这是一段开始学单片机时写的LCD程序，基于普通的51单片机，在KEIL环境上开发的。...

C51单片机的非常好的实例，播放音乐，好好学习-C51 MCU very good example of music, to learn

LCD1602的驱动代码（头文件） 用mega16单片机实现-LCD1602 driven code (the first) with mega16 MCU

用485实现单片机之间的串行通信。 从机部分一直等待主机的命令，接收到就发响应信号，然后接受数据，接受成功就用液晶显示-MCU with 485 Serial Communication between. From the plane of the mainframe have been waiting for the orders received on the response signal and then receive data on the successful use of acceptable LCD

基于飞思卡尔16位单片机的用以实现液晶显示程序-LCD display

单片机定时器的应用，通过对专用寄存器的设定，完成定时计数功能！-Application of single-chip timer, by setting a dedicated register, complete the count function from time to time!

本文详细系统地介绍了uC/OS-II 在51 单片机上的移植、重入实现方法、硬件仿真、固化、人机界面等关键内容。-paper detailed and systematic introduction of the Phone/OS-II in 51 MCU transplant and re-entry method, hardware simulation, curing, the man-machine interface and other key elements.

该时钟以24小时制显示时间，并可显示2000年至2049年之间的任何日期及星期，日期与时间经按键可相互切换，可输入8个闹钟时间设置，每个闹钟设置包括响铃的时间（小时与分钟）、对工作日有效还是对周末有效的标志，以及本项设置是否启用的标志等三部分。这8个闹钟设置均保存在EEPROM中，即使掉电也不用重新输入。-The 24-hour clock to display time, and shows from 2000 to 2049 and any date between the weeks, the date and time as may be mutually switch button, enter the eight alarm time settings, each set including the ringing of an alarm clock Duration (hours and minutes), the effective working days or weekends effective road signs, as well as whether or not to enable this setting, such as a symbol of three parts. This 8 alarm settings are stored in EEPROM, even brown-out do not have to re-enter.

次程序为单片机89S51系列温度传感器部分程序.-meeting procedures SCM 89S51 series temperature sensors some of the procedures.

使用VB编写的上机位的串口控制,我的串口搞定与大家一起分享快乐.上位机是用VB编的. 我想告诉大家是:其实串口通信也不是什么很难的事,只要用心去搞一定能作好的. -VB prepared on the use of machine-bit serial control, serial port I get to share their happiness with you all. PC is VB series. I want to tell you is: In fact, serial communication is not a difficult thing, as long as intentions to engage in will certainly be able to prepare for.

采用UART方式0与LM74通信。 用C8051f020的P0.7作片选，主机通过TXD发送时钟信号，实现同步通信,半双工.RXD 作双向数据线.用六位数码管显示LM74采集的温度值-The use of UART communication mode 0 and LM74. P0.7 used for the C8051F020 chip select, host TXD sent through the clock signal, to achieve synchronous communication, half-duplex. RXD for bi-directional data line. With six digital tube display LM74 temperature collected
