The load font from buffer would be a good idea if I could directly pass a buffer to the load function for a font. With an image I am able to pass a filename,lv_img_dsc_tstructure or an array of bytes that contains the image data. The only thing that can be passed to the load...
只有在连接到蓝牙设备并使用特征值注册了read、write、notify监听后才算连接成功。 在扫描周围设备时,可按自定义的规则过滤多余设备,连接指定设备。详见示例lb-example-bluetooth-manager.js。 新增蓝牙协议配置文件,可以很方便的发送和接收蓝牙协议。 小程序退入后台会自动缓存要发送的协议,待回到前台后重新发送(如果小...
I have been lucky enough to work with thousands of good developers over the years who wanted to learn how to write more secure software. During this time, I've also learned a great deal from people who are very good at building secure systems, and this got me th...
Peerobjects are instances ofstream.Duplex. They behave very similarly to anet.Socketfrom the node corenetmodule. The duplex stream reads/writes to the data channel. varpeer=newPeer(opts)// ... signaling ...peer.write(newBuffer('hey'))peer.on('data',function(chunk){console.log('got a chu...

Give your Linux box a multicolored light you can see from across the room, and learn how to write a simple driver for the next piece of hardware you want to hook up. Since this column began, it has discussed how a Linux driver writer can create various types of kernel drivers, by exp...

it does not directly trigger computing but puts the data into a Buffer. When the Buffer is full, the computing starts. The data in Buffer is grouped by key and calculated by each group. For each key, the previous aggregation results corresponding to the key are obtained from the state, an...
