define语句在编程中类似于变量声明，但专门用于定义那些在程序运行过程中不会发生变化的信息，例如引脚编号或LED灯数量。这类信息一经设定，即成为常量，不会因程序执行而改变。相较于常规的变量声明，define语句在内存占用方面更为高效。strip.show()函数用于更新像素灯带的显示状态，使得像素颜色能够发生变化。这个函数...

Arduino使用neopixel卡住控制ledstrip 、、、 我试着用我的pi 3控制一个rgb ws2812b led条带,效果很好。现在我想用我的ArduinoNano来做这件事。控件本身是有效的。如果我将一些代码放入循环函数中,一切都会正常工作。代码如下:#define shortStrip 2#define led_count_short23 Adafruit_NeoPixelstrip_short 浏览...
