標(biāo)題: 單片機(jī)按鍵控制步進(jìn)電機(jī)的程序修改
寫(xiě)了個(gè)按鍵控制步進(jìn)電機(jī)的程序，按鍵控制正反轉(zhuǎn)和停止，但是因?yàn)橛昧搜訒r(shí)導(dǎo)致按鍵不太好用，各位給看看要是用定時(shí)器實(shí)現(xiàn)，需要怎么改一下，或者有什么更好，更簡(jiǎn)潔的方法

單片機(jī)源程序如下:
#include "reg52.h"                      //此文件中定義了單片機(jī)的一些特殊功能寄存器
#define uchar unsigned char
#define uint unsigned int
sbit MOTOA = P1^0;       //定義A極
sbit MOTOB = P1^1;       //定義B極
sbit MOTOC = P1^2;       //定義C極
sbit MOTOD = P1^3;       //定義D極
sbit key1  = P0^0;
sbit key2  = P0^1;
sbit key3  = P0^2;
sbit key4  = P0^3;
void keyscan();
#define SPEED 400
void delay(uint i)       //延時(shí)函數(shù)
{
      while(i--);
}
void main()
{
      P1=0X00;
      while(1)
      {
      keyscan();
      }
}
void keyscan()
{
      if(key1==0)

            delay(10);
            if(key1==0)
