The paper researches the kernel of Real-Time Operating System μC/OS-Ⅱ and the method of porting it to PIC18F8720 which is the PIC18 series MCU of Microchip Corporation. It solves the four key functions and presents the most important and difficult problems in the course of porting μC/OS-Ⅱ. The porting method is catholicized and can be used to other series MCU. A porting has been implemented on board, and the system runs steadily and reliably under multitask environment. By testing, the real time parameters have reached the demand of designing. So the paper has common guidance in porting operating system to other series MCU.
