摘要
二维条码技术正在渗透到社会的各个领域,快速精准的二维条码识别器具有很好的应用前景。以TI公司的TMS320VC5416 DSP芯片为核心,采用COMS图像传感器采集二维条码数据,用CPLD实现系统整体的逻辑控制,实现了一种带有USB接口的便携式二维条码识别器的设计。识别器本身可以存储一定容量的数据,也可通过USB 2.0接口同PC连接共享数据。
Since 2-dimensional barcode has been used in many domains,the fast and precise 2-dimensional barcode identifi er has a bright future. Based on TI＇s TMS320VC5416 DSP chip, a portable 2-dimensional barcode identifier with USB interface is designed, which uses COMS image sensor to gather 2-dimensional barcode data and adopts CPLD to realize the logic control of the whole system. The identifier can store a certain capacity of data, and share data with PC via USB 2.0 interface.
