   1 /*
   2      Exemple d'utilisation des fonctions du module comparateurs.
   3   *
   4      valide pour la famille 16f87Xa,
   5   *
   6      En cet exemple on utilise le comparateur 1 con Vref interne al 50\% de Vdd,
   7   *
   8      connecter la tension à comparer à RA0,
   9   *
  10      connecter une led ou une autre sortie à RB7.
  11   *
  12      RB7 se mettra à l'état haut (Vdd) quand la tension en RA0 sera inférieure à 50\% de Vdd
