Isolating embedded system has not been adapted to current development tendency. More and more embedded
systems need networking for communicating with each other. µC/OS-II, which is a typical embedded real
time operating system and contains a kernel without network protocol, has been widely used in a large number of
embedded systems. So it is of significance to join network protocol into µC/OS-II. In this paper, a networking method
is proposed to embedded equipments based on µC/OS-II. LPC2200 based on ARM7TDMI-S is used as the core of
hardware platform, µC/OS-II embedded real-time operating system and LwIP (Light Weight IP) are used as software
platform, ADS1.2 as compiler. Through the realization of files that are related to the processor LPC2200, the porting
of µC/OS-II into ARM7 is implemented. Through the realization of the LwIP operating system emulation layer and
realization network chip RTL8019AS driver, the porting of LwIP into µC/OS-II is implemented. On these foundations,
a remote monitoring application is successfully developed. Experiment results show that proposed approach can
be successfully used for embedded equipments networking control.
