Standard libraries unknown in IDE V1.5.1r2

Hardware Arduino Due

The math with pointers is failing. I try to add the offset to the base register and it gets a value that I can't explain.

I'm using pin 7 of due.

For this pin, the port address is 400E1200 and PDSR register is 400E123C. This is taken from datasheet.

I've added Serial.println to the reset function to see the backstage.

uint8_t OneWire::reset(void)
{
	IO_REG_TYPE mask = bitmask;
	//volatile IO_REG_TYPE *reg IO_REG_ASM = baseReg;
	volatile IO_REG_TYPE *reg = baseReg;
	//volatile IO_REG_TYPE *regout = baseOutReg;
	Serial.println((long)(&(digitalPinToPort(7)->PIO_PER)),HEX);
	Serial.println((long)(reg),HEX);
	Serial.println((long)(bitmask),HEX);
	volatile uint32_t *value=reg+1;
	Serial.println((uint32_t)value,HEX);
	uint8_t r;
	uint8_t retries = 125;

	noInterrupts();
	DIRECT_MODE_INPUT(reg, mask);
	Serial.println(((*(reg+0x3c))),HEX);

From this serial.print i get:

for -> Serial.println((long)(&(digitalPinToPort(7)->PIO_PER)),HEX);

I have 400E1200

for -> Serial.println((long)(reg),HEX);

I also have 400E1200

for -> Serial.println((long)(bitmask),HEX);

I have 800000

for - > Serial.println((uint32_t)value,HEX);

I have 400E1204 !!!!!!!!!!!!!!

Remenber that I've done this one line before:

volatile uint32_t *value=reg+1;

Why I don't have 400E1201 ????? :astonished:
