delay(wait) in strandtest sketch

[bunger]

First off: just got my flat RGB LEDs strand today and they are A-W-E-S-O-M-E!!

With that said, I was looking through the strandtest sketch and there are calls to delay(wait) in each color sequence loop.

I looked around for the the definition of the wait variable, but couldn't find it in the sketch or libraries. I am new to Arduino programming, so maybe I am not aware that it is something right under my nose?

Howdy!

'wait' is a parameter being passed to each animation function. For example, you'll see it's received in the first line of this function here:

Code: Select all

void colorWipe(uint32_t c, uint8_t wait) {
  int i;

  for (i=0; i < strip.numPixels(); i++) {
      strip.setPixelColor(i, c);
      strip.show();
      delay(wait);
  }
}

The value of 'wait' is then specified by the code that's calling colorWipe, e.g. the '10' you see here:

Code: Select all

  colorWipe(strip.Color(127,0,0), 10);

Doh!!! I TOTALLY missed that. Been a loooooong week!

Thanks for setting me straight.
