Besides GUI, the software also contains rich extended functions such as business logic of error tester and external instruction communication.
In addition, as shown in fig. 7, the embodiment of the present application provides an interface tuning state diagram applied to an error code testing system. Specifically, interfaces are functionally classified into four categories: a channel configuration interface, a test interface (main interface), a system setting interface and a shutdown interface. The skipping and the specific operation of each interface can be realized by simply clicking a touch screen. In addition, in order to ensure that the error code tester can be started successfully, the physical keys of the power button are reserved in the embodiment of the application, and all operations of the error code tester can be completed through an 8-inch capacitive touch screen except for the starting operation.
