该文档分为两部分，第一部分是51系列计数器的一个程序，设计到开关中断，实现计数功能，计数到178；第二部分是一个频率，实际上也是对51单片机中计数器的一个应用，并且结合了驱动数码管的功能，是一个很好的中断控制，与外设控制相结合的一个程序。

本程序是原创流水灯程序，初学者很好的学习用，使用verilog编写的程序。流动led实验。

基于S3C2440和Linux的嵌入式网络驱动程序开发-Based on S3C2440 and Linux driver development for embedded networking

pwm电机步进控制，可以按键控制，功能完善，有兴趣者可以进一步交流。-pwm stepper motor control, can be key to control, functional improvement may have interest in further exchanges.

Linux 操作系统提供进程间通信（IPC）机制，用来保证正在执行的进程在内核的协调下能够 共享资源、同步以及交换数据等。Linux 支持大量进程间通信机制，包括信号、等待队列、管道 以及Unix 系统V 中提供的进程间通信机制，如消息队列、信号量和共享内存。-Linux operating system to provide inter-process communication (IPC) mechanism used to ensure that the process is being implemented in coordination with the core to share resources, synchronization and exchange information. Linux support a large number of inter-process communication mechanisms, including signal and wait for the queue, pipeline and the Unix System V to provide inter-process communication mechanisms, such as message queue, the signal volume and shared memory.

在89C51芯片上运行，采用两个中断方式，一个外部0中断实现救护车通行，南北红灯10秒后恢复中断前状态，另一个是定时器0中断实现南北灯状态转换，16X16 LED点阵对应显示“南北”字样信息-89C51 chip in operation, interruption of the use of two methods to achieve an external 0 interrupt the passage of ambulances, the North-South red light 10 seconds after the resumption of state, and the other is the timer 0 interrupt to achieve the state of North-South light conversion, 16X16 LED dot-matrix corresponding show " South-North" in the information
