Looking at this article: http://www.cnx-software.com/2015/09/26/status-of-orange-pi-boards-gpio-support/ it seems the GPIO pins can be accessed with File.WriteString() and (probably) File.ReadString() commands. It should be straight forward to write a B4A class or code module (I suggest the latter) that performs this functionality.
Hey guys , any news about Android @ Banana Pi ? How can we access GPIO under Android (Of course Linux + B4J can do this , but I need to do it with Android OS installed instead). Is there a B4J library/class available ?
