 * @file main.c
 * @brief LCDmini Click example
 *
 * # Description
 * This is an example that demonstrates the use of the LCD mini Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization driver enables - SPI, performing hardware reset, default config, 
 * setting up the backlight, and entering text to be written.
 *
 * ## Application Task
 * This example shows the written text, then the text is moved left, 
 * with changing between rows of the LCD screen.
 *
 * @note If the screen isn't initialized you may need to restart the device.
