51控制DS1302时钟源代码 程序

该程序完成了c8051外围电路的驱动和串口协议的编写。希望能给大家学习51单片机带来帮助-The program was completed C8051 driver peripheral circuits and serial protocol to prepare. I hope everyone can learn from 51 Singlechip help

进行简单的无刷直流电机控制，带霍尔的，三相六状态，没加入PID，没加入过流、过压保护。比较适合初学者参考，

这是与ge 90-30通讯的教学，希望对大家有所帮助。-Ge 90-30 This is in line with the teaching of communication, I hope all of you to help.

工频正玄波的逆变器电路，成熟使用的方案，请用作设计参考，thx-frequency Shogen wave inverter circuit, the use of mature programs, please reference for the design, thx

这个是一个AD与DA的基于汇编的dsp程序 是CCS环境的-AD and DA based on the compilation of dsp procedures CCS environment

本文件含7022B的程序代码，用模拟SPI通讯，内部代码使用struct结构体互相联系。内部还有芯片介绍，方案例子，相关电力仪表论文等。可以把该文件视作为一个7022B的小资料库，内部含很多精华，希望给你带来帮助。

这些都是常用的通信设备的电路原理图，很多是高频电子线路的--Circuit diagrams for some commonly used communication devices. Many are operated under high frequency.

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.

usb的协议细节，网上有很多信息。
