Un esempio viene riportato al Wiki di Google Code ...peccato che sia sbagliato
Dopo un po' di ricerche ecco una pagina funzionante che accende e spenge il solo pin GPIO 25. L'aspetto fondamentale e' che prima di usare il pin questo deve essere dichiarato come output
Il file deve essere posizionato in /usr/share/webiopi/htdocs
