This paper puts forward a scheme of intelligent instrument's embedded Ethernet access based on ARM,and expatiated on the hardware and software realization.Especially the μC/OS-Ⅱ real-time system and LwIP protocol stack transplanted to processor ARM and the key software of the LAN91C111 are given.The design realized by single chip processor and network card chip has low cost,high-speed performance and some other characters.It provides transparent data communication between intelligent instrument and distant terminal through Ethernet.
