主要讲了单片机是实现仿真国际象棋的功能。十分好。

串口485通信的好范例子，在工程实践已经调试过了的，抗干扰性好-A good example of serial communication sub 485, in the engineering practice has been passed to debug, and anti-jamming good

基于单片机c8051F020开发环境下的计数器程序代码-C8051F020 development environment based on the single-chip counters under the code

AD 转换 用定时器中断 显示 0--5V-AD0804 zhongduan xianshi

本装置是一个以HT46R71D 为主芯片，配合传感器组成的汽车轮胎气压检测装 置，最终取高三位有效值于LCD 显示，有四种显示单位供切换（Psi、Bar、Kpa、 Kgf/cm2）。本装置仅为参考范例，使用时，为提高准确度，建议多量测些组数 据来构建Sensor Output Voltage - Discharge Time (V-T)表格，并作相应校准。-This device is a HT46R71D-based chips, with sensors detecting vehicle tire pressure devices, and ultimately take the high-three RMS in LCD display, there are four types of display units for switching (Psi, Bar, Kpa, Kgf/cm2). Only reference to an example of the device, when used to improve the accuracy of the proposed多量measured set of data to build more Sensor Output Voltage- Discharge Time (VT) forms, and the corresponding calibration.

本程序是用 ATmega16 控制实时时钟芯片 DS12887 接口驱动的源程序文件。-this procedure is used to control real-time clock ATmega16 DS12887 interface-driven source files.

C51 Timer 0 的使用 Timer_0_mode_0_timer_gate_hard -C51 Timer 0 use Timer_0_mode_0_timer_gate_hard

用keil C编写绝对原创 内有proteus的仿真文件。可以实现时间的重设闹钟的设置，到时间后有警告。-Keil C used in the preparation of absolute originality has Proteus simulation file. Can realize the time to reset the alarm clock settings, and has warned that time.

c 51编程的一个教训，抛出一个范例是为了然大家吸取教训。-programming a lesson dished out an example to everyone ran to learn.
