摘要
设计了一个可以满足大多数的芯片测试工作的包含8255、8253的通用型I/O接口卡。其可以利用微型机的显示器作为测试系统的显示系统,并具有C语言强大的浮点数的运算能力,测试方便,从而可减少开发周期,节省开发成本。
We need to select the chip and test it' s capability during circuit develepment. A universal I/O interface card including 8255,8253 can satisfy most work in which chip be tested and then can use the microcomputer's monitor as vidio system of our work and have float operation capability of powerful C program language, at the same time we can decrease the circle of development and the cost of our work.
