Virtual serial port screen simulation system and simulation method thereof

Abstract

The invention discloses a virtual serial port screen simulation system and a simulation method thereof. The virtual serial port screen simulation system comprises a resource reading module, a display driving module, a touch screen driver, a serial port communication module, a command processing module, a storage module and a main program module, wherein the resource reading module provides an interface for reading an image resource, a font library resource and a system configuration resource, the display driving module provides a display-related interface, and the touch screen driver realizes touch compression action detection and reads touch coordinate parameters; the serial port communication module provides an interface for receiving and transmitting data by virtue of a serial port and records communication historical data; the storage module is used for storing system parameters and a control state of a serial port screen; and the main program module builds the modules into a complete and executable program. The virtual serial port screen simulation system has the advantages that a developer can directly complete development and debugging of the serial port screen on a PC, the resource is avoided from being repeatedly downloaded to the serial port screen for many times, and time of the developer is saved.

Description

technical field [0001] The invention relates to a simulation system and a simulation method thereof, in particular to a virtual serial screen simulation system and a simulation method thereof. Background technique [0002] The serial port screen is a kind of liquid crystal display device, which communicates with other single-chip microcomputers or programmable devices by sending and receiving commands through the serial port. The early versions of serial screens simply downloaded pictures and fonts through a PC software, and then sent commands to display various interfaces that need to be displayed to achieve the required display effect. [0003] At present, the serial screens of some manufacturers already support the configuration function, and the interface display effect can be designed visually through the PC configuration software, and the interface operation is getting closer and closer to some mobile phone software. However, for developers of serial screens, in the p...

Problems solved by technology

However, for serial screen developers, in the product design and debugging stage, it is still necessary to download resource files such as pictures, fonts, and touch configurations through various interfaces. During the development process, these files usually need to be repeatedly modified and adjusted, and then downloaded again. very time consuming

Moreover, developers cannot directly observe the serial communication data records, and the debugging process is more difficult.
