CONFIGURAÇÃO ENTRADA ANALOGICA PIC16F628

[jandom]

Senhores, estou com dificuldade de configurar os pinos A0 a A4 funcionar com entradas, pois no programa abaixo ao acionar a IN1, o programa passa adiante!


#define OUT1 pin_B5 // pino 11
#define OUT2 pin_B4 // pino 10

#define IN1 pin_a1 // pino 18
#define IN2 pin_A0 // pino 17
#define IN3 pin_a2 // pino 1
#define IN4 pin_a3 // pino 2

WHILE(TRUE)
{
IF((INPUT(IN1)) || (INPUT(IN2))) BREAK;
}

estou colocando resistores pull down de 1k e em pararelo capacitor de 100nF e diodo zener de 5v1 para proteção nas entradas, já troquei o PIC e nada!!!
Alguém já passou por isso?

Vc desligou os comparadores ???

Fabim, onde modifico isto? no header?
