The serial port is called a serial interface, also known as a serial communication interface. According to electrical standards and protocols, it includes RS-232-C, RS-422, RS485, USB, etc. The RS-232-C, RS-422 and RS-485 standards only specify the electrical characteristics of the interface and do not involve connectors, cables or protocols. USB is a new interface standard developed in recent years and is mainly used in the field of high-speed data transmission.
At work, we often use the serial port to read and write data. Today we are going to make a serial port tool ourselves. In this section, we first build the basic framework.
1. Environment configuration
1. Here I use Qt Designer directly to design the layout of the serial port interface.
(1) First, let’s make the port selection of our serial port, as well as the baud rate, serial port switch, etc.:
Several controls such as groupBox, label, comboBox, and pushButton are used here.
(2) Next, make our serial port advanced settings part:
(3) Then there is the serial port data sending part:
There are two types here, ASCII and HEX types.
(4) Including data sending and receiving text boxes:
(6) Toolbar production:
It includes four functions: file, settings, help, and exit.
(7) The final layout is as follows:
2. Generate the corresponding .py file

This article will first talk about the production of the basic framework, and the next issue will talk about how to implement the functions.
