【摘要】 为了实现破片参数测量系统中上、下位机之间的USB接口通信,文中提出了一种基于PDI USBD12芯片的USB接口开发方法。该方法利用KEIL C进行固件程序开发、利用WinDriver进行驱动程序开发、利用C++Builder进行应用程序开发。实践证明这种开发方法大大降低了开发难度,缩短了开发周期。该方法对于其他USB接口的开发具有较高的参考价值。更多还原

【Abstract】 To realize the communication between upper machine and lower machine in fragment’s parameter measure system,a method of development is introduced base on PDIUSBD12 USB interface.In this method,firmware is developed using KEIL C,driver is developed using WinDriver and application program is developed using C++ Builder.In practice,these method help to simplify the development and shorten the period of development.This method can be referenced by other USB interface development.更多还原
