Change resolution on daytona borad.

Post by YongSung Yoon » Sat Feb 08, 2003 7:46 am

Guys,

I'm using QNX 6.1.0A on Daytona Board(XScale).
There is 'devg-cotulla.so' for graphics drivers.
Our daytona has 640 X 350 LCD screen.
And 'cotulla.conf' describe our screen properties like below.

I want to know how I can change screen to other resolution mode. (ex more
smaller resolution.)
Can I do it though changing contulla.conf ?
If so, is there anyone who teach me how I can ?

If not, Should I change 'devg-cotulla' driver ?
'devg-cotulla.so' is included in Xcale BSP on prebuilt binary.
Where I get the source code of 'devg-cotulla.so' ?

Any idea ?

As far as I know, the board only supports one resolution: 640x350x8.
The source to the driver is under NDA from Intel, so we are not allowed
to release it.

LCD screens, unlike monitors, do not support more than one resolution.
(Some more expensive panels support multiple resolutions by stretching
the image to the panels native resolution. Also, some high-end
graphics chips can pre-scale the image to the panels native resolution).

I assume you have the Daytona working already at 640x350...

While you can't change the resolution as such, you could reduce the size
of the image, but this would introduce black borders around the edges.

If you want to reduce the image size in this manner, let us know, and
we can provide you with more details.

Yes.
I want to reduce the screen size despite of having black borders around the
edges.
Would you teach more details to me. ex) 320 * 128 or 320 * 175 .

You should be able to do this by simply modifying the 'cotulla.conf'
file and the parameters passed to io-graphics.

If you haven't already done so you should download the specifications
on the LCD controller and the LCD.

I found the LCD specs at:
http://www.sharpsma.com/pub/productfocu ... /displays/
tft/auto/tec_specs_lq058t5drq1.pdf

The LCD controller specs can be found at the Intel website:
ftp://download.intel.com/design/pca/app ... rocessors/
manuals/278522-001.pdf


You should look in particular at the following parameters in the
conf file: elw blw efw bfw x y

A quickly modified 'cotulla.conf' file for 320x128 may look something
like:

hsw=30,elw=200,blw=240,vsw=1,efw=120,bfw=200,vsp=0,hsp=0,pcp=1,oep=0,
acb=0,pcd=2,type=1,num=0,board=0,x=320,y=128

You could then start io-graphics:

io-graphics -dldevg-cotulla.so -amode=/etc/cotulla.conf -g320x128x8

(assuming you put your cotulla.conf in /etc)

Thanks. It works.
But the color of our daytona LCD screen is something wrong when using 320 X
128 resolution.
White and yellow looks like pink or red.
Can I fix this problem by modifying 'cotulla.conf' ?
If so, could you teach me about this ?

How are you starting io-graphics?

Can you post the command line used. Also can you post the parameters
you are using in 'cotulla.conf'?

Thanks

:> :> I assume you have the Daytona working already at 640x350...
