	* \page sam_component_ili93xx_quickstart Quick Start Guide for the ILI93XX
	* LCD Glass component.
	*
	* This is the quick start guide for the \ref ili93xx_display_group, with
	* step-by-step instructions on how to configure and use the driver for
	* a specific use case.The code examples can be copied into e.g the main
	* application loop or any other function that will need to control the
	* ili93xx LCD Glass component module. Now ili9325 and ili9341 are supported.
	*
	* \section ili93xx_qs_use_cases Use cases
	* - \ref ili93xx_basic
	*
	* \section ili93xx_basic ili93xx LCD Glass basic usage
	*
	* This use case will demonstrate how to initialize the ili93xx LCD Glass
	* module.
	*
	*
	* \section ili93xx_basic_setup Setup steps
	*
	* \subsection ili93xx_basic_prereq Prerequisites
	*
	* This module requires the following driver
	* - \ref smc_group
	*
	* \subsection ili93xx_basic_setup_code
	*
	* Add this to the main loop or a setup function:
	* \code
	* struct ili93xx_opt_t g_ili93xx_display_opt;
	* g_ili93xx_display_opt.ul_width = ILI93XX_LCD_WIDTH;
	* g_ili93xx_display_opt.ul_height = ILI93XX_LCD_HEIGHT;
	* g_ili93xx_display_opt.foreground_color = COLOR_BLACK;
	* g_ili93xx_display_opt.background_color = COLOR_WHITE;
	* ili93xx_init(&g_ili93xx_display_opt);
	* \endcode
