使用python 3在树莓派2上运行pyfirmata时遇到问题

问题描述

我正在尝试在树莓派2上运行pyfirmata.我在这里安装了它:

I am trying to run pyfirmata on my raspberry pi 2. I have it installed in here:

/home/pi/pyFirmata

但是当我尝试运行以下代码时:

But when I try to run the following code:

from pyfirmata import Arduino, util
import time

board = pyfirmata.Arduino('/dev/ttyACM0')
analog_pin = board.get_pin('a:0:i')
it = pyfirmata.util.Iterator(board)
it.start()
analog_pin.enable_reporting()

while True:
    reading = analog_pin.read()
    if reading != None:
        voltage = reading * 5.0
        print("Reading= %f\t Voltage= %f" % (reading, voltage))
        time.sleep(1)

我收到以下错误消息:

Traceback (most recent call last):
  File "/home/pi/Arduino_Avoltage.py", line 1, in <module>
    from pyfirmata import Arduino, util
ImportError: No module named pyfirmata

我已经阅读了与pyfirmata一起安装的"read me"文件，而Arduino上已经安装了标准的firmata.我不知道我做错了什么.我需要将其与python 3配合使用，有什么建议吗?谢谢.

I have read the "read me" file that was installed with the pyfirmata and the Arduino has standard firmata installed on it. I can't figure out what I did wrong. I need this to work with python 3, any suggestions? Thanks.

推荐答案

您应将pyFirmata放入 site-packages :

You should put pyFirmata in site-packages:

/home/pi/Lib/site-packages/pyFirmata
