Design and Simulation of Dot-Matrix Display Circuit Based on Proteus in Single Chip Microcomputer

摘要

This paper introduces display design process about hardware and software based on Proteus in single chip microcomputer. We use a simple external circuit to control the display screen, which size is 16 × 80. The display screen also can display the size of the five 16 × 16 dot matrix Chinese characters by a dynamic scan mode, and we can modify the code to change the content of the display, subtitles can achieve scrolling function and the scroll speed can be adjusted according to requirements. The Chinese character code stored in external data memory, the capacity of data memory is expanded according to the requirements of Chinese characters we want to show. Finally, the circuit which has been designed was simulated on the basis of Proteus. Simulation results show the Proteus software application is an important practical value in the design of single chip microcomputer, which will greatly shorten the development cycle and save development costs.
