How to create alias for input, output and data direction registers in Atmel Studio 6? The below code is not working.

---

Code C - [expand]
1
2
#define PUSH_BUTTON_UP PORTB,0
#define PUSH_BUTTON_UP_DIR DDRB,0

You must specify with what core such code will be applied, due to special function registers are located at different addresses depending on each processor.

I am using ATMEGA1284.

I presume you should declare this way:

---

Code C - [expand]
1
2
#define PUSH_BUTTON_UP        PORTB.0
#define PUSH_BUTTON_UP_DIR    DDRB.0
