Coral Dev Board Mini环境传感器板GPIO问题

Question

我使用环境传感器板与我的谷歌珊瑚开发板Mini。所有直接在板上的GPIO调用都会导致相同的错误，在这个例子中

from periphery import GPIO
gpio = GPIO(138, "low")
OSError: [Errno 22] Invalid argument
periphery.gpio.GPIOError: [Errno 22] Exporting GPIO: Invalid argument

细节:

我有同样的问题与谷歌enviro_demo.py:enviro = EnviroBoard()同样的错误。

任何想法?所有已经从头开始安装/flash:)就在几分钟前。谢谢你。

最好的,弗兰克。

对于所有人，我从Coral支持那里得到了这个答案:

"[…我和这里的团队讨论了一下，发现开发板mini和环境板目前还不能一起工作。

我们不知道何时支持这个组合。
