本項目是基于8086的點陣顯示，可以通過按鍵顯示所要顯示的內容
仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）

單片機源程序如下:

IOY0 EQU 0C400H ;片選第一片8255的地址
IOY1 EQU 0C440H ;片選第二片8255的地址
O8255_A EQU IOY0+00*2 ;第一片8255的地址的A口
O8255_B EQU IOY0+01*2 ;第一片8255的地址的B口
O8255_C EQU IOY0+10*2 ;第一片8255的地址的C口
O8255_MODE EQU IOY0+11*2 ;第一片8255的地址的控制字寄存器
T8255_A EQU IOY1+00*2 ;第二片8255的地址的A口
T8255_B EQU IOY1+01*2 ;第二片8255的地址的B口
T8255_C EQU IOY1+10*2 ;第二片8255的地址的C口
T8255_MODE EQU IOY1+11*2 ;第二片8255的地址的控制字寄存器
