【摘要】 专用USB芯片能够实现具有特定功能的嵌入式系统与主机进行数据传输,但可能会导致增加成本。现今,以ARM为内核的微处理器不仅集成了USB功能,还具有诸多其他强大的功能,使开发者在设计自己的系统时更灵活、省事。LPC2148具有2K终端USBRAM,512K片内Flash,是适用的USB开发芯片。利用LPC2148微处理器USB器件模块的软件接口与USB协议层软件之间的联系,实现LPC2148处理器USB器件与主机之间的通信,完成数据的传输。更多还原

【Abstract】 It may cause the increasing of the cost if using special USB chips in the embedded system which in order to complete the data transition function between embedded system and PC. Recentl y, more and more micro-processors with ARM cores not only integrate USB function, but also include many other strong functions. Those micro-processors make the exploitations flexible and convenie nt. LPC2148 with 2K endpoint USB RAM and 512K inside flash is suitable to USB exploitation. Utilize the relationship between the software interface of USB device block of LPC2148 micro-processor to realize the communication from LPC2148 micro-processor to PC and complete the data transition.更多还原
