一：最简单的51开发板电机驱动小车实物接线图

1.电机模块开发

1.1接线图

L9110s是一种双路直流电机驱动芯片，常用于控制小型电机的转动。它有多种封装形式，如DIP、SOP等，可以方便地与其他电路连接。L9110具有低电压、低电流和高效率等特点，能够提供稳定的电机驱动电流，同时还具有过热保护功能，能有效地保护电机和芯片本身。由于其成本低廉、易于使用，因此在智能小车、机器人、飞行器等各种电子设备中广泛应用。

单片机只连接P3^3,的线 和P3-4+5+6的线（输入法问题），电机驱动芯片的电源由电池驱动

1.2实物图

1.3电机模块

二：电机模块开发代码

2.1代码界面预览（代码封装）

2.2主函数main.c

#include<reg52.h>
#include<delay.h>

//声明
	goForward();
	goBack();

void main(){
	goForward();
	Delay1500ms();            
	goBack();
	Delay1500ms();
}

2.3电机motor.c

#include<reg52.h>//要用sbit,就要用到reg52.h
sbit RightCon1A =P3^2;
sbit RightCon1B = P3^3;

sbit LeftCon1A = P3^4;
sbit LeftCon1B = P3^5;

void goForward(){
	LeftCon1A = 0;//是0还是1，得看datasheet,现场也可以自己调试出来
	LeftCon1B = 1;
	
	RightCon1A = 0;
	RightCon1B = 1;
}
void goBack(){
	LeftCon1A = 1;
	LeftCon1B = 0;
	
	RightCon1A = 1;
	RightCon1B = 0;
}

2.4延时函数 delay.c

//用stc烧录软件自动生成

#include<intrins.h>

void Delay1500ms()		//@11.0592MHz
{
	unsigned char i, j, k;

	_nop_();
	i = 11;
	j = 130;
	k = 111;
	do
	{
		do
		{
			while (--k);
		} while (--j);
	} while (--i);
}

2.5延时头文件

void Delay1500ms();

2.6 52头文件

（这部分代码可以忽略，一般不需要改，只要在main.c头文件引用了#include<reg52.h> ）
