摘要
针对传统移位式霓虹灯扫描控制器的缺点,研制出由8031单片机、EPROM2732程序存储器和输出锁存器等组成的通用型可编程霓虹灯扫描控制器。文章介绍了该控制器的硬件电路和工作原理,给出了印刷电路板的制作方法和软件编制步骤。该扫描控制器可实现任意一种用户要求的扫描花样,具有很大的实用性。
To improve the shorting of the traditional displacing neon lamp scanning controller,a general purpose programmable scanning controller for neon lamps is developed on the basis of 8031 single chip micro computer,EPROM 2732 and output latch.This article describes the hardware circuit and operation principle of the controller,and the make of the PCB and the programming procedure are also given,this controller is very practical and can realize any scanning pattern to satisfy the needs of clients.
