摘要
介绍了一种基于AT89S52单片机所构成的大容量存储测试系统的设计。该测试系统采用CH375芯片作为USB主控芯片,使用普通U盘为存储设备用以存储MTX传感器采集到的大量多参数数据,配备相应的软件实现数据的再现,方便与计算机的数据交换,并给出了相应硬件电路以及软件的设计。最后,给出了设计调试结果,证明系统设计方案的可行性。
A kind of design for mass-storage testing system based on the composition of AT89S52 microcontroller is represented.The testing system takes CH375 chip as USB host chip,and uses common U disk as storage device for storing a large number of multi-parameter data collected with MTX sensor and equipped with corresponding software for data reappearance which facilitates data exchange of computer.Corresponding hardware circuit and design of software are introduced.At last,the debugging result is presented and the feasibility of system is certified.
