Bonjour a tous,
Je bute sur un probleme assez simple , j'essaye de gerer une interruption provenant d'un Bp ( PUll UP a l'etat de repos ) donc sur front descendant sur la pin RC0 de mon PIC16F1455. Une lED doit changer d'etat RC3 lorsque le BP est appuyé.
Mais malheuresement lorsque j'appuie sur le BP l'interruption n'est pas geré
Voyez vous un probleme ( le programme a été recuperer sur le forum microchip qui est censé marcher) ?Code:#include <stdio.h> #include <stdlib.h> #include <xc.h> // PIC16F1455 Configuration Bit Settings // CONFIG1 #pragma config FOSC = INTOSC // Oscillator Selection Bits (INTOSC oscillator: I/O function on CLKIN pin) #pragma config WDTE = OFF // Watchdog Timer Enable (WDT disabled) #pragma config PWRTE = OFF // Power-up Timer Enable (PWRT disabled) #pragma config MCLRE = OFF // MCLR Pin Function Select (MCLR/VPP pin function is digital input) #pragma config CP = OFF // Flash Program Memory Code Protection (Program memory code protection is disabled) #pragma config BOREN = OFF // Brown-out Reset Enable (Brown-out Reset disabled) #pragma config CLKOUTEN = OFF // Clock Out Enable (CLKOUT function is disabled.

Je vous remercie
