? Btw I am using Brain Lough's tutorial.

Whoever he is!  How would we know?  :smiley-eek:

And your actual code?

(Please read the forum instructions (http://arduino.cc/forum/index.php/topic,148850.0.html) regarding how to post code.)

This is the tutorial I followed: https://www.instructables.com/id/RGB-LED-Matrix-With-an-ESP8266/

He has couple example files: https://github.com/witnessmenow/LED-Matrix-Display-Examples

Even though I mentioned Nodemcu 12e, I also tried it with a Wemos D1 Mini just like in the tutorial.

have you read the tutorial carefully? It looks like he explains this problem:

if you want help from others: helpers need YOUR actual code, CLEAR pictures of YOUR setup. Links (clickable!!!) to YOUR devices you bought.

Best help can be provided if you order a display for at least one of your helpers.
