QT weekly skills (3)~~~~~~~~~ serial port addition

前言

    上次写了Qaction的添加,Make the interface look better,This time, add the serial port settings required by the project,This part is actually more like a gourd,别人怎么做,Just do it yourself.

第一节

    Directly on the finished picture to see the effect,Continue below if necessary.

    初始界面：

     Click on the setting interface：

     screen after connection：

     点击下载后,The virtual serial port receives the data interface：

 第二节

    add points：

（1）Serial port element added;

（2）Serial port setting interface added;

（3）全局变量添加;

    下面大概说一下：

串口：Serial port requiredclass已经包含在QT的库里面,所以可以直接调用函数.

添加位置：（1）profile to add the core file;

                 （2）mainwindowThe header file adds the serial port header file;串口类,分别为​：

                         #include <QSerialPort>

                         QSerialPort *m_serial = nullptr;

                 （3）mainwindowThe main file adds class files​,分别为：

                          m_serial(new QSerialPort)

串口设置界面​：The serial port setting interface needs to be addedui工程,How to add this is described earlier​.

添加位置​：（1）mainwindowThe header file adds the serial port header file;分别为​：

                         class serialset; 

                         serialset   *m_serialset = nullptr;

                 （2）mainwindowThe main file adds class files,分别为：

                         m_serialset(new serialset)

全局变量​：Global variables are used in the same way as microcontrollers,After adding the correspondingclass删掉就行,然后在需要调用的​A header file that contains global variables in the file will do.这样全部的​A file can use a variable.Although in object-oriented programmingGlobal variables are discouraged,但是Don't stick to your frame,Most of the small partners should come from logic programming,You should be used to using global variables,Just remember where to change the parameters when you use it yourself​.

结语

    The following article will add a lot of serial port data processing and bit by bitcan数据处理方法,And use a simple screen to achieve​.The program in the Baidu network disk is only the first time I have written itQTinterface is implemented,It's still a little bit bad now,So slowly improve the previous program,At the same time, add the problem of testing the number of serial ports received,For source code programs, please pay attention to the subscription number,Added Baidu network disk connection to the corresponding article in the subscription account,可以直接下载源代码.

     The file cannot be sent due to the subscription number,So if you need source code, please leave a message​.At the same time, the subscription account cannot send messages to the following friends first,You can only reply to the messages sent by your friends first,So friends who need source code, please leave a message in the public account.​
