LED#

Sample API funtions for controlling LEDs.

See sl_si91x_led.c for source code.

Modules#

sl_led_t

Functions#

void
sl_si91x_led_init(const sl_led_t *handle)

Configures GPIOs pertaining to the control of LEDs.

void
sl_si91x_led_toggle(uint8_t pin)

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

void
sl_si91x_led_set(uint8_t pin)

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

void
sl_si91x_led_clear(uint8_t pin)

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

void
sl_si91x_led_StackIndicateActivity(bool turnOn)

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

sl_si91x_led_StackIndicateActivity#

void sl_si91x_led_StackIndicateActivity (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.

Returns

  • none
