144 neopixels

duitsman

Hi there,

 

I have a question for a product I am making for school. I have 144 neopixels joint together and want to make a photoshop animations. This PS animation has to work on the neopixel. For setting the color of each neopixel i use one line of code. setPixelcolor ( 0,233,20,84) like this but this is a lot of work when i have to set each pixel to one color for every picture i have. Does anyone know her how to set different pixels to one color the fast way. So lets say that i want 32 different pixel the color green. For example pixel 0, 2,5,8,19,34,50, 51,55 etc.

 

I know i can do this line by line but thats a lot of work with 144 pixel animations. 

 

Can i do this with a variable ? and if so can anyone help me with the program?

 

Greetings

  • You could perhaps make an array with all the values of the pixels you want colored a certain way, and using a loop go through the array and color each pixel accordingly. I'll give an example below.

    int greenPixels[] = {0,2,5,8,19,34,50,51,55};

for(i = 0; i < sizeof(greenPixels); i++) {
    pixel = greenPixels[i];
    setPixelcolor(pixel,233,20,84);
}
