I've tried doing a lookup of the word error and nothing pops up and the program doesn't work when I run this. The program does work when I use an esp32 but that board wont work with a different program I need to use that the esp8266 should work with. Any help finding the issue would be greatly apricated.

"register" is a hint to the compiler that it should try to leave the variable in a machine register, which should allow faster access than putting it in RAM.

The warning message looks pretty clear to me.

hound312 · May 25, 2023, 5:57pm

I'm pretty new to this language and c++ in general, how would I do that? this is all that my code is and the warnings are coming from the FastLED library

#include <FastLED.h>
#define WIDTH 36
#define HEIGHT 31
#define LED_PIN 4

const int NUM_LEDS = WIDTH * HEIGHT;
CRGB leds[NUM_LEDS];

void setup() {
  FastLED.addLeds<WS2812B, LED_PIN, GRB>(leds, NUM_LEDS);
}

void loop() {
  for (int i = 0; i < NUM_LEDS; i++){
    leds[i].r = 100;
    FastLED.show();
    leds[i].r = 0;
    delay(10);
  }
}

I've used FastLED on plenty of esp8266 projects without getting those errors.

What version of the FastLED library and IDE are you using?

hound312 · May 25, 2023, 6:12pm

I have FastLED 3.5.0 installed, IDE 2.1.0, and ESP8266 Board Manager 3.1.2 installed

anon56112670 · May 25, 2023, 6:16pm

How would you do what?
The warning message is just that - "register" is a hint, and the compiler has ignored it.

PaulRB · May 25, 2023, 6:28pm

Ah, yes, they are not errors, only warnings. Maybe I never saw them because I didn't have warnings level of detail enabled.

Have you tried one of the standard example sketches that are installed with the FastLED library?

What model of ESP8266 board are you using and is there a label next to the pin you are using, eg. "D4" ?

hound312 · May 25, 2023, 6:38pm

You were right it was D4 instead of just 4! ty!
