Projet ESP

Projet sur une board esp32-8048S043. Le code suivant est fonctionnel. Il s'appuie sur le code officiel du github esp-idf.

• github esp-idf
• Lien du code

Il existe aussi une branch dev.

TODO

Status	Description
In Progress	Intégration le lvgl
In Progress	Intégration Marauder
In Progress	Lecture flux vidéo

Configurer vos accés wifi.

Tout se passe dans le fichier wifi_connect.h

Modifier les #define suivant:

• #define CONFIG_ESP_WIFI_SSID "YourSSID"
• #define CONFIG_ESP_WIFI_PASS "YourPASSWORD"

Build et Flash

Pour build et flasher le board, connectez la via usb et lancer la commande suivante:

idf.py -p PORT flash monitor

Pour sortir du mode monitor saissez les touches Ctrl-]

Un peu de doc car la doc ca fait du bien. :)
