Photo keyring as screen

@meltwater

ax206term is just a terminal console. The other ported programs can be found here. The dpf-ax SVN comes with a sample lcd4linux conf file and the build script should work too. I'll be trying lcd4linux out on my R-Pi soon. lcd4linux can certainly display images and pydpf would too.

Thanks very much! I'll have a go and see how I get on.

Thanks to some help from doozan.com I now have a hacked picture frame.

Hopefully that will also help you out. Happy to give more details if needed.

Now comes the small task of trying to work out how to use lcd4linux...

cud u plz give that ebay link to buy these kinda frames!!

Mine was from dealextreme.com, but be warned they can change stock. It works with Ax206term, yet to try the others though.

@ meltwater, ax206geek - Thanks, will check out dealextreme

This is one neat little trick. Too bad the larger photo frames tend to run off memory cards instead of direct USB transfers to internal memory. *clicks the "watch thread" button*

Going slightly off-topic here, but some Samsung frames - the larger frames can do these:

Nice work with the ax206term! Did anyone of you get the DPF working with lcd4linux on the RPi? I successfully flashed my DPF (it's the China Version, dx21334b). However, with the example config from dpf-ax, lcd4linux cannot find the DPF:

Code: Select all

$ ./lcd4linux -f ../dpf.conf -F
Found AX206 DPF
Got LCD dimensions: 0x0
dpf: cannot open dpf device usb0
Error initializing driver DPF: Exit!

My guess is that the port identifier is different on the RPi, i already tried usb, or usbdev1.4 (which is the the port reported by dmesg).

Can anyone help me? I'll try the st2205term/ax206term now, already compiling...

Best,

Max.

Shame on me... of course lcd4linux needs to run with sudo. It's working now

wonder what it would take to get them to make a raspberry shaped one:

(edited to the 1.5" display heart shaped one, more raspberry approximate already)

That one is so close, a little sharpie details and some glued on leaves and you are there.

nice idea!

funny, I cannot send PMs yet (started posting here today) -- I bought this display from eBay (Germany in my case, but it's an international seller):

http://www.ebay.de/itm/260978964426?ssP ... 1439.l2649

nice idea!

Alas, too nice/tempting. Ordered one on the off chance it's a supported model.

Hello, can explain how you installed the LCD in the RPI?

You can do a How to, what I have with the Firm_21334a of Superelchi, but when compiling in Raspberry does not work. I have the same error as above you.

I can try to help. Do you have errors with compiling lcd4linux or with permissions

Code: Select all

dpf: cannot open dpf device usb0
Error initializing driver DPF: Exit!


If it is compiling errors, just make sure the dependencies are sorted out, this is IIRC

Code: Select all

sudo apt-get install autoconf libtool libusb-dev python2.6-dev


then build-dpf-lcd4linux.sh should execute smoothly.

The permission error was solved with sudo but lcd4linux will also complain on the permissions of dpf.conf so if this is done from lcd4linux directory inside dpf-ax directory

Code: Select all

chmod g-r-x,o-r-x ../dpf.conf


should sort things out

Thank you so much

This is what I get on the console

Code: Select all

Try copying libdpf.so to /usr/local/lib. I've also uploaded my lcd4linux folder with compiled binary from my Pi to here

This is the error after installing the dependencies

Code: Select all

Code: Select all

This is the error after installing the dependencies

Assuming libdpf.so is in /usr/local/lib, try this

Code: Select all

ldconfig /usr/local/lib


Assuming libdpf.so is in /usr/local/lib, try this

Code: Select all

ldconfig /usr/local/lib


No I do not find on any side libdpf.so.

Sorry not to do more.
Thanks for your help

@gabychan

You were supposed to compile dpf-ax to obtain libdpf.so which is in the Debug folder of dpf-ax. Anyway here's my copy

Thanks,

My orders

Code: Select all

# sudo rm -rf dpf-ax
# sudo svn co https://dpf-ax.svn.sourceforge.net/svnroot/dpf-ax/trunk dpf-ax
# cd dpf-ax
# sudo cp your_libdpf.so /usr/local/lib
# sudo chmod 755 dpf.conf
# sudo ./build-dpf-lcd4linux.sh
# cd lcd4linux
# sudo make
#pi@raspberrypi:~/dpf-ax/lcd4linux$ sudo make
make  all-am
make[1]: se ingresa al directorio `/home/pi/dpf-ax/lcd4linux'

It seems that this fixed

Hello,
If it can help somebody, I already launched a subject about this in august (a long time ago ^^) :
viewtopic.php?f=46&t=428
Don't know if it may help but I had the hack working on a cheap asian NAS (so ARM hardware...).
In the last answers the subject was changing to "working lcd screens".
At least it will help google .
Should I link this topic in a reply of the previous topic ? [which should be closed then]

Gabriel
ps : I'm going to use the screen of a "coby dp-152 keychain digital photo frame" in this project : viewtopic.php?f=35&t=7739 and I will add pictures soon.
