以下是一个简单的51单片机利用四路红外循迹模块循双黑线的代码示例:
```c
#include <reg51.h>
sbit LeftSensor1 = P1^0; // 左传感器1
sbit LeftSensor2 = P1^1; // 左传感器2
sbit RightSensor1 = P1^2; // 右传感器1
sbit RightSensor2 = P1^3; // 右传感器2
sbit LeftMotorA = P2^0; // 左电机正转
sbit LeftMotorB = P2^1; // 左电机反转
sbit RightMotorA = P2^2; // 右电机正转
sbit RightMotorB = P2^3; // 右电机反转
void Delay(unsigned int time) {
unsigned int i, j;
for (i = 0; i < time; i++) {
for (j = 0; j < 1000; j++) {
}
}
}
void Stop() {
LeftMotorA = 0;
LeftMotorB = 0;
RightMotorA = 0;
RightMotorB = 0;
}
void Forward() {
LeftMotorA = 1;
LeftMotorB = 0;
RightMotorA = 1;
RightMotorB = 0;
}
void Left() {
LeftMotorA = 0;
LeftMotorB = 0;
RightMotorA = 1;
RightMotorB = 0;
}
void Right() {
LeftMotorA = 1;
LeftMotorB = 0;
RightMotorA = 0;
RightMotorB = 0;
}
void main() {
while (1) {
if (LeftSensor1 == 1 && LeftSensor2 == 0 && RightSensor1 == 0 && RightSensor2 == 1) {
Forward();
} else if (LeftSensor1 == 0 && LeftSensor2 == 1 && RightSensor1 == 1 && RightSensor2 == 0) {
Forward();
} else if (LeftSensor1 == 0 && LeftSensor2 == 1 && RightSensor1 == 0 && RightSensor2 == 1) {
Left();
} else if (LeftSensor1 == 1 && LeftSensor2 == 0 && RightSensor1 == 1 && RightSensor2 == 0) {
Right();
} else {
Stop();
}
}
}
```
这段代码假设你的四路红外循迹模块的输出引脚分别连接到了P1口的0-3号引脚,电机的控制引脚分别连接到了P2口的0-3号引脚。代码中的`Forward()`函数用于使车向前行驶,`Left()`函数用于使车向左转,`Right()`函数用于使车向右转,`Stop()`函数用于停止车辆。在`main()`函数中,根据红外传感器的状态来控制车辆的动作。具体的判断逻辑可以根据你的具体传感器布局来进行调整。
