LED#

Sample API funtions for controlling LEDs.

When specifying an LED to use, always use the BOARDLEDx definitions that are defined within the BOARD_HEADER.

See led.h for source code.

Typedefs#

typedef enum HalBoardLedPins

Ensures that the definitions from the BOARD_HEADER are always used as parameters to the LED functions.

Functions#

void

Configures GPIOs pertaining to the control of LEDs.

void
halToggleLed(HalBoardLed led)

Atomically wraps an XOR or similar operation for a single GPIO pin attached to an LED.

void
halSetLed(HalBoardLed led)

Turns on (sets) a GPIO pin connected to an LED so that the LED turns on.

void
halClearLed(HalBoardLed led)

Turns off (clears) a GPIO pin connected to an LED, which turns off the LED.

void

Called by the stack to indicate activity over the radio (for both transmission and reception).

Function Documentation#

halInternalInitLed#

void halInternalInitLed (void )

Configures GPIOs pertaining to the control of LEDs.

Parameters
N/A

Definition at line 72 of file platform/service/legacy_hal/inc/led.h

halToggleLed#

void halToggleLed (HalBoardLed led)

Atomically wraps an XOR or similar operation for a single GPIO pin attached to an LED.

Parameters
N/Aled

Identifier (from BOARD_HEADER) for the LED to be toggled.


Definition at line 92 of file platform/service/legacy_hal/inc/led.h

halSetLed#

void halSetLed (HalBoardLed led)

Turns on (sets) a GPIO pin connected to an LED so that the LED turns on.

Parameters
N/Aled

Identifier (from BOARD_HEADER) for the LED to turn on.


Definition at line 99 of file platform/service/legacy_hal/inc/led.h

halClearLed#

void halClearLed (HalBoardLed led)

Turns off (clears) a GPIO pin connected to an LED, which turns off the LED.

Parameters
N/Aled

Identifier (from BOARD_HEADER) for the LED to turn off.

halStackIndicateActivity#

void halStackIndicateActivity (bool turnOn)

Called by the stack to indicate activity over the radio (for both transmission and reception).

Parameters
N/AturnOn

See Usage.

It is called once with turnOn true and shortly thereafter with turnOn false.

Typically does something interesting, such as change the state of an LED.
