Define Documentation

#define HIF_TYPE   (HIF_UART_1)

On the Meshbean board UART1 is routed either via a FT232BM USB converter to connector CN1 or via a RS232 level shifter to header P2. The selection is done with jumper J3.

#define HWTMR_PRESCALE   (1)

• CS1[2:0] = 1 : Prescaler = 1
• WGM1[3:0] = 0 : Mode = 4 : CTC operation

Timer is clocked at F_CPU, and TIMER_IRQ_vect is called every 65535 ticks.

#define LED_DDR   DDRB

DDR register for LED

#define LED_MASK   0xe0

MASK value for LED

#define LED_NUMBER   (3)

number of LEDs for this board

#define LED_PORT   PORTB

PORT register for LED

#define LED_SHIFT   (5)

SHIFT value for LED

#define LEDS_INVERSE   (0)

a 1 at the PORT means the LED is off

#define SLEEP_ON_KEY

(

)

Value:

do{\
            EIMSK |= _BV(INT6);\
            set_sleep_mode(SLEEP_MODE_PWR_DOWN);\
            sleep_mode();\
            EIMSK &= ~_BV(INT6);\
        } while(0)

#define TIMER_INIT

(

)

Value:

do{ \
        TCCR1B |= (_BV(CS10));\
        TIMSK1 |= _BV(TOIE1); \
    }while(0)
