LCD Configuration
|
||||
-----------------
|
||||
|
||||
Here is a configuration that enables the LCD with backlight in RGB565
|
||||
color mode. Notice that this configuration sets up an LCD framebuffer of
|
||||
size 6,291,456 (0x0060:0000, 6MiB) at the end of DRAM. DRAM begins at
|
||||
address 0x2000:0000 and has size 268,435,456 (0x1000:0000); The
|
||||
framebuffer the begins at 0x2000:0000 + 0x1000:0000 - 0x0060:0000 =
|
||||
0x2fa0:0000.
|
||||
|
||||
System Type -> SAMA5 Peripheral Support ->
|
||||
CONFIG_SAMA5_LCDC=y : Enable LCDC
|
||||
|
||||
System Type -> LCDC Configuration ->
|
||||
CONFIG_SAMA5_LCDC_BACKLIGHT=y : With backlight
|
||||
CONFIG_SAMA5_LCDC_DEFBACKLIGHT=0xc8
|
||||
CONFIG_SAMA5_LCDC_BACKCOLOR=0x7b5d : Color to use when clearing the display
|
||||
CONFIG_SAMA5_LCDC_FB_VBASE=0x2fa00000 : Set aside the framebuffer
|
||||
CONFIG_SAMA5_LCDC_FB_PBASE=0x2fa00000
|
||||
CONFIG_SAMA5_LCDC_FB_SIZE=6291456
|
||||
CONFIG_SAMA5_LCDC_BASE_ROT0=y : No rotation
|
||||
CONFIG_SAMA5_LCDC_BASE_RGB565=y : RGB565 color format
|
||||
|
||||
This framebuffer size must then be subtracted from the memory available in the
|
||||
heap (0x3000:0000 - 0x0058:0000 = 0x2fa8:0000):
|
||||
|
||||
System Type -> Heap Configuration ->
|
||||
CONFIG_SAMA5_DDRCS_RESERVE=y : Reserve DRAM for the framebuffer
|
||||
CONFIG_SAMA5_DDRCS_HEAP_END=0x2fa00000 : End of DRAM heap (excludes framebuffer)
|
||||
|
||||
There are several simple graphics examples under apps/examples/ that can
|
||||
be use to verify the LCD: nx, nxhello, nximage, nxlines, nxtext. See
|
||||
apps/examples/README.txt for information about configuring these examples.
|
||||
|
||||
For example, these settings will enable the apps/examples/nx example. The
|
||||
NX example is a simple test using the NuttX graphics system (NX). This
|
||||
test case focuses on general window controls, movement, mouse and keyboard
|
||||
input. It requires no user interaction.
|
||||
|
||||
First you need to enable NuttX graphics support:
|
||||
|
||||
Graphics Support ->
|
||||
CONFIG_NX=y : Enable NX graphics
|
||||
CONFIG_NX_NPLANES=1 : 1 color plane
|
||||
CONFIG_NX_PACKEDMSFIRST=y
|
||||
|
||||
Graphics Support -> Supported Pixel Depths ->
|
||||
CONFIG_NX_DISABLE_1BPP=y : Disable all resolutions except 16 bpp
|
||||
CONFIG_NX_DISABLE_2BPP=y
|
||||
CONFIG_NX_DISABLE_4BPP=y
|
||||
CONFIG_NX_DISABLE_8BPP=y
|
||||
CONFIG_NX_DISABLE_24BPP=y
|
||||
CONFIG_NX_DISABLE_32BPP=y
|
||||
|
||||
Graphics Support -> Input Devices ->
|
||||
CONFIG_NX_MOUSE=y : Build in mouse/touchscreen support (not used)
|
||||
CONFIG_NX_KBD=y : Build in keyboard support (not used)
|
||||
|
||||
Graphics Support -> Framed Window Borders ->
|
||||
CONFIG_NXTK_BORDERWIDTH=4 : Framed window configuration
|
||||
CONFIG_NXTK_DEFAULT_BORDERCOLORS=y
|
||||
|
||||
Graphics Support -> Font Selections ->
|
||||
CONFIG_NXFONTS_CHARBITS=7 : Font configuration
|
||||
CONFIG_NXFONT_SERIF22X28B=y
|
||||
|
||||
Then you can enable the NX example:
|
||||
|
||||
Application Configuration -> Examples -> NX graphics example
|
||||
CONFIG_EXAMPLES_NX=y : Enable the NX example
|
||||
CONFIG_EXAMPLES_NX_VPLANE=0 : Use color plane 0
|
||||
CONFIG_EXAMPLES_NX_DEVNO=0 : Use device zero
|
||||
CONFIG_EXAMPLES_NX_DEFAULT_COLORS=y : Use default colors
|
||||
CONFIG_EXAMPLES_NX_DEFAULT_FONT=y : Use default fonts
|
||||
CONFIG_EXAMPLES_NX_BPP=16 : Use 16 bpp
|
||||
CONFIG_EXAMPLES_NX_TOOLBAR_HEIGHT=16 : Configure toolbar
