This is a simple example that just puts the NuttX logo image in the center
|
||||
of the display. This only works for RGB23 (888), RGB16 (656), and RGB8 (332
|
||||
for now.
|
||||
|
||||
CONFIG_EXAMPLES_NXIMAGE_BUILTIN -- Build the NXIMAGE example as a "built-in"
|
||||
that can be executed from the NSH command line
|
||||
CONFIG_EXAMPLES_NXIMAGE_VPLANE -- The plane to select from the frame-
|
||||
buffer driver for use in the test. Default: 0
|
||||
CONFIG_EXAMPLES_NXIMAGE_DEVNO - The LCD device to select from the LCD
|
||||
driver for use in the test: Default: 0
|
||||
CONFIG_EXAMPLES_NXIMAGE_BPP -- Pixels per pixel to use. Valid options
|
||||
include 8, 16, and 24. Default is 16.
|
||||
CONFIG_EXAMPLES_NXIMAGE_XSCALEp5, CONFIG_EXAMPLES_NXIMAGE_XSCALE1p5,
|
||||
CONFIG_EXAMPLES_NXIMAGE_XSCALE2p0 -- The logo image width is 160 columns.
|
||||
One of these may be defined to rescale the image horizontally by .5, 1.5,
|
||||
or 2.0.
|
||||
CONFIG_EXAMPLES_NXIMAGE_YSCALEp5, CONFIG_EXAMPLES_NXIMAGE_YSCALE1p5,
|
||||
CONFIG_EXAMPLES_NXIMAGE_YSCALE2p0 -- The logo image height is 160 rows.
|
||||
One of these may be defined to rescale the image vertically by .5, 1.5,
|
||||
or 2.0.
|
||||
CONFIG_EXAMPLES_NXIMAGE_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
|
||||
|
||||
NOTE: As of this writing, not all of the scaling options and combinations
|
||||
have been tested.
