There are two buttons on the Photon:  

Il y a deux boutons sur le Photon:  

* the RESET button (when holding the Photon with its USB-port to the top, it's the button on the right)

* Le bouton RESET de réinitialisation (c'est le bouton de droite lorsque vous tenez le phitn avec le port USB vers le haut)

* the SETUP button (on the left).

* Le bouton SETUP de configuration (sur la gauche).

The RESET button will put the Photon in a hard reset, effectively rebooting the microcontroller. This is a good way to restart the application that you've downloaded onto the Photon.

Le bouton RESET permet de faire une réinitialisation matériel du Photon (''hard reset'' en anglais), ce qui redémarre/reboot le microcontrôleur. C'est une bonne façon de procéder au redémarrage d'une application que vous avez téléversé sur le Photon.

The SETUP button serves two functions after the Photon has booted:

Le bouton SETUP (configuration) est utilisé pour deux fonctions différentes {{underline|après le redémarrage/reboot}} du Photon:

* Hold down the SETUP button for three seconds to put the Photon into ''Soft-AP'' mode to connect it to your local Wi-Fi network. The LED should start flashing blue.

* Maintenez le bouton SETUP enfoncé pendant 3 secondes pour placer le photon en mode ''Soft-AP'' (point d'accès logiciel) pour le connecter sur votre réseau Wi-Fi. La LED devrait commencer à clignoter en bleu.

* Hold down the SETUP button for ten seconds to clear the Photon's memory of Wi-Fi networks.

* Maintenez le bouton SETUP enfoncé pendant 10 secondes pour effacer les réseaux WiFi enregistrés dans la mémoire du Photon.

The SETUP button serves four functions before the Photon has booted:

Le bouton SETUP à 4 autres fonctions {{underline|avant le redémarrage/Reboot}} du Photon:

* Hold down the SETUP button, tap on the RESET button and wait for '''less than 3 seconds''' to enter '''User Safe Mode''' mode, where the RGB LED will be flashing Magenta. Release the SETUP button. This is the most frequently mode, because your user application will not execute. This can be useful if you have a bug in your code that is keeping you from re-flashing it over the air, or causing other hanging issues.

* Hold down the SETUP button, tap on the RESET button and wait for '''less than 3 seconds''' to enter '''User Safe Mode''' mode, where the RGB LED will be flashing Magenta. Release the SETUP button. This is the most frequently mode, because your user application will not execute. This can be useful if you have a bug in your code that is keeping you from re-flashing it over the air, or causing other hanging issues.

* Hold down the SETUP button, tap on the RESET button and wait for '''3-6 seconds''' to enter '''Bootloader''' mode, where the RGB LED will be flashing Yellow. Release the SETUP button. In this mode you can reprogram the Photon over USB or JTAG. If you do this by accident, simply hit RESET button to leave Bootloader mode.
