Grafting of μCOSⅡ on the Cortex-M3 Based ARM Processor

Guan Hai,Feng Dazheng(School of Electronic Engineering,Xidian University,Xi'an 710071,China)  
This paper introduces the process of grafting an open source real time operating system μCOSII on the ARM processor STM32F103VBT6.Several basic concepts of the Cortex-M3 are briefly introduced,on the basis of which all of the source code files necessary to modify are modified by use of the C language or assembly language with detailed explanations given.A simple example of the application based on μCOSII is also given.The differences between the method of developing applications based on an embedded operating system and the traditional method are discussed with the former shown to be a better method.The grafting process is proved to be successful.
