电机驱动电路和程序,大家帮忙

第一次做电机驱动,出了很多状况,请大家帮忙啊!!!<br />我在P2.0~P2.7上接了发光二极管!在没接步进电机的时候,发光管正常点亮,熄灭!在接上步进电机后,发光管就停在一个状态了~~~(P2.2,P2.3,P2.6,P2.7亮,其他灭),当用电表去测OUTA,OUTB的电压的时候,二级管会闪,但停停闪闪的....<br />电机也是停停,动动~~~~正转反转....郁闷<br />下面是程序:<br />/*************************************************<br /><br />步进电机驱动<br /><br /><br />*************************************************/<br /><br />#include&nbsp;&ltREG54.H&gt<br />#include&nbsp;&ltintrins.h&gt<br />#define&nbsp;uchar&nbsp;unsigned&nbsp;char<br /><br />#define&nbsp;uint&nbsp;unsigned&nbsp;int<br /><br />&nbsp;<br />code&nbsp;unsigned&nbsp;char&nbsp;seg7code[32]={0xcc,0xbd,0xae,0x9f,0x8f,0x1f,0x2e,0x3d,<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0x4c,0x5b,0x6a,0x79,0x78,0x71,0x62,0x53,<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0x44,0x35,0x26,0x17,0x87,0x97,0xa6,0xb5,<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0xc4,0xd3,0xe2,0xf1,0xf8,0xf9,0xea,0xdb};<br />/*延时程序<br /><br />由Delay参数确定延迟时间<br /><br />*/<br /><br />void&nbsp;mDelay(unsigned&nbsp;int&nbsp;Delay)&nbsp;<br /><br />{&nbsp;unsigned&nbsp;int&nbsp;i;<br /><br />for(;Delay&gt0;Delay--)<br /><br />{&nbsp;for(i=0;i&lt124;i++)<br /><br />{;}<br /><br />}<br /><br />}<br /><br /><br /><br />void&nbsp;main()<br /><br />{<br />unsigned&nbsp;char&nbsp;j;<br />for(;;)<br /><br />{&nbsp;<br />for(j=0;j&lt31;j++)<br />{<br />mDelay(200);<br />P2=seg7code[j];<br />}<br /><br />}<br /><br />}<br />

这个是自己做&nbsp;的电路

为了看单片机有没正常工作,我在P2.0~P2.7接了8个二极管,不知道对电平有没影响

步进电机是几相的，有几条出线？

麻烦

二极管干扰了~~~`
