The raspi-config screen. Most OS-level options can be set here, including activating and deactivating services. Newer versions of Raspbian automatically expand your file system the first time you start the Pi. Unless you are using an older version of Raspbian, you should be able to skip this...
void Adafruit_NeoPixel::fill(uint32_t c, uint16_t first, uint16_t count)--使用一种颜色填充新像素条的全部或部分。c为32位的颜色值。first为要填充的第一个像素的第一个索引,从0开始,如果未指定,则默认从0索引开始。count为要填充的像素数,为正值。当是0或未指定将填充到条形图的末尾。 v
该24位WS2812环形灯板包含24个可单独寻址的RGB LED,这些LED以紧密间隔排列,所有这些均可通过微控制器的单个数字输出进行控制。该环的外径为2.6英寸(66毫米),可以将多个环链接在一起,使其非常适合为小型机器人或可穿戴电子项目增加光泽。 功能和规格 24个可单独寻址的RGB LED(基于SK6812-或WS2812B的NeoPixels) ...
close look at the output window in the IDE for errors (in red). Common errors here could be missing libraries (go back to the installing dependencies section above) or the "Unsupported hardware" error, meaning you have not defined the target device (go back to the configuring hardware ...
