[Development of a multi-parameter and low-power monitor].

The development of a multi-parameter and low-power monitor is discussed in this paper. The monitor equips an AT91SAM9261 microprocessor as its main controller and contains multi-parameter signal collecting module, data storage module, human-computer interaction module, online communications module and printing module. The whole software system is based on the uC/OS-II equipped by uC/GUI, which is used to facilitate interface design. At the same time, for the convenience of data management, a YAFFS2 file system is transplanted. The monitor has the advantages of low consuming, low cost, real-time control and multi-functions.
