Code optimising ws2812 led matrix & Arduino

JKElectronics · December 23, 2022, 10:55am

Hello,
I'm pretty new to coding, and I would like to make a ws2812 led matrix 8x8 light up.
the purpose is that all the 64 leds are lit up at the same time & change color after delay..
i have a code that works perfectly & does the job.. but it's long code with lots of repetition in it..
could someone pls help me to minimize the code with I think array?? so that code is a lot smaller but still does the same job?
I don't know how to begin on it..

thanks in advance

#include <Adafruit_NeoPixel.h>
#define neoPin 7
#define NumPixels 64
Adafruit_NeoPixel pixels(NumPixels, neoPin, NEO_GRB + NEO_KHZ800); // NEO_GRB

  pixels.begin();

Take a look at the for loop

JKElectronics · December 23, 2022, 11:04am

for (int i=0; i<64; i++) pixels.setPixelColor((i),(80),(0),(90));
pixels.show()
delay(1000)

Like this then?

works like a charm!
thanks for the help @anon56112670 !

If all the pixels needs the same color.

 fill_solid(pixels, NUM_LEDS, CRGB(red, green, blue));
 FastLED.show();
