Dev_LED_Initialize()

void Dev_LED_Initialize

(

void

)

Returns

void

This function initializes the LED to normal blink interval.

Note

Not really needed to be called at startup, but its nice be consistent

Definition at line 78 of file dev_led.c.

Here is the call graph for this function:

Dev_LED_Off()

void Dev_LED_Off

(

uint8_t

led_id

)

Parameters

led_id

LED ID instance

Returns

void

This function turns off the led with the ID defined in the header file

Definition at line 118 of file dev_led.c.

Dev_LED_On()

void Dev_LED_On

(

uint8_t

led_id

)

Parameters

led_id

LED ID instance
