摘　　要：设计了一种具有自动切换和手动切换2种工作模式的视频矩阵切换器。利用ATmega16单片机作为主控芯片控制MT8816模拟开关矩阵,以控制输入信号和输出信号的选通,简单介绍了矩阵切换器的硬件电路设计和软件设计。The papper designed a video matrix switcher having automatic switching and manual switching two operation modes. It used ATmegal6 single chip computer as the main control chip to control MT8816 analog switch matrix so as to control the input signal and output signal of the gate. This paper briefly introduced the matrix switcher hardware circuit design and software design.
