A Design And Implement Of Data Acquisition And Storage System With Embedded UC/OS-Ⅱ Technique

A design and implement of Data Acquisition and Storage System with embeddedμC/OS-Ⅱtechnique is provided in this paper,based on the analysis of embeddedμC/OS-Ⅱsystem and the basic technology behind USB.With USB bus development,make use of interface technology extend embedded system,We design an embedded and Data Acquisition system that can acquisition data and store to the USB at the non-PC environment.It can satisty the application of some special situations,with higher pratctical value.The topic designs the Data Acquisition system according to ARM (S3C44BOX)and USB host chip(AT43USB370),with embeddedμC/OS-ⅡData Acquisition system.The main contents includes the real-time embeddedμC/OS-Ⅱoperating system,USB interface circuit,A/D converter etc.In realization,it is divided into A/D converter module,Keyboard module, the LCD display and USB host interface module,task and application softwares.We completed the design of hardware and software about interface function,driver function,mission and applies procedure and document system etc.This Paper describes the basic technology of USB and embeddedμC/OS-Ⅱoperating system,then mainly includes hardware and software.It covers the following fields,the last of this paper describes debugging and analysis the system.
