Programme avec un PIC 16F876

Bonjour

Voici une partie de mon programme
pouvez vous me dire s'il est à peu près correcte et si la configuration du can est bonne? (je ne sais pas comment on fait pour récupérer la valeur qu'il convertit?)

J'ai oublié de dire que je fais le programme en C

la tu as la datasheet complète de ton pic.
il faut que tu commence par paramétrer le convertiseur analogique/numérique (tu trouveras tout sur le liens plus haut). une fois configuré, un while(1){......} et tu remplace les ..... par le code pour lancer la convertion et tu compares avec tes valeurs de plage
if(resultat_conv > plage_min && resultat_plage < plage_max)
//allume une led
else
// allume l'autre led.
