bob_binz from raspberry pi forum reported that fw_disp_dx27893 matches this frame and here's the original firmware. How to update the list of supported frames with this information?

Atm add the CRCs given by identify.py and (optional) an url to knowndpfs.py.

Note: will change soon - knowndpfs.py will be replaced by a file to be autogenerated from infos in src/lcd/ <model>/dpfmodel.h files (working on it). These "dpfmodel.h"-files will also replace the "#if defined / #ellif defined .." spaghetti-code in src/config.h (already done, made adding contrast settings much cleaner).
So in the future all model-dependent infos will be in one place.

Hi,

I can't not flash the firmware in windows. I make a dump of the orriginal bin with AX20xDump_Tool (windows aplication), when i start the the flash tool (ProgSPI) he say's:

Please wait for checking flash ID
Flash info is CMD-9f : ID:0xef301600
Flash info is CMD-90 : ID:0xefffefff
Can't find the flash info, please add its info to flash library according to the flash ID

Can someone edit it with my ID information. That this works? Or should I really switch to linux.

FlashLib.ini
dpf_dump.bin

Added your flash (Winbond W25X32) to FlashLib.ini.
You can try the focal or focal_landscape fw. Identify.py thinks your dpf is compatible...

You are the best! Thank you very much. I can flash the firmware!! Yeaahhh

Hi there Folks....

I bought a year ago a DPF from Pearl. I've hacked it with this Guide:
http://geekparadise.de/2011/04/digitaler-bilderrahmen-von-pearl-als-statusdisplay-fur-dockstar/

It worked flawelessly with lcd4linux ...


Now it was not used for more then 8 months and I wanted to use it again in one of my new projects but with VNC enabled. So I want to use the Pearl DPF with VNC to show a X session of my dockstar on the DPF like Current playing MusicTitle and Cover with mpd (musicplayerdeamon)

Now I am a little bit confused about this.

1.) Is the VNC Feature now fully useable with my DPF ?
2.) Is there any new firmware I need to flash on my DPF to get VNC working ?
3.) Does the VNC Feature need to be configured and compiled into lcd4linux?
4.) Is it possible with current firmwares that the Background Illumination can be dimmed or turned off by lcd4linux?


Is there a up to date guide I can follow so I will get the thing up running with VNC!


Thank you in advance for clearing up these questions!


Greetings Ron!


EDIT:

Finally now after nearly 2 days of trying out , installing things, many compiling errors and so on I got the Firmwares compiled from " http://dpf-ax.svn.sourceforge.net/ " ...

God I was raging many times til now! ^^

I flashed then the PearlDisplay Landscape Mode while in Bootloader Mode and now there are many eyes looking at me! ^So the Flashing was successfull...

Now I also compiled lcd4linux and it is working and also installed tightvnc to get the PyDpf.py with my MPD Server working.


I am startig tightvnc with folowing command:
vncserver :2 -geometry 320x240 -depth 24

And after executing PyDPF.py I am getting following error:

root@soprano:/home/lcd4linuxstuff/pydpf/pydpf# python PyDPF.py
Found AX206 DPF

Can someone help me with this... I am near to completion...


And What I also wanted to ask:

Should I use the hackfin Firmwares or are there any more feature rich firmwares available for the Pearl AX206 Display?

I wanted to get the Display right into VNC Mode after bootup displaying MPD Informations. Is there a way to replace the Picture with the eyes with a self made picture? And when lcd4linux is shut down is there a way to show again this self made picture/logo again instead of showing the goodbye message from lcd4linux?

Is there also a way to change the view-mode of PyDPF while running? So e.g. when MPD is Playing it shows the MPD Informations and when MPD is not playing any Music the Display will show Time and weather or something else?

Is there also a way to control the Backlight directly over lcd4linux or do i need to set it manually to the intensity with the Buttons on the back of the DPF ?


Thank you in advance. Man. This was a real PITA to the state I got this working now. Only the PyDPF errors arent resolved now... I am really happy about any help!


Thank you!

Greetings Ron!



EDIT2:

For all of you who are struggling to get lcd4linux compiled with mpd support I am providing here a checkinstall DEB package of lcd4linux with mpd Support compiled on dockstar Debian wheezy. Maaaaan.. This was a real big fat PITA!!!!!


Think this would be really helpfull for a lot of people!


I am still struggling with the errors of PyDPF... Can someone help me? I think google had changed their API or whatever so the GET requests from the PyDPF.py script are blocked from google's site!

How can I resolve this?!

Greetings Ron

Hi superelchi!

First of all thank you very much for your fantastic job on this project.
I recently acquired an egg-shaped dpf (it looks like this http://www.jovisa.biz/images/egg%20dpf%20or%20copy.jpg ) that was succesfully flashed with the acme_1 firmware.
The only problem is that, once again, the contrast makes the screen unreadable even at maximum brightness. It's way too dark.

I tried for an entire afternoon to fix it, but alas, my asm knowledge is limited and I couldn't figure out how to do it on my own. Could you please fix this problem? You can find my original firmware here: https://www.dropbox.com/s/zucn53j7mdn8cuu/full.bin

Thank you in advance!

@djJack
Please try attached fw.

superelchi

Much better! Thank you very much! :D

Just a question: every time I try to disassemble the original firmware (1MB dump), d52 complains about the file being too big. What should I do?

Head over to ax206geeks's wiki. Have a good look at the "Reverse Engineering the firmware" part.

superelchi

Not sure I am doing this correct but when I run:
sudo python fw/restore.py src/fw_disp_coby_dp151_bw.bin -f

I get:
Found AX206 DPF (bootloader)
failed to open flash driver
Traceback (most recent call last):
File "fw/restore.py", line 33, in <module>
size = detect.detect_flash(d)
File "/home/david/notepad/dpf-ax/trunk/fw/detect.py", line 78, in detect_flash
manu, dev0, dev1 = d.probeFlash()
SystemError: 94:(ffffffff): Unknown error

I have a coby 151bw, any help is preceated =)

sudo python fw/restore.py src/fw_disp_coby_dp151_bw.bin -f

Does not work, Please try

cd fw
sudo python restore.py ../src/fw_disp_coby_dp151_bw.bin -f

Restore.py needs spilib.bin which must be in the calling directory.

superelchi

Thanks that worked and I have hacked the DPF.

Now I have another problem, does anyone have an lcd4linux ipkg with dpf driver support and mpd plugin or know where I can find a guide to build it myself?

Thanks in advance =)

Check my post(s) on page 21 of this thread for script that will do that for you.

@dms

Interesting - a new species! Unkown enclosure! Battery powered! Portrait! :-o

Please try attached fw.

superelchi

I ran the script and made a working lcd4linux package but it refuses to install because of missing libdpf. I am running this on a mips (openwrt) sustem, do I need to crosscompile libdpf for mips? If this is outside this thread I appoligise this is just the only active place I know where people are talking about this. I think I just don't understand what libdpf is, I see many versions of it ie libdpf.o libdpf.h etc. Can I just copy this to /lib ?
Sorry it this is a dumb question I am new to this.

Hi dakkara,

Can you post error message(s) that you are getting?

Thanks
Roman

Hello @superelchi,

thanks a lot for the firmware I've tried it:

Hope, you can help me with that.

I crosscompiled lcd4linux, but when I try and install I get this message

I did not realize that you are crosscompiling, the script is meant to run on ARM device (dockstar or raspberry pi).
Are you crosscompiling on PC linux machine?

I suppose if you follow script line by line you will see what it is doing and you can modify it for your environment.
The missing libdpf library and module is built during compilation of dpf-ax firmware.

Thanks, the size is now correct, but I can't read any text on the menu, because white background, and the black highlighting bar and black text display

cheers

Only the menus not working?
Does the menu highlight move correctly?
Is the splashscreen displayed correctly after reset (cocktail)?

It looks like I can display something with lcd4linux and the whole display seems to be usable.
The menu highlight moves correctly, and I can go inside the menus (counting the options in submenus, because I can't see anything there)
Even after reset there is no splashscreen, I only get black screen. After pressing menu button I see the menu. After starting lcd4linux I can see the output on the screen.

Strange. The init and blit code is very similar to the original Pearl. In fact fw_disp_delightdigi_black_portrait works on my Pearl. Splash, menu and everything.
Could you try if one of the attached Pearl fws works on your dpf?

Hello, really apprieciate your help. I've tested all of them. fw_disp_pearl.bin and fw_disp_pearl_custom.bin look very similar to what I've describe before: white screen, black highlight line. On fw_disp_pearl_custom.bin when moving around in the menu, I've got a crash with red background.

fw_disp_pearl_portrait.bin works nice (almost perfect) I see the coctail splashscreen and the menu correctly I aslo can use the screen. The only problem the screen (splashscreen, menu, and lcd4linux) is upside down (rotated by 180 degrees).

Could you somehow rotate it?

Pearl landscape and custom not working but portrait is? Mmmh...
I've just ordered one of these beasts to have a closer look.
I fear you have to live with the rotated display and/or missing menus until it arrives. Shipment may take a couple of weeks to Germany.

Hello superelchi,

strange things going on here. After you message that I have to stick either with working menus or working display. I've compiled trunk once again running the script from http://forum.doozan.com/read.php?9,2435,9321#msg-9321. Afterwards I flashed the fw_disp_delightdigi_black_portrait.bin firmware and it works nicely. I see the splashscreen (coctail), the menu, and display is working nicely.

As it looked very strange to me, I've tried to reproduce it.
I've restored original firmware, and then flashed again with fw_disp_delightdigi_black_portrait.bin. An it works.

So for everyone searching for nice frame, this ones works with linked firmware (fw_disp_delightdigi_black_portrait.bin)

Thanks once again for your help.
