Coral Dev Board Mini存在环境传感器板GPIO问题

Question

我将环境传感器板与我的Google Coral Dev Board Mini一起使用。 在本例中，所有类型的GPIO调用直接在电路板上导致相同的错误

from periphery import GPIO
gpio = GPIO(138, "low")

OSError: [Errno 22] Invalid argument
periphery.gpio.GPIOError: [Errno 22] Exporting GPIO: Invalid argument

我对Google enviro_demo.py也有同样的问题： enviro = EnviroBoard() 同样的错误

有什么想法吗？所有这些都是在几分钟前从零开始安装的。 多谢各位

最好的， 坦率的

总之，我从Coral support得到了这个答案：

“[…]我在这里与团队进行了讨论，并了解到开发板mini和Enviro板目前无法协同工作

我们没有关于何时支持这种组合的时间表

感谢Coral支持团队[…]”
