好的,以下是基于树莓派4B的轮式智能车电机驱动代码,使用TB6612电机驱动和八路灰度传感器:
```python
import RPi.GPIO as GPIO
import time
# 定义TB6612电机驱动的引脚
AIN1 = 17
AIN2 = 18
BIN1 = 22
BIN2 = 23
PWMA = 12
PWMB = 13
# 定义八路灰度传感器的引脚
sensor_pin = [6, 13, 19, 26, 12, 16, 20, 21]
# 初始化GPIO
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
# 初始化TB6612电机驱动的引脚
GPIO.setup(AIN1, GPIO.OUT)
GPIO.setup(AIN2, GPIO.OUT)
GPIO.setup(BIN1, GPIO.OUT)
GPIO.setup(BIN2, GPIO.OUT)
GPIO.setup(PWMA, GPIO.OUT)
GPIO.setup(PWMB, GPIO.OUT)
# 初始化八路灰度传感器的引脚
for pin in sensor_pin:
GPIO.setup(pin, GPIO.IN)
# 定义电机控制函数
def motor_control(motor, speed):
if motor == 'A':
if speed >= 0:
GPIO.output(AIN1, GPIO.LOW)
GPIO.output(AIN2, GPIO.HIGH)
else:
GPIO.output(AIN1, GPIO.HIGH)
GPIO.output(AIN2, GPIO.LOW)
PWM = GPIO.PWM(PWMA, 500)
PWM.start(abs(speed))
elif motor == 'B':
if speed >= 0:
GPIO.output(BIN1, GPIO.LOW)
GPIO.output(BIN2, GPIO.HIGH)
else:
GPIO.output(BIN1, GPIO.HIGH)
GPIO.output(BIN2, GPIO.LOW)
PWM = GPIO.PWM(PWMB, 500)
PWM.start(abs(speed))
# 定义灰度传感器读取函数
def read_sensor():
sensor_value = []
for pin in sensor_pin:
if GPIO.input(pin) == GPIO.HIGH:
sensor_value.append(0)
else:
sensor_value.append(1)
return sensor_value
# 主函数
if __name__ == '__main__':
try:
while True:
# 读取灰度传感器的值
sensor_value = read_sensor()
print(sensor_value)
# 控制电机的运动方向和速度
motor_control('A', 50)
motor_control('B', 50)
# 延时一段时间
time.sleep(0.1)
except KeyboardInterrupt:
GPIO.cleanup()
```
这段代码可以实现基于树莓派4B的轮式智能车电机驱动功能,并且使用了TB6612电机驱动和八路灰度传感器。其中,motor_control函数用于控制电机的运动方向和速度,read_sensor函数用于读取灰度传感器的值,主函数中则通过读取灰度传感器的值来实现车的自动循迹。
