Hola,
Al pulsar el pulsador que tiene asociado el PIC en la entrada RE.3 del PIC 18F26K22, la entrada no responde
y va directamente a la linea "OK Freno ...".
El fusible "MCLRE" esta deshabilitado y pasa ha ser entrada digital tal como pone el datasheet en la página 151.
También incluyo foto del esquema pulsador. al pulsar, el PIC recibe 1 mientras tiene un 0 en la entrada.
