I am creating a project using Adafruit neopixels. I have tested the hardware using a simple program and that isnt the issue. Using the library is fine, but what I wanted to do is make a wrapper class which acts as an adapter since I want to think about my neopixels as a grid and set them using x,y c…

[image] bold_and_brash: but the LEDs are actually wired in a snake sort of pattern. That is called a serpentine raster. There are four ways to wire this up and the exact solution depends on which way it is wired. Basically on some lines the formula is like xfpd gave you but on other it is a d…

@bold_and_brash you seem to be re-inventing the wheel. [image] Adafruit NeoPixel Überguide NeoPixels are “intelligent” full-color RGB LEDs that can be controlled and chained from a single microcontroller pin. This guide presents an overview of NeoPixel products, along with tips for buil…

[image] bold_and_brash: snake sort of pattern Odd rows (ROW % 2) count LOW to HIGH, even rows cound HIGH to LOW (PIX_PER_ROW - COL). It is buried in here somewhere. The algorithm even counts rows backwards, top to bottom to a "snake" cofigured foe bottom to top. Math makes fun, funner! …

I will look into this guide and the modules mentioned. It seems like maybe I can use those. I still personally wouldve liked a wrapper class but I guess I can implement fades and animations as stand alone functions. However. To all the other replies, I can not stress this enough: The problem is not…

I suppose yes I could use the NeoMatrix module, or indeed move my own indexing function into main and store a 2d array as a global variable and make all my functions in main and make it a really messy file. My question is more why when I refactor it into its own wrapper function does it seem to no l…

[image] bold_and_brash: LEDController.push() the contents of ColourBuffer are not being reflected onto the physical LED strip Wrong color? Dim color? No color? Passing colors require sending the array (as a pointer).

Could you post the entire code, its not possible to compile without the header files.

The headers are fairly standard, but sure they are included below: colour.h #ifndef colour_h #define colour_h #include <stdint.h> // For uint8_t and uint32_t #include <Arduino.h> class Colour { public: uint8_t r; uint8_t g; uint8_t b; Colour(uint8_t red = 0, uint8_t green = 0, …

The LED strips do not light up at all. The colourBuffer stores the correct values but calling push() causes no LEDs to turn on. I do not need to pass a pointer because i am reading from the class attribute directly, and then calling the setPixelColor function which is aprt of the adafruit library

Its worth mentioning at this point that thanks to @PaulRB 's suggestion I have done more research and found that not only had this problem been solved before, its then been solved again by the FastLED library. This can literally do everything I wanted my class to do and more, and I will be using that…

It is about not having delays. Sending out the 24 bits * number of pixels with the right timing. Andreas Kuzechie does a good job of explaining the WS2812B...
