在提高硬件系统抗干扰能力的同时，软件抗干扰以其设计灵活、节省硬件资源、可靠性好越来越受到重视。下面以MCS-51单片机系统为例，对微机系统软件抗干扰方法进行研究。-Improve hardware system in the anti-jamming ability, anti-jamming software for its design flexibility, save hardware resources, increasing reliability of good attention. Below MCS-51 single-chip microcomputer system as an example, computer system software for anti-jamming methods.

pc端usb下载程序DNW的源代码，配合开发板usbd程序可以实现pc和开发板互通-usb client pc download the source code of DNW, with the development board can USBD pc and realize mutual development board

ds1302的单片机程序实现，适用51的时钟芯片-ds1302 the SCM program, the application of 51 clock chips

以上程序使用PIC12C508单片机，内部4MHZ时钟，4脚输入50HZ脉冲信号，7，6，3脚（GP0，GP1，GP4端口）为输出口。其中渐变部分是让灯慢慢的变亮（或灭--It uses PIC2C508 SCM, 4MHZ clock, 4 port is for inputting 50HZ signal, 7/6/3 port for output.
