摘　　要：USB设备及其驱动程序的复杂性给开发人员带来了很大的开发难度。提出了基于LPC2378为核心的USB硬件接口和HID类的USB通信接口固件程序的设计方法,并利用Visual C++6.0开发环境对HID类的支持特性,完成主机应用程序快速、高效开发。接口试验表明,主机与设备之间数据传输稳定可靠。Development of USB interfaces is challenging because of the complexity of the USB device drivers. This paper intro duces a method alleviating the difficulty, taking the advantage of LPC2378-centered hardware and HID-class oriented firmware. Visual C＋ ＋ 6.0 supports HID class so the USB communication interface can be completed without much difficulty. Tests show that the communication through developed interfaces is stable and reliable.
