μC/OS-II在TQS3C2440上的扩展

his paper is about and the implementation ofμC/OS-II expansion on TQS3C2440. μC/OS-II is an embedded real-time operating system. It belongs to deprive the kernel.User can switch between tasks and task scheduling in real time. With its light-weight and transplantation convenience, It is widely used in the small and high demand of real-time embedded systems . μC/OS-II has task scheduling, time management and other functions.And it can realize the communication between tasks and interrupts by call kernel function. However,it does not have file management, network capabilities and other content like other operating system eg. linux . So if you need to use these function, you need to expand μC/OS-II . In this paper, by transplanting LWIP network protcol on the μC/OS-II to achieve network function, by transplanting fatfs to achieve document management capabilities, coupled with the realization of the keyboard and display, the μC/OS-II RTOS is extended to be a complete operating system.
