LED Control#

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

HalBoardLed

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

Functions#

void

halInternalInitLed(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

halStackIndicateActivity(bool turnOn)

Called by the stack to indicate activity over the radio (for both transmission and reception). It is called once with turnOn true and shortly thereafter with turnOn false.

halToggleLed#

void halToggleLed (HalBoardLed led)

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

Parameters

Type	Direction	Argument Name	Description
HalBoardLed	N/A	led	Identifier (from BOARD_HEADER) for the LED to be toggled.

Definition at line 90 of file /mnt/raid/workspaces/ws.tfWcRzYcf/overlay/gsdk/platform/base/hal/micro/led.h

halSetLed#

void halSetLed (HalBoardLed led)

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

Parameters

Type	Direction	Argument Name	Description
HalBoardLed	N/A	led	Identifier (from BOARD_HEADER) for the LED to turn on.

Definition at line 97 of file /mnt/raid/workspaces/ws.tfWcRzYcf/overlay/gsdk/platform/base/hal/micro/led.h

halClearLed#

void halClearLed (HalBoardLed led)

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

Parameters

Type	Direction	Argument Name	Description
HalBoardLed	N/A	led	Identifier (from BOARD_HEADER) for the LED to turn off.

Definition at line 104 of file /mnt/raid/workspaces/ws.tfWcRzYcf/overlay/gsdk/platform/base/hal/micro/led.h

halStackIndicateActivity#

void halStackIndicateActivity (bool turnOn)

Called by the stack to indicate activity over the radio (for both transmission and reception). It is called once with turnOn true and shortly thereafter with turnOn false.

Parameters

Type	Direction	Argument Name	Description
bool	N/A	turnOn	See Usage.

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