用ARM7微处理器实现LED显示
Realizing the Display of LED by ARM7 MPU
【摘要】 介绍了嵌入式系统发展的现状。分析了基于ARM7微处理器S3C44B0系统中八段数码LED显示的实现原理,探讨了S3C44B0与LED的硬件接口设计和软件设计,给出了硬件连接图和部分程序代码。并通过实验验证了八段数码管能循环显示0~F字符。
【Abstract】 The developing status quo of Embed system is introduced.The principle of display of 8-SEG LED based on ARM7 MPU S3C44B0 is analyzed,design of software and hardware interfaces between S3C44B0 and LED are discussed,the hardware interfaces chart of S3C44B0 and LED and part of program are offered.The result that the 8-SEG LED can circularly display from 0 to F is validated by experiment.
