NxConsole is a write-only character device (not shown) that is built on top of an NX window.
|

This character device can be used to provide <code>stdout</code> and <code>stderr</code> and, hence, can provide the output side of NuttX console.

(font ID FONTID_SERIF38X49B == 13).
|
||||
|
||||
NxConsole Configuration Settings:
|
||||
|
||||
CONFIG_NXCONSOLE_BPP
|
||||
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 CONFIG_NX_DISABLE_*BPP)
|
||||
CONFIG_NXCONSOLE_NOGETRUN
|
||||
NxConsole needs to know if it can read from the LCD or not. If reading
|
||||
from the LCD is supported, then NxConsole can do more efficient
|
||||
scrolling. Default: Supported
|
||||
CONFIG_NXCONSOLE_MXCHARS
|
||||
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_NXCONSOLE_FONTCACHE
|
||||
If this setting is defined, then caching of fonts will be supported by
|
||||
NxConsole. Each font must be rendered from the tiny font storage format
|
||||
to the full display size and pixel depth. If this setting is defined, then
|
||||
the more recently used font glyphs will be retained in a cache of size
|
||||
CONFIG_NXCONSOLE_CACHESIZE. Default: No font caching.
|
||||
CONFIG_NXCONSOLE_CACHESIZE
|
||||
If CONFIG_NXCONSOLE_FONTCACHE, then this setting will control the size
|
||||
of the font cache (in number of glyphs). Default: 16.
|
||||
CONFIG_NXCONSOLE_LINESEPARATION
|
||||
This the space (in rows) between each row of test. Default: 2
|
||||
CONFIG_NXCONSOLE_NOWRAP
|
||||
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.

* only.
