树莓派5运行超声波传感器Python代码遇RuntimeError问题求助

树莓派5运行超声波传感器Python代码报错:RuntimeError: Cannot determine SOC peripheral base address

我在树莓派5上运行Python代码测试超声波传感器,代码如下:

import RPi.GPIO as GPIO
import time
 
#GPIO Mode (BOARD / BCM)
GPIO.setmode(GPIO.BCM)
 
#set GPIO Pins
GPIO_TRIGGER = 5
GPIO_ECHO = 6
 
#set GPIO direction (IN / OUT)
GPIO.setup(GPIO_TRIGGER, GPIO.OUT)
GPIO.setup(GPIO_ECHO, GPIO.IN)
 
def distance():
    # set Trigger to HIGH
    GPIO.output(GPIO_TRIGGER, True)
 
    # set Trigger after 0.01ms to LOW
    time.sleep(0.00001)
    GPIO.output(GPIO_TRIGGER, False)
 
    StartTime = time.time()
    StopTime = time.time()
 
    # save StartTime
    while GPIO.input(GPIO_ECHO) == 0:
        StartTime = time.time()
 
    # save time of arrival
    while GPIO.input(GPIO_ECHO) == 1:
        StopTime = time.time()
 
    # time difference between start and arrival
    TimeElapsed = StopTime - StartTime
    # multiply with the sonic speed (34300 cm/s)
    # and divide by 2, because there and back
    distance = (TimeElapsed * 34300) / 2
 
    return distance
 
if __name__ == '__main__':
    try:
        while True:
            dist = distance()
            print ("Measured Distance = %.1f cm" % dist)
            time.sleep(1)
 
        # Reset by pressing CTRL + C
    except KeyboardInterrupt:
        print("Measurement stopped by User")
        GPIO.cleanup()

已尝试以下操作,但始终出现RuntimeError: Cannot determine SOC peripheral base address错误:

  • 以root身份通过sudo运行代码
  • 重装RPi.GPIO库
  • 在树莓派配置中启用GPIO接口
  • 执行系统更新命令:
    sudo rpi-update
    sudo reboot
    sudo apt-get update
    sudo apt-get upgrade
    sudo adduser pi gpio
    
  • 更新pip和setuptools至最新版本:
    pip install --upgrade pip setuptools
    
  • 从源码安装python-gpiozero:
    git clone https://github.com/RPi-Distro/python-gpiozero.git
    cd python-gpiozero
    sudo python setup.py install
    

请求解决该问题。
