基于高速SoC单片机在双基色LED屏中的应用

Application of dual color LED screen based on high speed SoC single chip

在以C8051F040作为微控制器的煤矿声光语言报警显示装置的前提下,讲述了C8051F040在双色LED屏中的应用,介绍了LED显示屏驱动方式、硬件电路、显示原理以及对单片机控制系统的基本要求和C8051F040的片内资源,给出了单片机与LED屏的硬件电路以及软件设计流程图和源程序。

On the premise that the coal mine language of sound and light alarm display device uses C8051F040 as controller, the paper describes the application of C8051F040 in two-color LED screen. It introduces the LED display drive, hardware circuit, display principle and the microcomputer control system＇s basic＇, requircments and on-chip resources of C8051F040. The paper gives hardware circuit of single-chip and LED screen, and also gives the software design flow chart and source code.
