+^^^^^^^^^^^^^^^^
+
+ A very simple graphics example that just says "Hello, World!" in the
+ center of the display.
+
+ The following configuration options can be selected:
+
+ CONFIG_EXAMPLES_NXHELLO_BUILTIN -- Build the NXHELLO example as a "built-in"
+ that can be executed from the NSH command line
+ CONFIG_EXAMPLES_NXHELLO_VPLANE -- The plane to select from the frame-
+ buffer driver for use in the test. Default: 0
+ CONFIG_EXAMPLES_NXHELLO_DEVNO - The LCD device to select from the LCD
+ driver for use in the test: Default: 0
+ CONFIG_EXAMPLES_NXHELLO_BGCOLOR -- The color of the background. Default
+ depends on CONFIG_EXAMPLES_NXHELLO_BPP.
+ CONFIG_EXAMPLES_NXHELLO_FONTCOLOR -- The color of the fonts used in the
+ background window. Default depends on CONFIG_EXAMPLES_NXHELLO_BPP.
+ CONFIG_EXAMPLES_NXHELLO_BPP -- Pixels per pixel to use. Valid options
+ include 2, 4, 8, 16, 24, and 32. Default is 32.
+ CONFIG_EXAMPLES_NXHELLO_EXTERNINIT - The driver for the graphics device on
+ this platform requires some unusual initialization. This is the
+ for, for example, 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 *up_nxdrvinit(unsigned int devno);
+ #else
+ FAR struct fb_vtable_s *up_nxdrvinit(unsigned int devno);
+ #endif
