1、Qt的应用开发 之 Demo_MessageChat_Qt Qt5气泡式聊天框——QListWidget+QPainter。 气泡式聊天的显示是由QListWidget作为控件，每个气泡是由QListWidgetItem提升成QWidget来实现的。每个气泡可以理解为可以自由布置里面内容的QWidget。每个Item保存聊天的对话、发送状态、时间、种类等。这个QWidget主要是显示一个头像+气泡，气泡里面是聊天的内容等。气泡是在paintEvent事件中，采用QPainter来绘制的。 2、更新信息 开发者：沙振宇（沙师弟专栏） 创建时间：2018-07-23 最后一次更新时间：2019-12-27 此项目CSDN博客：Qt5气泡式聊天框——QListWidget+QPainter实现 此项目博客地址： 3、效果

将这178个样本的50%做为训练集,另50%做为测试集,用训练集对SVM进行训练可以得到分类模型,再用得到的模型对测试集进行类别标签预测。

The MicroRWD MF LP (Low Power) module is a complete read and write solution for 13.56 MHz Mifare Classic cards (1k, 4k and Ultralight versions) and supports “Mifare” contactless operations to dual-interface cards such as Mifare ProX, Smart MX (JCOP) and other types. DESfire and Mifare PLUS cards are supported for serial number acquisition only. The solution is entirely housed within a 24-pin DIL package and only needs an antenna connected and a 5v DC supply to be a fully featured ISO14443A Mifare read/write system. The MicroRWD MF LP version behaves in the same manner as the standard reader except that it has an active, average current consumption of less than 150µµµ µA (micro Amps) with 1 second polling rate. As on other RWD modules, all commands and data response are via a simple TTL level RS232 interface. In addition, the RWD MF LP version has auxiliary data outputs on the OP0 / OP1 pins that can be programmed to automatically output UID (serial number) or other block data as asynchronous 9600 baud serial or Wiegand protocol Data High / Data Low signals. All these features can be configured and turned ON/OFF by setting RWD EEPROM parameters. The diagram below shows the pin out configuration for the MicroRWD MF LP module
