The 31<sup>st</sup> release of NuttX (nuttx-0.3.19) is available for download
|
||||
<p><b>nuttx-0.4.0</b>.
|
||||
The 32<sup>nd</sup> release of NuttX (nuttx-0.4.10) is available for download
|
||||
from the <a href="http://sourceforge.net/project/showfiles.php?group_id=189573">SourceForge</a>
|
||||
website.
|
||||
The change log associated with the release is available <a href="#currentrelease">here</a>.
|
||||
Unreleased changes after this release are available in CVS.
|
||||
These unreleased changes are listed <a href="#pendingchanges">here</a>.
|
||||
</p>
|
||||
<p>
|
||||
This release includes the following new feature:
|
||||
<p>
|
||||
<ul>
|
||||
<li>Add <code>poll()</code> and <code>select()</code> APIs that may be used to monitor for data
|
||||
availability on character devices or TCP/IP sockets.
|
||||
</li>
|
||||
<li>Implemented support TCP/IP connection backlog.
|
||||
This allows <code>poll()</code>/<code>select()</code> to wake-up on new connections to a listener socket.
|
||||
</li>
|
||||
<li>Added definition of a framebuffer driver and implement framebuffer drivers for the
|
||||
simulated platform and the TI DM320 (untested as of the initial check-in).
|
||||
</li>
|
||||
<li>Partially developed a graphics framework based on the framebuffer drivers, however,
|
||||
this will not be ready for use for a few more release.
|
||||
Currently this includes only a few color conversion routines and some rasterizing functions.
|
||||
A tiny windowing system is under development but not ready for check-in yet.
|
||||
<li>Added support for fixed precision math.
|
||||
</li>
|
||||
<li>Added support for outgoing multicast packets.
|
||||
</li>
|
||||
</ul>
|
||||
<p>
|
||||
Several bugs were fixed, the most important of which are:
|
||||
This release adds graphics support and a tiny windowing subsystem.
|
||||
That new graphics subystem is documented in a <a href="NXGraphicsSubsystem.html">user manual</a>.
|
||||
No other substantial changes were made.
|
||||
</p>
|
||||
<li>Fixed an important bug in the TCP/IP buffering logic.
|
||||
When TCP/IP read-ahead is enabled and not recv() is in-place when a TCP/IP packet is received,
|
||||
the packet is placed into a read-ahead buffer.
|
||||
However, the old contents of the read-ahead buffer were not being cleared and old data would
|
||||
contaminate the newly received buffer.
|
||||
</li>
|
||||
<li>Changed the behavior of the serial driver read.
|
||||
It now returns data as it is available rather than waiting for the full requested read size.
|
||||
This makes functions like <code>fgetc()</code> work much more smoothly.
|
||||
</li>
|
||||
<p>
|
||||
These changes were verified only on the Neuros OSD (ARM) and the Linux simulator using a
|
||||
Linux development environment.
|
||||
The version number was bumped up to 0.4.0 in part to reflect the new graphics subsystem,
|
||||
but also to recognize the NuttX is approaching complete functionality. In the 0.3.x
|
||||
versions, network support was added, Pascal P-code runtime support was added, FAT and
|
||||
ROMFS filesystems were added, MMC/SD and USB device support were added. There were
|
||||
also numerous extensions to the NuttShell, NuttX APIs, and architecture ports.
|
||||
</p>
|
||||
<p>
|
||||
These changes were verified only on the NuttX simulation platform with X11 windows
|
||||
simulating a device framebuffer.
|
||||
Please report any errors to me.
|
||||

nuttx-0.3.19 2008-xx-xx Gregory Nutt <spudmonkey@racsa.co.cr>
|
||||
* Add poll() and select() APIs (in the initial check-in, these work only with character devices)
|
||||
* Add poll() methods to /dev/null, /dev/zero, pipes, fifos, and serial drivers.
|
||||
* Add examples/poll for testing poll() and select()
|
||||
* Fix hostile behavior of getc, fgetc, getchar, etc.: the serial driver was waiting for a
|
||||
full buffer of read data before return. This means that getc would stall when it needed
|
||||
to refill the input buffer. The old behavior (read full blocks) might be useful in other
|
||||
contexts, so it is still available within the driver as a configuration option.
|
||||
* Implement poll() and select() support for TCP/IP sockets
|
||||
* Fixed an important bug in the TCP/IP buffering logic. When TCP/IP read-ahead is enabled
|
||||
and not recv() is in-place when a TCP/IP packet is received, the packet is placed into
|
||||
a read-ahead buffer. However, the old contents of the read-ahead buffer were not being
|
||||
cleared and old data would contaminate the newly received buffer.
|
||||
* Implemented support for connection backlog. The size of the backlog is specified by the
|
||||
second argument of the standard listen() API. Hooks are provided to support poll()/select()
|
||||
waiting for connections, with a subsequent call to accept() to use the backlogged connection.
|
||||
* Fixed a minor bug in accept(). It should allow the address and addresslen values to be NULL
|
||||
* Added first-cut definition for a framebuffer interface (and simulated framebuffer for testing
|
||||
purposes only)
|
||||
* Added fixed precision math support
|
||||
* Added some color converson routines into what may become a real graphics library someday.
|
||||
* Added a framebuffer driver for the DM320 (untested on initial check-in)
|
||||
* Network: add support for outgoing multicast addresses
|
||||
* Added some rasterizers to the graphics library

|

* Add an X11-based simulated framebuffer driver
|
||||
* The simulated target now has an option (CONFIG_SIM_WALLTIME) that will let the simulation
|
||||
run in more-or-less realtime.
|
||||
* Added more more extensive window support: frames, toolbars, etc.
|
||||
* Added support for bitmap fonts
|
||||
