 * @brief LED Flash 4 Click example
 *
 * # Description
 * This example demonstrates the use of LED Flash 4 click board by toggling
 * the LEDs output.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration which sets
 * the click in flash mode with the LED current of 50mA for both LEDs. The strobe
 * pin is set to active high level type.

 * ## Application Task
 * Toggles the LEDs output every 2 seconds using the strobe pin, and displays the LEDs
 * state on the USB UART.
