clock freeze with neopixel

Using Arduino Programming Questions
#1

Hi,

I am thinking about a cool idea for my 7 segment display clock and I am not sure that it is possible.

So my “problem” which is more like a question, is, is it possible to run the neopixel (with a color cycle) and my clock at the same time without the clock freezing? (I have a blinking “:” in the middle of the 7 segemnt display so thats why I know when it is freezing.)

#2

is it possible to run the neopixel (with a color cycle) and my clock at the same time without the clock freezing?

Sure. Just make sure the temperature in the vicinity stays well above the temperature at which the clock freezes.

Having the colon on the seven segment display stop blinking does not mean that the clock has frozen.

It is completely useless to post in the Programming section and not post your code.

#3

I made it to blink when the second can be devided by 2 so it is blinking every 2 seconds. If it is not blinking, it is frozen.
As I said it is more like a question, but sure, I can paste a piece of my code.

void setup(void)
{
  #if defined(__AVR_ATtiny85__) && (F_CPU == 16000000)
    clock_prescale_set(clock_div_1);
  #endif
  
  strip.begin();           // INITIALIZE NeoPixel strip object (REQUIRED)
  strip.show();            // Turn OFF all pixels ASAP
  strip.setBrightness(25);

kijelzo.begin(0x70);
  kijelzo.setBrightness(fenyero);
  Serial.begin(115200);

  idoKliens.begin();
  idoKliens.setTimeOffset(7200);
}

void loop()
{     
  oraDolgai();
  rainbow(10);
}

void oraDolgai(void)
{
  idoKliens.update();
  String masodperc = ((idoKliens.getFormattedTime().substring(6)));
  String perc = ((idoKliens.getFormattedTime().substring(3)));
  String ora = ((idoKliens.getFormattedTime().substring(0)));
  int masodpercc = masodperc.toInt();
  int oraa = ora.toInt();
  int percc = perc.toInt();

  unsigned int oraaa = oraa;
  unsigned int perccc = percc;
  unsigned int masodperccc = masodpercc;

  unsigned int ideiglenes = perccc;
  do
  {
    ideiglenes /= 10;
    oraaa *= 10;
  } while (ideiglenes > 0);

  if (perccc < 10)
  {
    unsigned int kisebb = oraaa * 10;
    unsigned int pontosido = kisebb + perccc;
    kijelzo.print(pontosido);
  }
  else
  {
    unsigned int pontosido2 = oraaa + perccc;
    kijelzo.print(pontosido2);
  }

  if (masodpercc % 2) {
    kijelzo.drawColon(false);
  }
  else
  {
    kijelzo.drawColon(true);
  }
  kijelzo.writeDisplay();
}

void rainbow(int wait)
{
  for(long firstPixelHue = 0; firstPixelHue < 5*65536; firstPixelHue += 256)
  {
      for(int i=0; i<strip.numPixels(); i++) 
      {
        int pixelHue = firstPixelHue + (i * 65536L / strip.numPixels());
        strip.setPixelColor(i, strip.gamma32(strip.ColorHSV(pixelHue)));
      }
    strip.show();
    delay(wait);
  }
}

Please don’t mind my AWFUL clock code which totally doesn’t make any sens, but it is working lol
I also have a weather monitor in my program so I won’t paste the whole code because thats like 400+ lines.

#4 
    delay(wait);

You can not do two (or more) things "simultaneously" when you use this function. Especially not when you use it in a loop.
