 * \brief SemperFlash Click example
 * 
 * # Description
 * This example showcases how to initialize and use the Semper Flash click. The click
 * is a 512 Mbit SPI Flash memory module. Data can be stored in and read from the flash
 * memory. There's also the option of erasing it's contents. Here's how to do it.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the click and logger modules. Additional con-
 * figuring is done in the default_cfg(...) function. The device ID should appear in the 
 * UART console if the setup finishes successfully.
 * 
 * ## Application Task  
 * This function first erases the contents of the flash memory and then writes, reads and
 * prints two strings in the UART console. It does so every 2 seconds.
