sorry for the repost but I’m really upset now. 
I’m not a hardcore coder but I learned a lot since I started to work whit FastLED and Processing but I can’t solve one problem…
The problem is when I want to control my leds my framerate start at 9fps and slowly go down to 1… any idea? here my noob code
import processing.serial.;
import controlP5.;
ControlP5 MyController;
int red = 0;
int green= 0;
int blue = 0;
int HEIGHT = 15;
int WIDTH = 20;
int NUM_LEDS = WIDTH * HEIGHT ;
int[] leds = new int[NUM_LEDS];
Serial port;
void setup(){
size(500,500);
port = new Serial(this,Serial.list()[0], 1000000);
MyController = new ControlP5(this);
MyController.addSlider(“red”,0,255,0,height/2,width/2,30,150);
MyController.addSlider(“green”,0,255,0,height/2+90,width/2,30,150);
MyController.addSlider(“blue”,0,255,0,height/2-90,width/2,30,150);
}
void draw() {
background(51);
println(frameRate);
port.write(1);
for (int i = 0; i <=leds.length ; i++){
port.write(red);
port.write(green);
port.write(blue);
}
}
