Description: 目前市场上不少的单片机具有ISP功能。
ATMEL公司最近新推出的AT89SXXXX系列单片机也提供了一个SPI串行接口,让用户能对内部程序存储器编程（ISP）。
什么是 ISP ?
ISP（In-System Programming）在系统可编程，指电路板上的空白器件可以编程写入最终用户代码， 而不需要从电路板上取下器件，
已经编程的器件也可以用ISP方式擦除或再编程。ISP技术是未来发展方向。
应一些单片机爱好者的需求,现介绍本站开发的利用串口对89S51及89S52 ISP编程的软件及最简单的硬件连接方法．
下图是个简化了的硬件连接方法,虽然不能全自动的在线编程，但其连接简单实用稳定，比较适于初学的爱好者DIY

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
