@par Example Description
This example describes how to configure and use GPIOs to toggle every 250 ms
the user LEDs available on the board. This example is based on the STM32F4xx
LL API. Peripheral initialization is done using LL initialization function to
demonstrate LL init usage.
PA.05 IO (configured in output pushpull mode) toggles in a forever loop.
On NUCLEO-F411RE board this IO is connected to LED2.
In this example, HCLK is configured at 100 MHz.
@par Keywords
System, GPIO, Output, Alternate function, Push-pull, Toggle
