config NX
bool "NX Graphics"
default n
---help---
Enables overall support for graphics library and NX
if NX
config NX_LCDDRIVER
bool "LCD driver"
default y
depends on LCD
---help---
By default, the NX graphics system uses the frame buffer driver interface
defined in include/nuttx/video/fb.h. However, if LCD is support is enabled,
this this option is provide to select, instead, the LCD driver interface
defined in include/nuttx/lcd/lcd.h.
config NX_NPLANES
int "Number of Color Planes"
default 1
---help---
Some YUV color formats requires support for multiple planes, one for
each color component. Unless you have such special hardware (and
are willing to debug a lot of untested logic), this value should be
set to 1.
config NX_BGCOLOR
hex "Initial background color"
default 0x0
---help---
NX will clear the background plane initially. This is the default
color that will be used when the background is cleared. Note: This
logic would have to be extended if you want to support multiple
color planes.
config NX_ANTIALIASING
bool "Anti-aliasing support"
default n
depends on (!NX_DISABLE_16BPP || !NX_DISABLE_24BPP || !NX_DISABLE_32BPP) && !NX_LCDDRIVER
---help---
Enable support for ant-aliasing when rendering lines as various
orientations.
config NX_WRITEONLY
bool "Write-only Graphics Device"
default y if NX_LCDDRIVER && LCD_NOGETRUN
default n if !NX_LCDDRIVER || !LCD_NOGETRUN
---help---
Define if the underlying graphics device does not support read operations.
Automatically defined if NX_LCDDRIVER and LCD_NOGETRUN are
defined.
config NX_UPDATE
bool "Display update hooks"
default n
---help---
Enable a callout to inform some external module that the display has
been updated. This would be useful in a couple for cases.
- When a serial LCD is used, but a framebuffer is used to access the
LCD. In this case, the update callout can be used to refresh the
affected region of the display.
- When VNC is enabled. This is case, this callout is necessary to
update the remote frame buffer to match the local framebuffer.
When this feature is enabled, some external logic must provide this
interface:
void nx_notify_rectangle(FAR NX_PLANEINFOTYPE *pinfo,
FAR const struct nxgl_rect_s *rect);
That is the function that will handle the notification. It
receives the rectangular region that was updated in the provided
plane.
menu "Supported Pixel Depths"
config NX_DISABLE_1BPP
bool "Disable 1 BPP"
default y
---help---
NX supports a variety of pixel depths. You can save some memory by disabling

pixel depth.
config NX_DISABLE_2BPP

---help---
NX supports a variety of pixel depths. You can save some memory by disabling
support for unused color depths. The selection disables support for 2BPP

pixel depth.

pixel depth.
config NX_DISABLE_32BPP

support for unused color depths. The selection disables support for 32BPP
pixel depth.

---help---
X/Y positional input is provided by a mouse. The only difference
between the mouse and touchscreen selection is in the presence or
absence of the mouse buttons. This difference is not used within
NuttX itself, however, graphics applications may need this
information, for example, to handle the different ways that graphic
elements are selected and dragged.
config NX_XYINPUT_TOUCHSCREEN
bool "Touchscreen device support"

---help---
X/Y positional input is provided by a touchscreen. The only difference
between the mouse and touchscreen selection is in the presence or

The bitmap code to use as the cursor. Default '_' (137)
config NXTERM_MXCHARS
int "Max Characters on Display"

---help---
NxTerm needs to remember every character written to the console so
that it can redraw the window. This setting determines the size of some
internal memory allocations used to hold the character data. Default: 128.
config NXTERM_CACHESIZE
int "Font Cache Size"
default 16
---help---
NxTerm supports caching of rendered fonts. This font caching is required
for two reasons: (1) First, it improves text performance, but more
importantly (2) it preserves the font memory. Since the NX server runs on
a separate server thread, it requires that the rendered font memory persist
until the server has a chance to render the font. Unfortunately, the font
cache would be quite large if all fonts were saved. The NXTERM_CACHESIZE
setting will control the size of the font cache (in number of glyphs). Only that
number of the most recently used glyphs will be retained. Default: 16.
NOTE: There can still be a race condition between the NxTerm driver and the
NX task. If you every see character corruption (especially when printing
a lot of data or scrolling), then increasing the value of NXTERM_CACHESIZE
is something that you should try. Alternatively, you can reduce the size of
MQ_MAXMSGSIZE which will force NxTerm task to pace the server task.
NXTERM_CACHESIZE should be larger than MQ_MAXMSGSIZE in any event.
