说明：  单线LED驱动程序。WS2812是一个集控制电路与发光电路于一体的智能外控LED光源。其外型与一个5050LED灯珠相同，每个元件即为一个像素点。像素点内部包含了智能数字接口数据锁存信号整形放大驱动电路，还包含有高精度的内部。振荡器和12V高压可编程定电流控制部分，有效保证了像素点光的颜色高度一致。
(Single-line LED driver. WS2812 is a set of control circuit and lighting circuit in one of the smart outside the control of the LED light source . Its appearance with a 5050LED same lamp beads , each element is a pixel . Pixels contained within the intelligent digital interface data latch signal shaping amplifier drive circuit also includes an internal precision . Programmable oscillator and 12V high-voltage constant current control section , effectively ensuring a high degree of color pixel light consistency .)
