摘要
为实现单片机控制系统与其他设备或系统的数据共享 ,设计了单片机与软盘驱动器的接口。解决了系统存储器扩展、DMA通道设计等硬件问题。结合工作原理介绍指出了软件的设计要点。该接口设计几乎不占用单片机有限的端口资源。
In order to exchange data between a single-chip microcomputer control system and other device or system, the interface between single-chip microcomputer and a floppy disk driver has been designed. The hardware circuit has been constructed. It includes: extending the memory space of single-chip microcomputer control system, setting up a DMA channel, and so on. The key design of software has been given in the course of explaining interface's principle. This interface has hardly taken up limited port resource of single-chip microcomputer.
