...mapped to a 240 LED Strip with WS2812 on a cylindrical matrix...



Because many people asked here a quick solution how to map the whole matrix to a strip:

  * An example for the Arduino particle system library
  * Creates a spinning galaxy effect
  * Note: this example uses the colorduino library becuse that is what I had,
  * but any device that supports setting a pixel to an RGB value can be used

//#include <Colorduino.h>
#include <FastSPI_LED2.h>
#include "ParticleSys.h"
#include "Particle_Bounce.h"
#include "Emitter_Spin.h"
#include "PartMatrix.h"

#define NUM_LEDS 240


const byte numParticles = 600;

Particle_Bounce particles[numParticles];
Emitter_Spin emitter(112, 112, 5, 7);
ParticleSys pSys(numParticles, particles, &emitter);
PartMatrix pMatrix;

* Render the particles into a low-resolution matrix
void drawMatrix(){
    pMatrix.render(particles, numParticles);
    //update the actual LED matrix
   for (byte y=0;y<8;y++) {
        for(byte x=0;x<8;x++) {
            //Colorduino.SetPixel(x, y, pMatrix.matrix[x][y].r, pMatrix.matrix[x][y].g, pMatrix.matrix[x][y].b);
    leds[40+(x*2)+y*20].r = pMatrix.matrix[x][y].r;
    leds[41+(x*2)+y*20].r = pMatrix.matrix[x][y].r;
    leds[40+(x*2)+y*20].g = pMatrix.matrix[x][y].g;
    leds[41+(x*2)+y*20].g = pMatrix.matrix[x][y].g;
    leds[40+(x*2)+y*20].b = pMatrix.matrix[x][y].b;
    leds[41+(x*2)+y*20].b = pMatrix.matrix[x][y].b;

void setup()
  //Colorduino.Init(); // initialize the board
  FastLED.addLeds<WS2812, 6, GRB>(leds, NUM_LEDS);
  // compensate for relative intensity differences in R/G/B brightness
  // array of 6-bit base values for RGB (0~63)
  // whiteBalVal[0]=red
  // whiteBalVal[1]=green
  // whiteBalVal[2]=blue
  byte whiteBalVal[3] = {36,63,7}; // for LEDSEE 6x6cm round matrix

  //Colorduino.FlipPage(); // swap screen buffers to show it
  emitter.oscilate = true;

void loop()
