Abstract

The necessity of embedded RTOS used in embedded control system by analyzing application background of embedded RTOS has been explained.The characters of source code exoterically embedded RTOS μC/OS-Ⅱ and MCU C8051F020 has been briefly introduced,and the implementation of μC/OS-Ⅱ in the platform of C8051F020 has been expatiated importantly.Transplanted conditions and all modules of μC/OS-Ⅱ are put forward concretely,and in addition,key problems confronted in the implementation are discussed and relevant low-level hardware functions need to be programmed and analyzed in detail and indicative codes are given.On the basis of actual system requirements,the primary structure of stack is optimized and mended.
