I2C总线存储器24c02驱动程序（KEIL）-memory 24c02 I2C Bus Driver (KEIL)

用89C2051实现高精度Sigma-Delta ADC变化-89C2051 realize with high precision Sigma-Delta ADC changes

基于8051单片机的模拟PS/2键盘的驱动程序，使用keil c51编译。-based on the simulation of 8051 PS/2 keyboard-driven procedures, the use of c51 Keil compiler.

实现钟表的基本功能，可以通过串口改时间，有记星期的功能，也可通过键盘改点-it can realize a clock s function ,can modify it s clock via serial and keys.can remember wenkends,

实时时钟芯片DS1302采用串行接口，只需3根引脚便可以完成操作，其使用非常方便。这里采用AT89S52单片机作为外部微处理器，来对DS1302进行控制-Real-time clock chip DS1302 serial interface, only three pins will be able to complete the operation, its use very convenient. AT89S52 microcontroller used here as an external microprocessor to control of the DS1302

利用NXP的新一代高集成度的芯片RC500完成Mifare系列卡的读写-The use of a new generation of highly integrated NXP" s Mifare chip RC500 Series completion card reader

51单片机开发的8道门出入记录控制板，具有RTC时钟功能，同时具有声光抱紧，能实时的记录被监控门的打开时间。本案例只有8路，但可以方便的扩展至32路。-51 MCU development of 8 door access control panel recorded with RTC clock function, both sound and light to hold fast, can be monitored real-time record of the time the door opened. This case is only 8-way, but can be easily extended to 32.
