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

程序描述：使用Cypress的Cy7C68013A芯片进行设计，通过外接EEPROM来进行上电时的重列举。程序包括USB固件程序以及主机程序。 安装：把源码拷贝到硬盘特定目录下，使用Keil C编译器和Visual C++ 6.0运行即可。 注意：可以首先使用Cypress的调试工具进行固件程序的调试，以确保固件程序的正确性。 -Description: Using Cypress
