Abstract
Porting Embedded RTOS into MCU would be a hot topic of the development of embedded system at present and in the future. The paper introduces the advantages of Embedded RTOS in MCU application and the characteristic of
μC/OS-Ⅱ.It analyses the porting process and the basic method ofμC/OS-Ⅱ,combing the application of data collection and LCD display with AVR(ATmega128). This system could shortcut the design process and suit the real-time request to inhance the reliability of system. After the operated system is disposed in reasonable way and the priority set before hand with be transplanted and edit then the precedure and the operated system would be loaded into MCU. The analog voltage signal gathered in real-time will be shown on LCD, which is a function of the design realized through the periphery circuit with AVR(MCU).
