| Abstract: | This paper describes a new design of two-dimensional bar codes data acquisition,which adopts Intel XScale PXA255 as hardware plat and embedded operation system WinCE as software plat,and may carry on the decoding of two-dimensional bar code information effectively.The application is divided into multi-task,which simplifies the software design of application system.The primitive picture of two-dimensional bar codes is gained by use of the CMOS numeral picture sensor chip,again the image data is carried on pr... |
