摘要
在单片机课程设计中引入Proteus仿真软件,结合Keil C语言,以AT89C51单片机为核心,设计了能对任意信号频率进行大量程、高精度测量的测频系统,详细分析了频率测量误差的形成原因及过程,针对性地提出了改善测频精度的方法,并在Proteus仿真中予以验证,获得了良好的教学效果。
Combining Proteus and Keil C On subject design of microcomputer. Takes AT89C51 as the core, designs the long-range precision frequency-measuremen instruments of arbitrary signal. The paper analyses the reasons and process of resulting error in the frequency measurement and put forward the method of improving the accuracy of frequency measure, and verifies by simulation using Proteus software, wins better effect for teaching of Microcomputer.
