* arch/arm/src/stm32 and configs/stm32f429i-disco: Correct some bad
commits that broke the LTDC display example. From Marco Krahl
(2016-04-22).
* configs/samv71-xult/vnwwm: Add a more complex NxWM configuration
to support further VNC testing (particularly of VNC keyboard and
mouse intputs). Initial configuration is not functional (2016-04-23).

quality in the remote display (since it is also 8 BPP). At 8
BPP, the remote display is correct even with both GRAPHICS and
UPDATER debug OFF -- and there is no hang!
2106-04-23: The NxImage example at apps/examplex/nximage. This was
selected because it is a very simple graphics test. Continued
testing, however, requires a more complex configuration. Hence,
the vnxwm configuration was created.
vnxwm:
This is a special configuration setup for the NxWM window manager
UnitTest. It provides an interactive windowing experience via a remote
VNC client window running on your PC. The SAMV71-XULT is connected to
the PC via Ethernet.
NOTES:
1. The NxWM window manager is a tiny window manager tailored for use
with smaller LCDs. It supports a task, a start window, and
multiple application windows with toolbars. However, to make the
best use of the visible LCD space, only one application window is
visible at at time.
The NxWM window manager can be found here:
NxWidgets/nxwm

NxWidgets/UnitTests/nxwm

2. Here is the quick summary of the build steps. These steps assume

will need to adjust all of the paths in the following accordingly:
a. Install the nxwm configuration
$ cd HOME/nuttx/tools

b. Make the build context (only)
$ cd ..
$ . ./setenv.sh
$ make context
...
NOTE: the use of the setenv.sh file is optional. All that it will
do is to adjust your PATH variable so that the build system can find
your tools. If you use it, you will most likely need to modify the
script so that it has the correct path to your tool binaries
directory.
c. Install the nxwm unit test

3. Network configuration: IP address 10.0.0.2. The is easily changed
via 'make menuconfig'. The VNC server address is 10.0.0.2:5900.
4. The default (local) framebuffer configuration is 320x240 with 8-bit
RGB color.
I had some problems at 16-bits per pixle (see STATUS below). To
select 16-bits per pixel RGB15 5:6:5
CONFIG_NX_DISABLE_8BPP=y
# CONFIG_NX_DISABLE_16BPP is not set
# CONFIG_VNCSERVER_COLORFMT_RGB8 is not set
CONFIG_VNCSERVER_COLORFMT_RGB16=y
CONFIG_EXAMPLES_NXIMAGE_BPP=16
To re-select 8-bits per pixel RGB8 3:3:2
# CONFIG_NX_DISABLE_8BPP is not set
CONFIG_NX_DISABLE_16BPP=y
CONFIG_VNCSERVER_COLORFMT_RGB8=y
# CONFIG_VNCSERVER_COLORFMT_RGB16 is not set
# CONFIG_EXAMPLES_NXIMAGE_GREYSCALE is not set
CONFIG_EXAMPLES_NXIMAGE_BPP=8
5. There are complicated interactions between VNC and the network
configuration. The CONFIG_VNCSERVER_UPDATE_BUFSIZE determines the
size of update messages. That is 1024 bytes in that configuration
(the full message with the header will be a little larger). The
MTU (CONFIG_NET_ETH_MTU) is set to 590 so that a full update will
require several packets.
Write buffering also effects network performance. This will break
up the large updates into small (196 byte) groups. When we run out
of read-ahead buffers, then partial updates may be sent causing a
loss of synchronization.
STATUS:
2106-04-23: Configuration created. See status up to this data in
the vnc configuration. That probably all applies here as well.
Only some initial testing has been performed: The configuration
does not work. No crashes or errors are reported, but the VNC
client window stays black. I have not yet dug into this.
