使用python使用BBB读取多个超声波传感器

import Adafruit_BBIO.GPIO as GPIO
import time

# 定义超声波传感器的Trig和Echo引脚
sensors = [
    {'trig': 'P8_10', 'echo': 'P8_12'},
    {'trig': 'P8_14', 'echo': 'P8_16'}
]

# 初始化GPIO引脚
for sensor in sensors:
    GPIO.setup(sensor['trig'], GPIO.OUT)
    GPIO.setup(sensor['echo'], GPIO.IN)

# 读取超声波传感器数据
def read_distance(sensor):
    # 触发超声波信号
    GPIO.output(sensor['trig'], GPIO.HIGH)
    time.sleep(0.00001)
    GPIO.output(sensor['trig'], GPIO.LOW)

    # 等待超声波信号返回
    while GPIO.input(sensor['echo']) == 0:
        pulse_start = time.time()

    while GPIO.input(sensor['echo']) == 1:
        pulse_end = time.time()

    # 计算距离
    pulse_duration = pulse_end - pulse_start
    distance = pulse_duration * 17150
    distance = round(distance, 2)

    return distance

# 读取所有超声波传感器的数据
def read_all_distances():
    distances = []
    for sensor in sensors:
        distance = read_distance(sensor)
        distances.append(distance)
    return distances

# 测试代码
while True:
    distances = read_all_distances()
    print(distances)
    time.sleep(1)
