Hello,
So i want to control the 8x8ws2812b led matrix (one pin version): 8x8 RGB 64 LED Matrix 5V WS2812b - OTRONIC
This matrix only has V+, V- & IN so all the 64 leds can be programmed with just one pin.
Now i can get it to work WITH a library without a problem, i just want to try and program it WITHOUT using a library. I have searched the internet and asked AI but i just can't find how exactly do i need to send data to the input pin to get the leds to work.
Please try and keep it as basic as possible since i'm still a beginner, thnx.
In short, all matrix leds are connected in series. Each led contains a microchip that can receive commands from the previous. When controlling the matrix, you transmit commands to the first led via the IN wire, chip checks whether this command applies to it, and passes all the rest further along the chain.
You can read more on the Internet, for example here https://www.arrow.com/en/research-and-events/articles/protocol-for-the-ws2812b-programmable-led
since i'm beginner i can't just read a library and understand wtf it actually means lol
But the link you provided explains it perfectly.
Thank you so much, i'll try to make it work
Using the ws2812 LEDs without any library is too complex for a beginner. It is too complex for everyone except experts.
The code you have tried may be using 2 libraries: the Adafruit NeoPixel library and the Adafruit NeoMatrix library. You won't be able to get the matrix to work without the NeoPixel library. But you might be able to get the matrix to work without the NeoMatrix library, so maybe try that.
