一个很好的serial 串口演示代码，演示串口的读写功能-a good code for comm communication

LPC214xLPC_USB,固件程序,周立功的,就不用我评价了吧-LPC214xLPC_USB, firmware, Zhou Li-gong, and I would not have evaluated it

该工具用于数字电路仿真中的usb数据文件转换： 1.可以把11比特的令牌包数据（crc5）或者任意字节的数据包数据（crc16）转换为可以作为仿真输入的dn dp文件。 2.可以根据仿真接收到的dn,dp数据，解析得到接收的真正11比特令牌包数据或者数据包数据。 3.此为0.1版本，后续的版本更新会让该工具更完善。-The tool for digital circuit simulation usb data file conversion: 1. Can be 11-bit token packet data (crc5) arbitrary bytes of data or packet data (crc16) conversion could serve as a simulation input file dn dp. 2. Can be received in accordance with simulation dn, dp data analysis to be receiving the real 11-bit token packet data or packet data. 3. This is the 0.1 version update will follow-up version of the tool even better.

The UsbKbd example WDM device driver illustrates how to interrogate a USB device, specifically a USB keyboard.
