FastLED庫

這個庫應該是大佬基於Adafruit NeoPixel的改進庫。

紅綠藍測試

基於Blink Demo修改而來

#include <FastLED.h>       //標頭檔案

// How many leds in your strip?
#define NUM_LEDS 9        //燈珠數目

// For led chips like Neopixels, which have a data line, ground, and power, you just
// need to define DATA_PIN.  For led chipsets that are SPI based (four wires - data, clock,
 

// ground, and power), like the LPD8806 define both DATA_PIN and CLOCK_PIN
#define DATA_PIN 0             //Neopixels 燈珠所在訊號線
//#define CLOCK_PIN 13        

// Define the array of leds
CRGB leds[NUM_LEDS];          //LED引數陣列

void setup() 
{ 
      // Uncomment/edit one of the following lines for your leds arrangement.
 

      // FastLED.addLeds<TM1803, DATA_PIN, RGB>(leds, NUM_LEDS);
