-# ESP32 radio
+# ESP32 Radio
+
+Radio internet WiFi basée sur ESP32 avec interface web intégrée et contrôles physiques.
+
+## 🎵 Pour l'utilisateur
+
+### Première utilisation
+
+1. **Alimentez la radio** : Au premier démarrage, la radio entre automatiquement en mode configuration
+2. **Connectez-vous au WiFi** : Réseau `ESP32_Radio_Config` (mot de passe: `radio12345`)
+3. **Configurez votre WiFi** : Allez sur http://192.168.4.1 et entrez vos paramètres WiFi
+4. **Redémarrage automatique** : La radio se connecte à votre réseau et est prête
+
+### Utilisation quotidienne
+
+#### Contrôles physiques
+
+- **🔘 Appui court** : Mise en veille (économie d'énergie)
+- **🔘 Appui long (2s)** : Mode sélection de stations (LED clignote 3x)
+- **🔘 Appui très long (5s)** : Reset WiFi et retour en mode configuration
+- **🎛️ Potentiomètre** :
+  - Mode normal : Contrôle du volume
+  - Mode sélection : Choix de la station radio
+
+#### Interface web
+
+Accédez à l'interface via l'adresse IP de la radio (affichée au démarrage) :
+
+- **🎵 Contrôle de lecture** : Play/Stop/Changement de station
+- **📻 Gestion des stations** : Ajouter/supprimer jusqu'à 10 stations
+- **🌐 Configuration WiFi** : Modifier les paramètres réseau
+- **📱 Compatible mobile** : Interface responsive
+
+### Stations pré-configurées
+
+- France Inter
+- FIP
+- France Info
+- 80s Hits
+- BBC Radio 1
+
+## ⚙️ Pour le développeur
+
+### Prérequis
+
+- **Arduino CLI** installé et configuré
+- **Board ESP32** : `esp32:esp32:esp32`
+- **Bibliothèques** :
+  - ESP32-audioI2S
+  - WiFi (intégrée)
+  - WebServer (intégrée)
+  - EEPROM (intégrée)
+
+### Schéma de câblage
+
+```
+ESP32 Pin  | Composant
+-----------|----------
+25         | I2S_DOUT (vers DAC)
+26         | I2S_LRC (vers DAC)
+27         | I2S_BCLK (vers DAC)
+32         | LED de statut
+33         | Bouton d'alimentation
+34         | Potentiomètre (signal analogique)
+```
+
+### Configuration WiFi
+
+1. Copiez `wifiinfo.h.sample` vers `wifiinfo.h`
+2. Modifiez les paramètres par défaut :
+
+```cpp
+#define WIFI_SSID "VotreSSID"
+#define WIFI_PASSWD "VotreMotDePasse"
+#define HOSTNAME "ESP32-Radio"
+```
+
+### Compilation et upload
+
+#### Méthode simple
+
+```bash
+make all          # Compile + Upload + Monitor
+```
+
+#### Méthode détaillée
+
+```bash
+make compile      # Compilation uniquement
+make upload       # Upload vers ESP32
+make watch        # Monitoring série (screen)
+```
+
+#### Troubleshooting upload
+
+Si l'upload échoue avec "Device or resource busy" :
+
+```bash
+lsof /dev/ttyUSB0        # Vérifier les processus
+kill <PID>               # Tuer le processus si nécessaire
+```
+
+### Architecture du code
+
+#### Fichiers principaux
+
+- `esp32_radio.ino` : Code principal
+- `wifiinfo.h` : Configuration WiFi (non versionné)
+- `Makefile` : Scripts de build
+
+#### Fonctions clés
+
+- `setup()` : Initialisation, gestion du réveil, connexion WiFi
+- `loop()` : Boucle principale (audio, web, contrôles)
+- `wifi_init()` : Gestion intelligente de la connexion WiFi
+- `powerButton()` : Gestion multi-niveau des appuis bouton
+- `volumeAdjust()` : Volume ou sélection selon le mode
+- `handleRoot()` : Interface web principale
+
+#### Stockage EEPROM
+
+```cpp
+EEPROM_SIZE = 2048
+├── WiFi credentials (0-96)
+└── Radio stations (100-2047)
+    ├── Nombre de stations (1 byte)
+    └── Stations (200 bytes chacune)
+```
+
+#### Modes de fonctionnement
+
+1. **Normal** : Lecture + contrôles standard
+2. **Sélection** : Potentiomètre = sélection station
+3. **Configuration** : Point d'accès + interface web
+4. **Deep Sleep** : Réveil par bouton uniquement
+
+### Personnalisation
+
+#### Ajouter des stations par défaut
+
+Modifiez `loadStationsFromEEPROM()` ligne 428-441.
+
+#### Modifier les timeouts
+
+```cpp
+#define CONNECTION_TIMEOUT 10        // Timeout WiFi (secondes)
+#define LONG_PRESS_TIME 2000        // Appui long (ms)
+#define SELECTION_TIMEOUT 5000      // Timeout sélection (ms)
+```
+
+#### Pins personnalisées
+
+Modifiez les defines lignes 9-14 selon votre câblage.
+
+### API Web
+
+- `GET /` : Interface principale
+- `POST /add` : Ajouter station (`name`, `url`)
+- `POST /delete?id=X` : Supprimer station
+- `POST /play?id=X` : Lancer station
+- `POST /stop` : Arrêter + veille
+- `GET /wifi-config` : Interface WiFi
+- `POST /save-wifi` : Sauvegarder WiFi + redémarrage
+- `POST /reset-wifi` : Reset + mode configuration
