本文介绍了一种电子密码锁的实现。该电子密码锁采用1一wire总线芯片Ds2401作为密匙，锁体采用高可靠性的单片机PIC16c63来完成密码识别和开锁控制，用I2C总线接口的EEPROM 芯片AT24c02来完成密码的存储和修改，可 掉电保存密码。整个系统安全可靠，稳定性高。-This paper introduces an electronic code lock realize. The electronic locks used one chip one wire bus Ds2401 as key, lock body for high reliability PIC16C63 microcontroller identification and password to complete the unlock control, with I2C bus interface EEPROM chip AT24C02 to complete the password storage and revised down to save the password. The entire system is safe and reliable, high stability.

CPU调度算法---模拟OS所使用的所有调度算法,包括创建一个kernel,PCB,队列，调度器等。-CPU Scheduler algorithms FCFS SJF Priority This code is a simulation of all the Scheduling algorithms an OS uses. I have tried creating a Kernel, PCB, Queue, Scheduler etc. what all an OS needs to run and execute a piece of code. Right now the code just displays the file given to in the input, If we modify the code so that it can interpret the meaning of the file then it can execute the file and can become a sub OS or VirtualMachine like JVM

洗衣机汇编程序，有四种洗衣模式：标准、经济、单独和脱水。-Washing machine assembler, laundry four modes: standard, economy, and dehydration alone.

此软件是PIC单片机的编程助手软件，你可以通过它来设定一些内部模块的使用情况(如定时器，SCI，CCP)等模块的设置。省去了人工去记这些设定值。设置完成后可以自动生成C源程序。 -this software is the PIC microcontroller programming software assistant, You can set it to the internal use of the module (such as Timer, SCI, CCP) module configuration. Save a manual to remember these values. After the completion of installation can be automatically generated C source files.
