使用51控制带AB相编码器电机

存51定时器代码，需要自提

实验题目，懂的都懂

上电时显示提示符。按 A 键再按 B 键后， 显示两键按下之间的时间 t（t

#include <reg52.h>sbit led1=P1^0;sbit led2=P1^1;sbit led3=P1^2;int flag=1;unsigned int timer,timer0=0;void time0_init(){ TMOD = 0x01; TL0 = 0x00; TH0 = 0x4c; //50ms ET0=1; TR0=1; EA=1; }void main(){ time0_init.

#include <reg52.h>sbit pwm=P2^0;unsigned int timer = 0;void main(void){ TMOD = 0x01; TL0 = 0x48; TH0 = 0xff; //200us ET0=1; TR0=1; //开定时器0 EA=1; //开总中断 while(1);}void time0() interrupt 1{ TL0 = 0x48; TH0 = 0x.

内容：每次按下K1时递增点亮--只LED，全亮时再次按下则再次循环开始，K2按下后点亮上面4只LED，K3按下后点按键原理图：LED原理图：代码如下：#include <reg52.h>typedef unsigned int u16; typedef unsigned char u8;sbit k1=P3^1;sbit k2=P3^0;sbit k3=P3^2;sbit k4=P3^3;#define k1_PRESS 1#define k2..

#include <reg52.h> #include <intrins.h>#include <stdio.h> #define uchar unsigned char#define uint unsigned int sbit TRIG = P1^2; sbit ECH0 = P1^3; uint time=0;float Distance=0;bit flag =0; void Timeinit(){.

#include <reg52.h>#include <stdio.h>//printf函数库 #define uint unsigned int#define uchar unsigned charvoid UsartInit(){ TMOD=0X20;//方式2 TH1=0XFD;//9600 TL1=0XFD; TR1=1;//开启T1 REN=1;//允许串口接收 SM0=0; SM1=1; EA=1;//总中断 ES=1;//串口中断}.

可以使用CV大法哦^_^
