基于单片机的数字矩阵切换系统设计

The Design of Digital Matrix Switch System Based on MCU

通过对场逆程切换基本原理的分析,介绍了一种基于单片机的数字矩阵切换系统的设计方法;对系统硬件构成和软件设计作了详细的说明,所设计的矩阵系统具有记忆功能,能用键盘和PC机进行控制,用液晶模块显示系统的切换状态。该系统具有较高的性能价格比,已进入推广阶段。

In order to improving traditional matrix switch system function , this paper introduces a design method of matrix switch system based on MCU according to analyzing VBI （vertical blanking interval） switch basic principle. Hardware constitution and the design of software is explained in detail in the paper. The matrix system has memory function, can be controlled by keyboard and PC and displays the switch state by LCD. The system has relatively high cost effectiveness and is already in its phase of popularization.
