用Adafruit_NeoPixel-1.3.4的全彩燈條 Arduino源程序

ID:69091 · 發表于 2020-3-10 14:13

經實物實驗60顆全部點亮。多種顯示方式。

Arduino源程序如下:

/*
strip.setPixelColor(uint16_t n, uint8_t r, uint8_t g, uint8_t b);
第一個參數n是彩帶中LED的編號,最接近單片機引腳的編號為0;接下來的三個參數描述像素顏色,分別表示紅色,綠色和藍色的亮度級別,0為最暗,255是最大亮度；
strip.setPixelColor(uint16_t n, uint32_t c);
n是彩帶中LED的編號,顏色color是一種32位類型,將紅色,綠色和藍色值合并為一個數字,有時這樣做能提高程序的效率.通過下面的方法,可以將紅色,綠色和藍色值轉換為32位類型。
uint32_t magenta = strip.Color(red, green, blue);
strip.setBrightness(uint8_t);
一般只在setup()中調用，以保證在整個程序執行過程中LED顏色亮度的一致性,其實在程序中通過合適的邏輯控制各像素的亮度值可能動畫效果更好.
strip.show();
該方法更新彩帶上的全部LED。一個好的習慣是先利用setPixelColor()設置好整個彩帶的顏色，然后再調用show()方法，以防止出現動畫跳躍而不平滑。
