想用用Pico连接pca 9685,代码如下: from machine import I2C,Pin #正常 import time #正常 from servo import Servos #正常 i2c=I2C(0,sda=Pin(0), scl=Pin(1), freq=10000) #正常 s=Servos(i2c,address=0x40) #报错!! 运行最后一句时就会报错,看别人的教程都是这样做的,但我这就出错,求帮助。 报错如下: Traceback (most recent call last): File "stdin", line 5, in <module> File "servo.py", line 13, in __init__ File "pca9685.py", line 9, in __init__ File "pca9685.py", line 18, in reset File "pca9685.py", line 12, in _write OSError: [Errno 5] EIO
