Looking at the ebay page, it suggests that it uses WS2812 driver to control the LED. 查看ebay页面，它表明它使用WS2812驱动器来控制LED。 Thankfully, that LED driver is pretty common, which means there is plenty of available (and open-soure) code for it. 值得庆幸的是，LED驱动器非常普遍，这意味着它有很多可用的（开放源代码）代码。
Documentation for WS2812 driver: https://cdn-shop.adafruit.com/datasheets/WS2812.pdf WS2812驱动程序的文档： https ://cdn-shop.adafruit.com/datasheets/WS2812.pdf
Tutorial on how to use LED strip with WS2812 driver: https://tutorials-raspberrypi.com/connect-control-raspberry-pi-ws2812-rgb-led-strips/ WS2812驱动程序如何使用LED灯条的教程： https ://tutorials-raspberrypi.com/connect-control-raspberry-pi-ws2812-rgb-led-strips/
The tutorial is great as covers every step of the process. 该教程很棒，涵盖了该过程的每个步骤。 They end up using the rpi_ws281x python wrapper which has been compiled from c. 他们最终使用从c编译的rpi_ws281x python包装器。
