Hi, I have a 16x16 LED panel for a project in my club. I’m trying to have the panel display a specific kind of image but I have no idea how to go about that. I’ve tested and the examples but don’t know how to light up only specific leds in code

For matrix sprites try looking at http://jorgen-vikinggod.github.io/LEDMatrix/

I followed the LED Matrix tutorial. But I don’t know how to use the void drawline function into my code.

Try this if you’re using neopixels http://marc.merlins.org/perso/arduino/post_2017-04-24_Adafruit-GFX-on-NeoMatrix-and-RGB-Matrix-Panel-Demo.html

@vince_rosane slightly off topic of your DrawLine dilemma, but in you attached imgur photo showing your code you have the chipset defined as ws2811 but are initializing the leds as ws2812 without the CLOCK_PIN defined. If you have examples working please disregard.

Hi, I’ve come a very long way and have done a lot of things. I’ve been able to display images like the Norwegian Flag, Japanese Flag and to even make my own functions that draws shapes based on coordinates. But now there’s a problem. For some reason, the drawPixel() function doesn’t work. Can you please help me
