Ceci est une question webiopi

Je souhaite utiliser webiopi pour afficher plusieurs boutons sur le navigateur et activer / désactiver plusieurs GPIO pour la tarte aux framboises, mais cela ne fonctionne pas. Plus précisément, je voudrais activer et désactiver GPIO12 et 13 avec les boutons du navigateur, respectivement. Lorsque je crée un programme comme indiqué ci-dessous, le navigateur affiche «Ce site n'est pas accessible». Si vous supprimez la 7ème ligne "LIGHT2 = 13", la 14ème ligne "GPIO.setFunction (LIGHT2, GPIO.OUT)" et la dernière ligne "GPIO.digitalWrite (LIGHT2, GPIO.LOW)" de script.py, le navigateur accédera. Vous ne pouvez utiliser que GPIO12. Comment puis-je rendre GPIO13 opérationnel également? Je vous remercie.
