做一个电子钟：利用定时器0定时中断，控制电子钟走时；利用单片机上的六个数码管显示时、分、秒。-An electronic clock to do: Using Timer 0 interrupt timing, control of electronic bell away the use of the six single-chip digital display hours, minutes and seconds.

本人设计的用802051实现的键盘程序的识别代码。系统采用定时查询，防抖。如果监测到你一个代码，系统将键盘码输出。然后给我你个中断，用于提示中心机，读取键码。支持长按。-I designed keyboard with 802,051 procedures to achieve the identification code. System uses a regular query, Anti-Shake. If the monitoring to you a code, the system will output the keyboard code. And then give me interrupt you for the prompt Center machine, read the key code. Support the long press.

自己用C语言编的一个看门狗，由于刚学单片机，写得功能比较简单-Own use C language compiled a watchdog, as just learning microcontroller, written in relatively simple function

The New Computerised Transit System (NCTS) is a European wide system, based upon electronic declaration and processing that was designed to replace the paper based CT system and to provide better management and control of both Community and Common Transit. It involves all EU Member States and the EFTA. The NCTS in each country is connected through a central domain Brussels, to all of the other countries. This provides links between some 3000 European customs offices and replaced the paper based system. In order to connect on-line with NCTS, traders need the facility to generate electronic Transit messages, and the facility to send/receive these messages to/from the IRL - NCTS. Connected traders receive electronic responses advising of key decisions during the procedure, such as acceptance of declaration, release of goods, notification of discharge. It is not be possible for Traders to interface directly with NCTS. They will simply be able to exchange defined structured m
