The ADC0803 family is a series of three CMOS 8-bit successive approximation A/D converters using a resistive ladder and capacitive array together with an auto-zero comparator. These converters are designed to operate with microprocessor-controlled buses using a minimum of external circuitry. The 3-State output data lines can be connected directly to the data bus.

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.

51做的门禁系统代码，有4×4键盘扫描，9346的存储功能，掉电不丢失密码，3重密码防忘记功能-51 of the Access Control System code, a 4 4 keyboard scanning, the 9346 storage functionality, nonvolatile not lost password, three heavy-forget the password function

电机调速的控制程序，你可以通过这个程序来设定参数，通过反馈就可以控制速度了啊！-of motor speed control procedures, you can use this procedure to set parameters, feedback can control the pace of their ah!

原创的XML解析，不过只能解析节点及节点内容，不支持属性，纯C语言，适合嵌入式系统使用。-Original XML parsing, but only parse the contents of nodes and the node does not support attributes, pure C language, suitable for embedded systems.
