LED#

Sample API funtions for controlling LEDs.

See sl_si91x_led.c for source code.

Introduction#

The SI91x LED driver is a platform-level software module responsible for managing the control of LEDs. All LED functions are called through the generic driver, which then which internally calls functions specific to the LED.

Configuration#

All LED instances are configured with an sl_led_t struct. This struct is automatically generated after a LED is set up using Simplicity Studio's wizard.

• For more information on configuring available parameters refer to the respective peripheral example readme document and refer here https://docs.silabs.com/wiseconnect/latest/wiseconnect-api-reference-guide-si91x-peripherals/disable-uc-config.

Usage#

Once the LED structs are defined, the LED functions can be called being passed an instance of sl_led_t, which will be redirected to calling the type specific version of that function. The common functions include the following:

• sl_si91x_led_init

• sl_si91x_led_toggle

• sl_si91x_led_set

• sl_si91x_led_clear

sl_led_init initialises the specific LED. This function is called automatically when the application is run.

sl_si91x_led_toggle can be implemented by the application if required. This function is used to toggle the state of the LED. sl_si91x_led_set and sl_si91x_led_clear both can be implemented by the application. These functions are used to turn the LED on and off resectively.
