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
