Arduino.h and wiring_digital.c problem.

Hardware Arduino Due

After doing some tests, I see that it works by putting the code which says cmaglie.

REG_PIOA_OWER = 0xFFFFFFFF;
REG_PIOB_OWER = 0xFFFFFFFF;
REG_PIOC_OWER = 0xFFFFFFFF;

then hit the code.

#define sbi(reg, mask) *reg |= mask
#define cbi(reg, mask) *reg &= ~mask

int led = 13;
volatile uint32_t * Registro;
uint32_t Mascara;

// the setup routine runs once when you press reset:
void setup() {                
  REG_PIOA_OWER = 0xFFFFFFFF;
  REG_PIOB_OWER = 0xFFFFFFFF;
  REG_PIOC_OWER = 0xFFFFFFFF;
  Registro	= portOutputRegister(digitalPinToPort(led));
  Mascara	= digitalPinToBitMask(led);
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);    
  
  
}

// the loop routine runs over and over again forever:
void loop() {
  sbi(Registro,Mascara);
  delay(1000);               // wait for a second
  cbi(Registro,Mascara);
  delay(1000);               // wait for a second
}
