基于EDA的LED屏下位机系统设计

为了开发LED信息显示屏系统，对LED单行显示屏下位机系统进行了研究，利用EDA软件PRO-TEUS建立了基于51单片机的硬件电路原理图，同时在KEIL环境下编写了相应的单片机通信和控制程序。经PROTEUS与KEIL的联合仿真和调试，证明了设计的可行性，开发出了包含从上位机接收字符信息并储存在下位机存储器中的串口通信部分和从存储器读出字符信息并显示的显示控制部分的显示屏下位机系统。

Design of LED display controller system based on EDA

In order to develop LED information display system, research of LED single - lined display controller system has been carried out, developed schematic circuit diagram based on 51 single -chip controller using PROTEUS which is an EDA software, at the same time, single - chip controller related communicating and controlling program has been developed under the KEIL environment. Through the joint simulation and debugging in PROTEUS and KEIL, Proved the feasibility of the design, and devoloped the controller system of the information display system including serial pert communication part that receiving character information from the computer and storing it in the memory of controller system and display controlling part that read the character information from the memory and displaying it.
