摘　　要：介绍了基于C8051F020单片机实现实时数据采集的软、硬件设计。给出了C8051F020单片机和CH375-USB主控芯片的技术特点。利用单片机内部的可编程控制的放大器将信号进行初步处理,设计了以C8051F020单片机作为处理器,通过控制CH375-USB主控芯片实现单片机对存储介质数据存储操作的数据采集系统,完成了USB设备写入的程序设计。This paper describes how to realize a real-time data acquisition system based on C8051F020, and its design of hardware and software. The technical characteristic of the C8051F020 single chip machine and the ch375 USB chip is given. The original signal will be amplified by a internal unit programmable control amplifier, the C8051F020 single chipmachine is used as the processor, and it can achieve the writing and reading of the storage medium, such as a USB flash drive, through the control ofCH375 USB chip, the program designing is also realized in this paper.
