Adafruit_NeoPixel pixels(NUMPIXELS,PIN,NEO_GRB + NEO_KHZ800)这句是新建一个灯板对象,基本上咱们接触的都是V2版本的灯板,所以NEO_GRB + NEO_KHZ800基本是固定组合的,除非你用了带白光的灯珠,那就用NEO_RGBW + NEO_KHZ800。这个注释里说的很清除了,不多啰嗦了。 参数1 =新像素带中的像素数 参数2 = ...
Arduino library for controlling single-wire-based LED pixels and strip such as the Adafruit 60 LED/meter Digital LED strip, the Adafruit FLORA RGB Smart Pixel, the Adafruit Breadboard-friendly RGB Smart Pixel, the Adafruit NeoPixel Stick, and the Adafruit NeoPixel Shield. 库文件下载地址: Adafruit...
( a separate tutorial explains its use.)Adafruit_NeoMatrix库中也包含了一些示例草图。 我们在这里只关注构造函数—是如何声明 由NeoPixels构成的 二维显示。为这个家伙供电则是另一回事,前面一页已经介绍过了。 该库处理单一矩阵-所有NeoPixels在一个统一的网格-平铺矩阵-多个网格合并成一个更大的显示器: 让我们...
“NeoPixel” is Adafruit’s brand for individually-addressable RGB color pixels and strips based on the WS2812, WS2811 and SK6812 LED/drivers, using a single-wire control protocol. Other LED products we carry — DotStars, WS2801 pixels, LPD8806 and “analog” strips — use different ...
并非所有可寻址的LED都是NeoPixels。“ NeoPixel”是Adafruit的品牌,基于 WS2812 , WS2811 和 SK6812 LED/驱动器,可分别寻址RGB彩色像素和条,使用单线控制协议。我们提供的其他LED产品-DotStars,WS2801像素,LPD8806和“模拟”灯带-使用不同的方法(并有自己的教程)。 在论坛上寻求技术支持时,如果提到正确的LED类型,...

Adafruit_NeoPixel pixels(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800); 实例化完成后需要通过Adafruit_NeoPixel类中的begin()方法完成类的初始化操作。例如:pixels.begin();。 下面简单介绍一下Adafruit_NeoPixel类中常用的一些方法。 void Adafruit_NeoPixel::clear(void)--用0填充整个像素条,即关闭所有WS2812灯珠。

Controlling NeoPixels “from scratch” is quite a challenge, so we provide a library letting you focus on the fun and interesting bits. The library is free; you don’t have to pay for anything. Adafruit invests time and resources providing this open source code, please support Adafruit and ...
