Je ne suis pas un expert dans la programmation de pic, et pour tout dire c'est même mon premier projet "complet", donc soyez indulgent si ma question est bête comme bonjour
Bon voilà, je suis en train de réaliser une mini station météo pour mon papa. le besoin est simple:
Affichage des températures avec 2 sondes (DS18B20)
Affichage de la vitesse du vent (signal front haut qui m'arrive d'un autre système).
J'ai programmé avec le compilateur mikroC pro, et j'ai utiliser la carte de développement EasypicV7. Jusque là, tout va bien.
Afin d'être plus clair, je joins le schéma ISIS ainsi que le code MikroC.
Donc sur ma carte tout est ok, et le programme fonctionne super bien.
Je me suis donc mis au soudage...et là soucis,on dirait que mon pic ne démarre pas rien ne se passe....
Quelqu'un aurait une piste????
merci d'avance
