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.

Function Documentation#

halInternalInitLed#

void halInternalInitLed (void )

Configures GPIOs pertaining to the control of LEDs.

Parameters
N/A

Definition at line 70 of file /mnt/raid/workspaces/ws.SZ9MaSA5u/overlay/gsdk/platform/base/hal/micro/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 90 of file /mnt/raid/workspaces/ws.SZ9MaSA5u/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
N/Aled

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


Definition at line 97 of file /mnt/raid/workspaces/ws.SZ9MaSA5u/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
N/Aled

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


Definition at line 104 of file /mnt/raid/workspaces/ws.SZ9MaSA5u/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
N/AturnOn

See Usage.

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