摘　　要：通用串行总线因(USB)具有传输速度快、即插即用、易于扩展、占用系统资源少等优点;嵌入式实时操作系统(RTOS)中的μC/OS-Ⅱ则具有代码效率高、占用空间小、良好的实时性和可靠性等特点。本文通过构建嵌入式软件开发环境、移植μC/OS-Ⅱ、编写固化到ATmega16单片机的引导程序(即固件程序),实现系统的数据采集、数码显示以及与PC机通信等设备端任务。The hardware platform of the system consists of high-Performances 8-bit AVR series microcontrollerATmega16 as the core, USB controller PDIUSBDI2 supporting USB Specification Revision1.1 and other periphery devices. By setting up embedded system developing environment, replanting μC/OS-Ⅱ and developing the firmware program for ATmega16, the tasks of data acquisition, code display and communicating with personal computer are completed.
