智能小车电机控制通常涉及Arduino或单片机平台,这里是一个简单的示例,使用Python模拟电机控制(如果你是在寻找硬件驱动的实际代码,那需要具体的硬件库,如PID或PWM控制):
```python
import RPi.GPIO as GPIO
# 定义GPIO引脚
motor_pin_left = 18
motor_pin_right = 23
# 设置GPIO模式为BCM
GPIO.setmode(GPIO.BCM)
def set_motors(left_speed, right_speed):
# 左右电机速度设置,范围通常是0-255或0-100%
GPIO.output(motor_pin_left, GPIO.HIGH if left_speed > 0 else GPIO.LOW)
GPIO.output(motor_pin_left, GPIO.HIGH if left_speed < 0 else GPIO.LOW)
GPIO.output(motor_pin_right, GPIO.HIGH if right_speed > 0 else GPIO.LOW)
GPIO.output(motor_pin_right, GPIO.HIGH if right_speed < 0 else GPIO.LOW)
pwm_left = GPIO.PWM(motor_pin_left, 50) # 50Hz PWM频率
pwm_right = GPIO.PWM(motor_pin_right, 50)
pwm_left.start(abs(left_speed))
pwm_right.start(abs(right_speed))
# 示例使用
set_motors(50, 0) # 向左前进
time.sleep(2) # 等待2秒
set_motors(0, 50) # 向右前进
GPIO.cleanup() # 关闭GPIO资源
