 * @brief 16x12 R Click example
 *
 * # Description
 * This example demonstrates the usage of the 16x12 R Click board which features a high-brightness
 * red LED matrix display. It displays characters, rotates them in different orientations,
 * prints a scrolling string, and renders a graphical image (MIKROE logo).
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the logger and the Click board and sets the default configuration.
 *
 * ## Application Task
 * Displays single characters and a string in multiple rotations, followed by
 * drawing and inverting the MIKROE logo image.
