		The LCD device to select from the LCD driver for use in the test:
		Default: 0

config EXAMPLES_NXDEMO_BGCOLOR
	hex "Background color"
	default 0x0
	---help---
		The color of the background.  Default depends on config
		EXAMPLES_NXDEMO_BPP.

config EXAMPLES_NXDEMO_EXTERNINIT
	bool "External Device Initialization"
	default n
	depends on BOARDCTL
	select BOARDCTL_GRAPHICS
	---help---
		The driver for the graphics device on this platform requires some
		unusual initialization.  This is the case, for example, for SPI LCD/OLED
		devices.  If this configuration is selected, then the platform code
		must provide an LCD initialization function with a prototype like:

		#ifdef CONFIG_NX_LCDDRIVER
		FAR struct lcd_dev_s *board_graphics_setup(unsigned int devno);
		#else
		FAR struct fb_vtable_s *board_graphics_setup(unsigned int devno);
		#endif

		and must also define: CONFIG_BOARDCTL=y and
		CONFIG_BOARDCTL_GRAPHICS=y so that the boardctl() interface
		will be available in order to access this function.
