@par Example Description
How to configure and use GPIOs to toggle the on-board user LEDs
every 250 ms. This example is based on the STM32WBxx LL API. The peripheral
is initialized with LL initialization function to demonstrate LL init usage.
PB.00 IO (configured in output pushpull mode) toggles in a forever loop.
On P-NUCLEO-WB55 board this IO is connected to LED2.
In this example, HCLK is configured at 16 MHz.

@par Hardware and Software environment
- This example runs on STM32WB55xx devices.
- This example has been tested with P-NUCLEO-WB55 board and can be
easily tailored to any other supported device and development board.
