kindle directfb tutorial

[fbdev]

0) set up scratchbox (http://scratchbox.org/) cs2007q3-glibc2.5-arm6 compiler.
1) ssh into your kindle. (requires usbnetwork)
2) tar the libraries on your kindle.
# cd /mnt/us
# tar cf libs.tar /usr/lib
3) scp the /mnt/usr/libs.tar into scratchbox.
4) extract the libraries into scratchbox.
# cd /
# tar xf libs.tar
5) download the attached file and extract it into scratchbox.
6) compile main.c in scratchbox.
# gcc main.c -Iusr/include -Iusr/include/directfb -ldirectfb -lfreetype
7) scp a.out onto your kindle.
8) ssh into your kindle and run a.out.
tested on a kindle 3g (v3.1).

I cannot find directfb on DXG...

[dicalp]

I know this thread is very old but I'm curious how fast/good can directfb runs on kindle touch 5.1.2. I got the following error message. Any idea?

[root@kindle development]# ./a.out

It probably means: -ePEBCAK

When/where/with what did you compile it?
(which compiler, compiler command line, linker command line, etc)

When/where/with what did you try to run it?

Sorry, we can't see over your shoulder from here.

[dicalp]

Thanks for responding. What's -ePEBCAK btw?

Just did it.
scratchbox-toolchain-cs2007q3-glibc2.5-arm6.
just compile directfb in scratch box and link it with the tutorial attached in here with all the default settting. no magic.
scp the executable to kindle touch and run it.

Hmm...
Your detailed explanation: "Just did it"
My detailed answer: "You broke it"

- - - -

Come on now - give us a chance to help -
Copy the list of actions in the first post, and then edit in your version of each.
Mention what you skipped and/or added.

(Note: having the default binary name of a.out is not expected in a working, real-life, example.)

[dicalp]

ok .. obviously there is no free lunch. code does not work out of the box.

need to compile the libraries as so and copy everything .. including the directfb-1.2.9 directory to my kindle touch. basically the whole /usr/local/lib directory to kindle.

then add the following code into the tutorial code:
DirectFBSetOption("module-dir", "./directfb-1.2-9"); // depending on where you copy the files to.

unfortunately still not much luck ... the last repaint command gives exception.

[root@kindle development]# a.out

instead of using this tutorial ... I tried this simple tutorial ...
http://directfb.org/docs/DirectFB_Tutorials/simple.html

it works flawlessly on my kindle touch!

guess i will not be using this code anymore.

Not too surprising, since the code is for a K3 and you are trying to run it on a K5.

[twobob]

meh. dunno what you are trying to do.

but this can totally work.

Will dig some stuff up.



CAVEAT: The attached thing IS NOT A FULLY POLISHED APP FOR THE k3. The menu wont work - you wont be able to exit easily blah blah blah.... it's just a POC for this person.... feel free to fix it and make it perfect.

[root@kindle root]# ls /var/tmp/root/.directfbrc

(nothing)

[root@kindle root]# finder directfbrc     ( you don't have "finder" btw)
/etc/directfbrc
[root@kindle root]# cat /etc/directfbrc 
no-vt
linux-input-devices=/dev/input/event0,/dev/input/event1
[root@kindle root]# cp /etc/directfbrc /var/tmp/root/.directfbrc

so copy the file like I show here to run custom directfb stuff... however, chances are it will look really rubbish as the screen will misreport the size and only show half the content (well 400 px spread over 800)

however I fixed this only this morning (somehow) will make a post on it briefly before I collapse.

EDIT:
Ah.. make this...

system = fbdev
fbdev = /dev/fb0

mode = 600x800
scaled = 600x800
depth = 8
pixelformat = LUT8
no-cursor # Disable Cursor
no-init-layer = 0 # Disable Layer Initialization
no-vt # Disable vt
no-vt-switch # Don't allow vt switching (redundant?) but meh .
smooth-upscale # Scaling
smooth-downscale
window-surface-policy = systemonly # Window surface swapping policy:
desktop-buffer-mode = backsystem # Desktop buffer mode:
linux-input-devices=/dev/input/event0,/dev/input/event1

and you will get nice output.

also you will need a:

echo 1 > /proc/eink_fb/update_display

personally I wrapped that in a timeout loop in the minesweeper app itself.

gboolean refresh_screen (gpointer data)
{
  system("echo 1 > /proc/eink_fb/update_display");

  /* Return true so the function will be called again; returning false removes
   * this timeout function.
   */
  return TRUE;
}


// and then... in the "main" loop add a:

    	 /* Add a timeout to update the screen every 750 milliseconds or so */
  gint func_ref = g_timeout_add (750, refresh_screen, vbox);

https://github.com/steshaw/gtk-examp...09.minesweeper for main code...

That should work for all simple gtk apps.


I simply compiled it with the 2007q3 arm softfloat toolchain.

I REPEAT:
CAVEAT: The attached thing IS NOT A FULLY POLISHED APP FOR THE k3. The menu wont work - you wont be able to exit easily blah blah blah.... it's just a POC for this person.... feel free to fix it and make it perfect.
