# Question on tasks
## Task 5
Comme prochaine tâche, nous voulons analyser les temps d'exécution des différents composants du logiciel.
En principe, nous avons deux composants qui peuvent être exécutés à deux vitesses différentes :
|#|Composant|Timing|
|--|--|--|
|1|Conversion du signal analogue|1 kHz ou plus|
|2|Rafraichissement de l'écran|20 à 60 fois par seconde|
### Question 1
> Est-ce qu'il est possible d'exécuter le composant #1 avec un XF (ou un RTOS) ? Justifiez votre réponse.
Il vaut mieux utiliser un timer hardward pour aller plus vite
### Question 2
> Est-ce qu'il est possible d'exécuter le composant #2 avec un XF (ou un RTOS) ? Justifiez votre réponse.
La vitesse d'un XF est largement suffisante. Le temps le plus rapide est de 1/60 = 16,7ms.
Avec des ticks toutes les millisecondes, le XF est largement capable
### Question 3
> Si l'on combine un timer hardware avec un XF, lequel des deux composants doit être priorisé ? Justifiez votre réponse.
La conversion du signal analogue doit être prioritaire. On doit donc mettre la priorité sur le timer hard.
## Task 7
### Question 1
> Combien de mesures [Samples/s] le convertisseur A/D doit-il effectuer par seconde pour pouvoir échantillonner des signaux avec des fréquences jusqu'à 1 kHz ?
Tout dépend de la résolution souhaitée. Il nous faut au miminum 2 fois la fréquence la plus élevée de notre signal.
Dans notre cas, il nous faut au minimu fs = 2*1kHz = 2kHz
### Question 2
> Faut-il un filtre ? Si oui, quelle sera la fréquence de coupure de ce filtre ?
Oui pour éviter les fréquences de repliement.
Il faut le dimensionner à Fs/2
### Question 3
> Est-ce la fréquence donnée par le théorème d’échantillonnage ou devrait-elle être plus élevée ?
Il nous faudra beaucoup plus que 2 points par sinus. Tout dépend de la résolution souhaitée
### Question 4
> Lequel des canaux du ADC3 doit être utilisé pour pouvoir mesurer / échantillonner le signal à l'aide de la broche PA0 ?
Il faut utiliser le chanal ADC3_IN0
### Question 5
> Est-ce que le ADC pourrait éventuellement effectuer des mesures à des intervalles réguliers à l'aide de ses propres moyens ?
Pour que l'ADC effectue des mesures par ses propres moyens il faudrait le mettre en mode continu.
Mais se ne serait pas à interval régulier, il effectuerait une mesure dès la précédente terminée.
