USB接口与上位机软件设计

USB Interface and Upper Computer Software Design

USB接口一般用于高速数据采集或传输任务中,是计算机和硬件设备系统之间的通讯管道,既可以完成数据传输任务,也可以实现计算机对设备系统的控制。该文设计和开发了工作在Slave FIFO模式下的通用USB接口和配套的上位机人机界面软件,以满足单片机、DSP、FPGA等微处理器与上位机之间的高速、稳定的数据传输需求。该设计开发的上位机人机界面能实现向下发送特殊控制指令的功能,并且经过实验结果表明,该设计能够满足较高速的数据传输工作,可以用于一般的测量和传输工作。

USB interface is generally used in high-speed data acquisition or transmission tasks.It is the communication channel between the computer and the hardware system,which can not only complete the data transmission task,but also realize the control of the computer to the equipment system.This paper designs and develops the universal USB interface and supporting man-machine interface software of upper computer working in Slave FIFO mode,so as to meet the high speed and stable data transmission demand between microprocessors such as MCU,DSP,FPGA and upper computer.The man-machine interface of the upper computer developed by this design can realize the function of sending down special control instructions,and the experimental results show that this design can meet the needs of high-speed data transmission work,can be used for general measurement and transmission work.
