 ### Guide de l'étudiant
 
+#### Le point d'arrêt
+Placer un point d'arrêt à la ligne 87 (`etat.position = 0;`) permet de s'arrêter juste après l'ajout d'un point à un joueur.
 
+#### Observation des scores
+Ajouter la variable `global.scores` à une *Watch Window* pour visualiser les scores au fil de l’exécution.
+
+#### Afficher le son dans le débugueur :
+
+1. Ouvrir le Logic Analyzer
+2. Cliquer sur Setup
+3. Ajouter un nouveau signal *TIM3_CCR3* en mode analogique.
+4. Lancer l'exécution.
+
+Et si le son n'est pas entièrement visible :
+
+5. Dans *Zoom*, cliquer sur *All*
+6. Dans *Min/Max*, cliquer sur *Auto*
+
+#### Visualisations optionnelles
+Deux bits du *GPIOB* sont utilisés lors de l’exécution. Il est possible de les observer avec le *Logic Analyser* :
+* Le `portb.1` qui est à 1 lors de l'exécution de la fonction `sys_callback`
+* Le `portb.14` qui est mis brièvement à 1 à chaque modification des scores
