我成功安装了armbian，WiringOP，可以访问gpio了。

如何从橙色 pi 零上的 nodejs 访问 gpio？

这是gpio输出：

hygy@orangepizero:~/WiringOP/gpio$ sudo ./gpio readall
[sudo] password for hygy:

您可以使用标准流。

例如，如果您使用 Python 访问 GPIO，则可以将该 Python 进程的标准输出重定向到您的 Node.js 应用程序。

我发现这个很好的教程解释了如何做到这一点：http: //www.sohamkamani.com/blog/2015/08/21/python-nodejs-comm/
