【Abstract】The paper introduces the transplantation of uC/OS-II to ARM at first. Basic on this, the hardware frame is designed according to the features of Ethernet Controller ENC28J60. Then it expatiates how to realize the transplantation of LwIP protol stack to the embedded RTOS(Real-Time Operating System) μC / OS-Ⅱ, and describes the software flow of ENC28J60 network card drive in detail, which makes uC/OS-II become a true RTOS with networking utilities.
