If I might suggest - wiringPI only works for the PI - whereas WiringOP works for the likes of OrangePI - it does need some customisation for the likes of the FriendlyArm units and currently the pin numbers are wrong on all but the OrangePi - modifying with a parameter to set up what hardware is in use would make this INCREDIBLY useful as it has the GPIO tool which can be used by a non-root user - and hence by Node-Red EXEC node. I am running a NEO right now and I have a led flashing on and off using this - I cannot however figure out how to get the I2c running - I suspect something is missing. Not everyone wants to build music centres and so access to hardware as easy as it is on the real Pi would be a godsend.
