Description: 8255A控制步进电机汇编程序
步进电机作为执行器件，广泛用于自动控制系统、印字位置的控制及XY记录仪的无关控制等各个领域，而步进电机最适宜于用微处理器来控制，此法应用于实验教学、科研中效果良好。
1、实现全数字化驱动电路
设计思路是采用步进脉冲分配器专用芯片PMM8713和程序计数器8253的方法。图1是采用可编程计数器8253、8255和PMM8713芯片的全数字控制方式接线图。在单片机系统中，只连接8253、8255和PMM8713各一个。

Description: 该题目要求使用LED16*16显示矩阵设计接口滚动显示汉字。使用8255把cpu与显示外设LED联系起来。16*16LED是16列阴极连在一起，16列阳极连在一起的256个二极管矩阵，当阳极为高电平，阴极为低电平时，二极管发光。通过8255的A口接前8列，高电平有效，C口接后8列，高电平有效，B口接前8行，低电平有效。-The subject requires the use of LED16* 16 show that the design interface matrix rolling display of Chinese characters. Using 8255 cpu and display peripherals LED link. 16* 16LED is linked to the cathode 16, anode 16 linked to the diode matrix 256, when the anode is high, the cathode is low, the light-emitting diodes. Of A through 8255 before I received eight, high effective, C after I received eight, high effective, B I take pre-8 line, active-low.
