摘要
介绍了采用ARM7和uClinux嵌入操作系统实现LED屏脱机控制卡的设计方案,该方案可实现与PC机进行10/100 MB以太网和普通串口2种方式的通信.软件采用多任务的编程方法来提高运行速度,描述了网络驱动及网络通信的实现.软硬件的初步调试验证了方案的可行性,比传统的采用8位或16位微处理器的脱机卡在运算速度、存储空间、图像显示效果等方面有很大提高.
The scheme of off-line control card for LED screen display using ARM7 and uClinux embedded operating system was presented. It can realize two kinds of communication with PC： 10M/100M Ethernet and UART. To improve the speed of execution, multiple-task programming was used in software design. Network driver and communication were particularly discussed. The debugging of software and hardware shows that the scheme is feasible,and its operational speed, storage capacity, and the effect of image display etc. are highly improved compared with the traditional off-line card using 8/16 bits microcomputer.
