2.3 Functional requirements analysis
Requirements analysis is a very important process in the software life cycle. It determines the quality of the entire software project and is also the success or failure of the entire software project. It is required that all functions of the software can be used normally and the interface is beautiful.
2.3.1 Equipment module
The device module of the debugging assistant mainly allows users to create and delete devices. For creating devices, users can choose to create TCP type clients and servers or UDP type clients and servers. Serial device is automatically detected and created. For deleting a device, the created device is deleted. The activity diagram for creating the device is shown in Figure 2-2.
