----------in English-----------
I am trying read, the pin 5 (GPIO) in the TS-7400, in this moment, i have this 
code:

int main(){
/* PRIMERO ABRO EL PING */
int fd=open("/dev/mem",O_RDWR|O_SYNC);
if(fd<0){
printf("No se pudo abrir la memoria \n");
        }
else{
printf("Registro de memoria abierto - fd = %fd \n",fd);
    }

This code , open the memory.
My question is, ¿how i finish the code, for read GPIO pin?

Thanks

I sorry for my language, I am live Chile.

Regards

Andrés

Bueno, lo que quiero es leer el ping 5 (GPIO) de la placa TS7400.
Hasta ahora tengo este codigo, que abre la memoria, segun entiendo.El cual 
funciona correctamente.

int main(){
/* PRIMERO ABRO EL PING */
int fd=open("/dev/mem",O_RDWR|O_SYNC);
if(fd<0){
printf("No se pudo abrir la memoria \n");
        }
else{
printf("Registro de memoria abierto - fd = %fd \n",fd);
    }
}

ahora lo que tengo que agregar el codigo es como leer un pin GPIO
creo que la respuesta va por un codigo similar a esto:
mmap(NULL, 0x10000, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0x49050000);
pero no entiendo bien como hacerlo.

Gracias de antemano

Saludos

Andrés
