WebThe lowest working number you can use is '1', but you won't get a continuous rainbow all the way through. There's an open PR to add a continous rainbow function. Until it's merged with the library you can borrow that code from here. Then usage will be: fill_rainbow_circular (leds, NUM_LEDS, 0, false); 5. WebMay 6, 2024 · I saw this example of fill_rainbow. Its from the FastLED library: When I look at the code, I see that it takes an existing array, then "moves" it along the LED strip. With this line fill_rainbow ( leds + 1, NUM_LEDS - 1, --starthue, 20), does the number 20 refer to the number of LEDs it will squish the array into?

WebMar 10, 2024 · All the functions (rainbow, juggle, etc) just need to work on your leds[] array that you gave to FastLED.addLeds() in your setup()-- I assume that your functions already fulfill that requirement. But: All functions must have the same argument list (in this case: they must be defined like void rainbow() { leds[x] = CHSV(a,b,c); } ), so you might ... WebHere's a simple blink program: #include "FastLED.h" #define NUM_LEDS 60 CRGB leds [NUM_LEDS]; void setup () { FastLED.addLeds (leds, NUM_LEDS); } void loop () { leds [0] = CRGB::White; FastLED.show (); delay (30); leds [0] = CRGB::Black; FastLED.show (); delay (30); } Supported LED chipsets

After the last pixel’s worth of data is issued, the stream must stop for at least 50 microseconds for the new colors to “latch.” For a strip of 100 pixels, that’s (100 * 30) + 50, or 3,050 microseconds. 1,000,000 / 3,050 = 328 updates per second, approximately.
