Question

我在使用gpio.setup(pin, GPIO.OUT)

时收到错误消息

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

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

编辑：这是我一直在努力的代码

GPIO.cleanup()

我不知道这个问题，我认为这是python-rpi.gpio模块相关的，因为我没有预先安装python-rpi.gpio的Raspbian有任何问题。

Answer 1

我有相同的症状，Raspberry Pi 2和Ubuntu Mate，0.5.11模块。我的代码更简单：

char[]

在GPIO.setup期间出现段错误。我会尝试切换回Raspbian，看看是否有效。如果是这样，也许可以从源代码卸载并重新安装RPi.GPIO。
