【Abstract】 Combining with the application of video supervision system implemented with embedded real-hme operating system VxWorks,with the serial communication in it as an example, the key techniques and corresponding mechanism about realization of device operating and data communication in VxWorks are discussed. Software diagram and corresponding program examples are provided. The communication mechanism discussed here can expand to other communication devices beside serial device in VxWorks.更多还原
