在 Raspberry Pi 上使用 RPi.GPIO 设置时获取 "Segmentation Fault" 2

Question

我在使用 gpio.setup(pin, GPIO.OUT)

时遇到错误

我目前正在使用 Ubuntu Mate For Raspberry Pi 2 并使用 Python 2.7 和 python-rpi.gpio 0.5.10.1 模块。

当我尝试输入 GPIO.setup(pin, GPIO.OUT) 时抛出 SegmentationFault。

编辑：这是我一直在处理的代码

GPIO.cleanup()

我不知道这个问题，我认为这是 python-rpi.gpio 模块相关的，因为我对 Raspbian 和 python 没有任何问题-rpi.gpio 预装。

Answer 1

我有同样的症状，Raspberry Pi 2 与 Ubuntu Mate，0.5.11 模块。我的代码更简单：

import time
import RPi.GPIO as GPIO
print "before GPIO.setmode"
GPIO.setmode(GPIO.BOARD)
print "before GPIO.setup"
GPIO.setup(11, GPIO.IN)
print "after GPIO.setup"

它在 GPIO.setup 期间出现段错误。我会尝试切换回 Raspbian，看看是否可行。如果是这样，也许可以从那里的源代码卸载并重新安装 RPi.GPIO。
