Buenas tardes amigos picadictos!
Estoy trabajando en un proyecto para enviar y adquirir datos del pic18f4550 al pc de forma simulada con el proteus! aunque debería ser muy sencillo no lo he podido lograr debido a que el windows no me reconoce el driver pertinente!
-Trabajo con xp de 32 bits sp3 emulado por vmware por los problemas del windows 7!
-programo en ccs ver 4.104
-proteus 7.8 sp2
He leido cantidad de foros y nada no hay manera!
este es el codigo de prueba
#include<18F4550.H>

He colocado todos los archivos en la misma capeta!
el windows detecta el hardware ! pero cuando le doy instalar desde la ubicacion donde esta el driver no lo reconoce y ya no se que mas hacer
! Les agradeceria una mano pues ya tengo tiempo con esto y no hay manera! cualquier sugerencia será bien recibida!
