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.

---help---
There is no X/Y positional input device connected
config NX_XYINPUT_MOUSE
bool "Mouse device support"
select NX_XYINPUT
---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"
select NX_XYINPUT
---help---
X/Y positional input is provided by a touchscreen. The only difference
between the mouse and touchscreen selection is in the presence or

---help---
Currently, NxConsole supports only a single pixel depth. This
configuration setting must be provided to support that single pixel depth.
Default: The smallest enabled pixel depth. (see NX_DISABLE_*BPP)
config NXTERM_CURSORCHAR
int "Character code to use as the cursor"
default 137
---help---
The bitmap code to use as the cursor. Default '_' (137)
config NXTERM_MXCHARS
int "Max Characters on Display"
default 128
---help---
NxConsole 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---
NxConsole 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 NxConsole 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 NxConsole task to pace the server task.
NXTERM_CACHESIZE should be larger than MQ_MAXMSGSIZE in any event.
config NXTERM_LINESEPARATION
int "Line Separation"
default 0
---help---
This the space (in rows) between each row of test. Default: 0
config NXTERM_NOWRAP
bool "No wrap"
default n
---help---
By default, lines will wrap when the test reaches the right hand side
of the window. This setting can be defining to change this behavior so
that the text is simply truncated until a new line is encountered.
comment "NxConsole Input options"
config NXTERM_NXKBDIN
bool "NX KBD input"
default n
---help---
Take input from the NX keyboard input callback. By default, keyboard
input is taken from stdin (/dev/console). If this option is set, then
the interface nxcon_kdbin() is enabled. That interface may be driven
by window callback functions so that keyboard input *only* goes to the
top window.
config NXTERM_KBDBUFSIZE
int "Keyboard Input Buffer Size"
default 16
---help---
If NXTERM_NXKBDIN is enabled, then this value may be used to
define the size of the per-window keyboard input buffer. Default: 16
config NXTERM_NPOLLWAITERS
int "Number of Poll Waiters"
default 4
---help---
The number of threads that can be waiting for read data available.
Default: 4

---help---
Open the client message queues in blocking mode. In this case,
nx_eventhandler() will not return until a message is received and processed.
config NX_MXSERVERMSGS
int "Max Server Messages"
default 32
---help---
Specifies the maximum number of messages that can fit in the message queues.
No additional resources are allocated, but this can be set to prevent
flooding of the client or server with too many messages (PREALLOC_MQ_MSGS
controls how many messages are pre-allocated).
config NX_MXCLIENTMSGS
int "Max Client Messages"
default 16
---help---
Specifies the maximum number of messages that can fit in the message queues.
No additional resources are allocated, but this can be set to prevent
flooding of the client or server with too many messages (PREALLOC_MQ_MSGS
controls how many messages are pre-allocated).
config NX_NXSTART
bool "nx_start()"
default n
---help---
If this option is selected, then the nx_start() interface will be
built. The nx_start() interface provides a single call to initialize
and start the NX server.
if NX_NXSTART
config NXSTART_EXTERNINIT
bool "External display Initialization"
default n
---help---
Define to support external display initialization by platform-
specific code. This this option is defined, then nx_start() will
call up_nxdrvinit(CONFIG_NXSTART_DEVNO) to initialize the graphics
device. This option is necessary if display is used that cannot be
initialized using the standard LCD or framebuffer interfaces.
config NXSTART_SERVERPRIO
int "NX Server priority"
default 110
---help---
Priority of the NX server. This applies only if NX is configured in
multi-user mode (NX_MULTIUSER=y). Default: 110.
NOTE: NXSTART_SERVERPRIO should have a relatively high priority to
avoid data overrun race conditions.
config NXSTART_SERVERSTACK
int "NX Server Stack Size"
default 2048
---help---
NX server thread stack size (in multi-user mode). Default 2048
config NXSTART_DEVNO
