C语言程序源代码

1、C语言程序源代码#include<REGX51.H>/51寄存器定义#include"intrins.h"#definecontrolP1/P1_0:A相，P1_1:B相，P1_2:C相,P1_3:D相#definediscodeP0/显示代码控制端口#defineucharunsignedchar定义无符号型变量#defineuintunsignedintsbiten_dm=P3A0;显示代码锁存控制sbiten_wk=P3A1；位控锁存控制ucharcodecorotation4=(0x03,0x06,0x0c,0x09;/电机正转ucharcoderoll

5、读取码值的关键，如果来的脉冲不管是高电平还是低电平，靠左移一位保存脉冲的状态值.elsereturn0;key_val()按键处理函数这里是读取将存好的码值进行处理.看是什么代码无(ucharkey;key=keyscan();这里是读取码值并存放在key里switch(key)/这里是比照读取的码值(case0xee:/按键7'读取的码值=0xEE，则是按键“确代码/while(P2=0xee);setstep=setstep*10+7;/步伐数这里是输入”setstep+7步伐数比照读取的码值，/setstep原来可能是有数字的。step=setstep;butcount+;计数，

6、看输入拉几个数字if(butcount>=5)输入的数字超过5个就置0，无效(butcount=0;setstep=0;break;case0xde:按键8读版的码值=0xdE，则是按键“明代码其他同”7”/while(P2=0xde);setstep=setstep*10+8;butcount+;step=setstep;if(butcount>=5)(butcount=0;setstep=0;break;case0xbe:/按键9同上”7”/while(P2=0xbe);setstep=setstep*10+9;butcount+;step=setstep;if(butcoun
