【花雕动手做】ASRPRO语音识别（41）---64位WS2812B点阵屏模块

eagler8

本例实验使用64位WS2812点阵屏模块

知识点：WS2812B

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。

数据协议采用单线归零码的通讯方式，像素点在上电复位以后，DIN端接受从控制器传输过来的数据，首先送过来的24bit数据被第一个像素点提取后，送到像素点内部的数据锁存器，剩余的数据经过内部整形处理电路整形放大后通过DO端口开始转发输出给下一个级联的像素点，每经过一个像素点的传输，信号减少24bit。像素点采用自动整形转发技术，使得该像素点的级联个数不受信号传送的限制，仅仅受限信号传输速度要求。

LED具有低电压驱动，环保节能，亮度高，散射角度大，一致性好，超低功率，超长寿命等优点。将控制电路集成于LED上面，电路变得更加简单，体积小，安装更加简便。

WS2812B主要特点

1、智能反接保护，电源反接不会损坏IC。

2、IC控制电路与LED点光源公用一个电源。

3、控制电路与RGB芯片集成在一个5050封装的元器件中，构成一个完整的外控像素点。

4、内置信号整形电路，任何一个像素点收到信号后经过波形整形再输出，保证线路波形畸变不会累加。

5、内置上电复位和掉电复位电路。

6、每个像素点的三基色颜色可实现256级亮度显示，完成16777216种颜色的全真色彩显示，扫描频率不低于400Hz/s。

7、串行级联接口，能通过一根信号线完成数据的接收与解码。

8、任意两点传传输距离在不超过5米时无需增加任何电路。

9、当刷新速率30帧/秒时，级联数不小于1024点。

10、数据发送速度可达800Kbps。

11、光的颜色高度一致，性价比高。
