其中的usb端口通信已经作为一个模块来使用，用户只需用以下函数就可以对usb端口进行方便地读写： unsigned char D12_WriteEndpoint(unsigned char endp, unsigned char len, unsigned char * buf) 此为usb端点输出函数，endp是要进行通信的端点，取值为3（普通端点，最大可一次传输16byte）或5（主端点，最大可一次传输64byte）；len为一次输出数据长度；*buf为数据所在位置。 usb端点数据的读操作是由底层函数自动完成的（相关函数为unsigned char D12_ReadEndpoint(unsigned char endp, unsigned char len, unsigned char * buf)； 相应端点为2和4），所读到的数据存于GenEpBuf[]（普通端点）、MainEpBuf[]或EpBuf[]（主端点）中，用户可以直接读取使用。-Usb port communication which has been used as a module, the user can use the following function on the usb port can easily read and write: unsigned char D12_WriteEndpoint (unsigned char endp, unsigned char len, unsigned char* buf) This is the endpoint usb output function, endp is to communicate the endpoint, the value for 3 (common endpoint, the first transmission maximum 16byte) or 5 ( the main endpoint, the first transmission maximum 64byte) len Length of output data for the first time * buf location for data. usb endpoint data is read

基于89s51的keil跑马灯工程，程序虽然简单，但是它的经典程度不亚于软件开发中的“hello word”，单片机汇编编程者不妨参考一下。内附proteus完整的仿真文件。-Based on the keil Marquee 89s51 works, the program is simple, but it is no less than classic software development in the " hello word" , the compilation of single-chip programmers may wish to reference.
