摘要
为了解决大屏幕显示牌控制稳定差、不便捷等问题,本文分析了大屏幕点阵的运行原理,提出基于MCS51单片机的大屏幕显示牌的控制设计。控制模块中,采用Wi Fi将单片机和终端进行无线连接,通过终端对显示牌进行控制;显示模块中,通过串行输出解决I/O不足的问题,并采用74HC595将串行数据转换为并行数据,点亮点阵屏。整套系统节省了I/O口资源,并在控制方式上做出了创新,使得控制方式更加稳定、快捷。
In order to solve the problem of poor stability an d inconvenience for controling the large screen display card, this paper analyzes the operation principle of large screen lattice, and proposes a control design of the large screen display card based on MCS51 single-chipmicrocomputer. In the control module, this paper connects the single-chip microcontroller and the terminal wirelessly through the Wi Fi, and controls the display card by the terminal. In the display module, this paper solves the problem of lacking I/O by the method of serial output, and uses 74HC595 to convert serial data into parallel data. Then the lattice screen is lighted. This system saves the resources of I/O, and makes change in the control method, making control method more convenient and fast.
