ZF2N1L5U9I6文档编码:CX8E2V10R10M10 HF7J8B2D6Y9 ZF2N1L5U9I6学习文档仅供参考仿真部分由Protues实现。Protues 可以嵌入单片机的二进制代码，便于程序调试。本次仿真的电路图如下所示：其中，按键为输入电路，为行列式设计，行线接入8255 芯片的 PC0 口，列线分别对应接入 8255 芯片的 PB0PB3 口，与数码管的位选线共享端口。数码管为输出电路。本次实验一共要使用6 个数码管，以动态显示方式轮番输出字符，6 个数码管的段码线相互并联后接入8255 芯片的 PA 端口，a、b、c、d、e、f、g 端口分别连接 PA0PA6 端口，在8255 芯片引脚和段码线之间分别一一串联7406 芯片、并联一个排阻以提供激励，使数码管发亮。位选线则以数码管的接地线组成，从时十位、时个位、分十位、分个位、秒十位、秒个位分别接入8255 芯片的 PB0PB5 端口，其中PB0PB3 这四个端口分别并联上四个按键。同理，每个引脚和8255 芯片之间都一一串联上7406 芯片和并联上排阻。位选线负责选取某一时间片要显示哪一个数码管，显示间隔由源程序决定。五、焊接本次实验由于没有提供8051 芯片、8255 芯片。上述芯片均由伟福实验箱提供，焊接的时候需要在万用板上面预留PA、PB 接线口。另外，万用板上面同时需要预留电源的正负极、PC0 口接线，共计17 个接线口。由于万用板的大小的限制及芯片引脚定义的影响，实际上的电路图不会和仿真软件的电路图完全一致，不过大体上还是一样的。还有，本次焊接实际上需要比较多的电线，尤其是数码管部分，由于相邻引脚非常贴近，在焊接的时候要非常留心，谨防相邻两点短路。在焊接完成后，由于背板上面线路众多，需要用胶纸固定整理，防止导线脱落。焊接完成后，万用板上面已经有相应的接线，于是进行硬件实现部分。文档编码:CX8E2V10R10M10
