MCU:PIC18F4550.实现了USB数据传输模块的设计，由于windows为HID提供了完整的类驱动程序及相应的API，因此开发PC端的HID应用只需调用API即可完成，作为嵌入式开发的工程师只要熟悉C++即可独立开发相关的上位机程序，无需在为协作开发中一人上位机、一人下位机的配合冲突而烦恼。-MCU: PIC18F4550. To achieve the USB data transfer module design, the windows to provide a complete HID class driver and the corresponding API, so the PC side of the HID application development just call the API to complete, as long as the embedded development engineers familiar with C++ can be independently developed PC-related procedures, without the need for collaborative development in one PC, one person with the next crew of the conflict and trouble.
