Unreleased changes after this release are available in CVS.
|

These unreleased changes are listed <a href="#pendingchanges">here</a>.
|
||||
</p>
|
||||
<p>
|
||||
This release includes one new, important extension to the
|
||||
<a href="http://www.nuttx.org/NXGraphicsSubsystem.html">NX graphics system</a>:
|
||||
This relese includes one new port, some new drivers and some important bugfixes:
|
||||
<ul>
|
||||
<p>
|
||||
NX was develop a couple years back on hardware that supported only framebuffer
|
||||
devices, that is, video hardware with video memory directly converts the memroy
|
||||
content to video. However, most MCUs that NuttX focuses on do not support such
|
||||
video memory; rather, that typically only support LCDs via parallel or serial
|
||||
interfaces.
|
||||
<li><p>
|
||||
NuttX was ported to the Luminary/TI LM3S6965 Ethernet Evaluation Kit.
|
||||
At present, that port includes an OS test configuration and a NuttShell
|
||||
(NSH) configuration with telnet support.
|
||||
</p>
|
||||
<p>
|
||||
This release of NuttX extends NX so that now renders directly to the LCD device
|
||||
via its serial or parallel interface. No in-memory copy of the screen memory
|
||||
need be maintained so this solution should also work in MCUs with very limited
|
||||
SRAM.
|
||||
</p>
|
||||
MMC/SD and Networking support are provided but not thoroughly verified
|
||||
in this release: Current development efforts are focused on porting the
|
||||
NuttX window system (NX) to work with the Evaluation Kits OLED display.
|
||||
</p></li>
|
||||
<li><p>
|
||||
A NuttX Ethernet driver for the Microchip ENC28J60 SPI Ethernet chip is
|
||||
available in the source tree (but has not yet been fully verified because
|
||||
I haven't properly connected it to hardware yet).
|
||||
</p></li>
|
||||
<li><p>
|
||||
The Olimex STR-P711 NuttX port was extended to support the ENC28J60 and
|
||||
some new networking configurations were added. The ENC28J60 has not
|
||||
been tested on the STR-P711, however, because of hardware issues (I don't
|
||||
think the USB powered board provides enough power for the ENC28J60 and
|
||||
I don't have the right wall wart yet).
|
||||
</p></li>
|
||||
<li><p>
|
||||
Along the way, external interrupt support (XTI) was added to the STMicro
|
||||
STR-P711 port and some important bugs were fixed in the STR-P711 SPI
|
||||
driver.
|
||||
</p></li>
|
||||
<li><p>
|
||||
Corrected an important UDP reference counting error. It was not a serious
|
||||
error, but it trigger an assertion was IS a serious error.
|
||||
</p></li>
|
||||
</ul>
|
||||
</p>
|
||||
<p>
|
||||
This initial release of this feature includes the verified NX extensions plus
|
||||
a driver for the HX8347, 16-bit parallel LCD. This LCD supports 16-bit RGB
|
||||
(5:6:5).

<b>STATUS:</b>
|

This port is available in the source tree, but is still under development.

This port was released in NuttX 5.5.
|

Features are the same as with the Eagle-100 LM3S6918 described above.

The examples/ostest configuration has been successfully verified and an

NSH configuration with telnet support is available.

<b>NOTE</b>: As it is configured now, you MUST have a network connected.
|
||||
Otherwise, the NSH prompt will not come up because the Ethernet

driver is waiting for the network to come up.
