#define HEART_BLUE   GPIO_PIN_2

Definition at line 31 of file heartbeat.h.

Referenced by heart_beat(), heart_init(), heart_off(), heart_on(), heart_status(), and heart_toggle().

#define HEART_GREEN   GPIO_PIN_3

Definition at line 32 of file heartbeat.h.

#define HEART_RED   GPIO_PIN_1

The on-board LED colloquially referred to as the 'heart.' Does every computer have one?

Definition at line 30 of file heartbeat.h.

#define heart_wrap

(

x

)

Value:

heart_beat();     \
    x                 \
    heart_toggle();   \

Surround the execution of a code block with two hooks.

• pre_hook: heart_beat();
• post_hook: heart_toggle();

Definition at line 132 of file heartbeat.h.

#define THORACIC_CAVITY   GPIO_PORTF_BASE

The GPIO base where the may be found. Otherwise knows as a subdivision of the ventral body cavity which houses the heart.
