#define AVR_ENTER_CRITICAL_REGION

(

)

Value:

uint8_t volatile saved_sreg = SREG; \
                                     cli();

This macro will protect the following code from interrupts.

#define AVR_LEAVE_CRITICAL_REGION

(

)

SREG = saved_sreg;

This macro must always be used in conjunction with AVR_ENTER_CRITICAL_REGION so the interrupts are enabled again.

#define delay_us

(

us

)

(_delay_us( us ))

Define the delay_us macro for GCC.

#define F_CPU   8000000UL

Define default CPU frequency, if this is not already defined.

#define INLINE   static inline

#define MAIN_TASK_EPILOGUE

(

)

return -1;

#define MAIN_TASK_PROLOGUE   int

#define nop

(

)

do { __asm__ __volatile__ ("nop"); } while (0)

Define the no operation macro.

#define SHORTENUM   __attribute__ ((packed))
