Description: 频率测量，对于周期波频率的测量方法很多，但大多是通过测量间接计算频率。本文介绍了用目前应用比较广泛的MCS-51系列单片机对周期波频率进行测量，并通过LED以数字形式直观地示出频率，实现测量的智能化，省去间接对频率计算的麻烦与错误。文章对其测量原理、设计和实现作了说明，并进行了误差分析-Frequency measurement, the cycle frequency of the measurement method, but are calculated indirectly by measuring the frequency. In this paper, compared with the current application of a wide range of MCS-51 series single-chip frequency of the periodic wave measurements, and in digital form through the LED to visually indicate the frequency, the realization of the intelligent measurement, indirectly saved the trouble of calculating the frequency and错误. Article of its measuring principle, design and realization of an explanation, and the error analysis

Description: 该设计使用的是AT89S52单片机构成的波形发生器，AT89S52是一个低功耗，高性能CMOS 8位单片机，片内含4k Bytes ISP(In-system programmable)的可反复擦写1000次的Flash只读程序存储器，器件采用ATMEL公司的高密度、非易失性存储技术制造，兼容标准MCS-51指令系统及80C51引脚结构，芯片内集成了通用8位中央处理器和ISP Flash存储单元，功能强大的微型计算机的AT89S52可为许多嵌入式控制应用系统提供高性价比的解决方案。所以利用其产生三角波、方波、正弦波等多种波形，波形的频率可控制改变，波形清晰、频率调整十分方便、稳定性好，产生较复杂的波形只须修改源程序，不需要改装电路．在单片机的输出端口接DAC0832进行DA转换，再通过运放进行波形调整，最后输出波形接在示波器上显示。本设计具有线路简单、结构紧凑、价格低廉、性能优越等优点-The dissertation is usage of the AT89S52。 The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 4K bytes of In-System Programmable Flash memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 instruction set and pin. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with In-System Programmable Flash on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications. Single-chip microcomputer constitute of wave-form generator, which can generate triangle wave, square-wave, sine wave etc. Variety wave-form, the period of wave can be controlled .The wave form is explicit，with good frequency adjustment and stability performance．Only by varying its software，not hardware，it
