import{Playbulb}from'https://unpkg.com/jcode-bluetooth@0.1.0/dist/jcode-bluetooth.js';constdevice=newPlaybulb();constbutton=document.querySelector('button');functionsleep(ms){returnnewPromise(resolve=>setTimeout(resolve,ms));}button.addEventListener('click',async()=>{awaitdevice.connect();lethue=0;while(true){awaitdevice.setColor(`hsl(${hue}, 100%, 50%)`);hue=(hue+1)%360;awaitsleep(100);}});
因为Pixoo系列像素板的蓝牙协议是SPP，浏览器Web Bluetooth只支持GATT，所以需要启动本地HTTP服务做一个代理。
准备好设备，通过手机蓝牙调试工具查看设备地址，然后clone本项目到本地，安装依赖后启动server服务：
npm install&& npm run server --<设备MAC地址>
接着就可以在Web上编写代码了，Pixoo对象提供了可操作的canvas对象，你可以直接操作这个对象，绘制内容会自动同步到设备上。
import{PixooMax}from'https://unpkg.com/jcode-bluetooth@0.1.0/dist/jcode-bluetooth.js';constp=newPixooMax();constctx=p.canvas.getContext('2d');ctx.fillStyle='green';ctx.fillRect(8,8,24,24);
