LCD screen for your dockstar (cheap! <$5)

Hi there everybody.
Can somebody give a link for a very cheap usb frame that works for sure with lcd4linux (maybe on ebay..) cause I can't find any.

Thanks a lot for any answer :)

Can you expound on "very cheap"?

You should be able to find something here: http://tinyurl.com/45p9jtp

As I said a few posts ago, I have a Coby DP151 I'm not using that is already hacked and ready to use. $10 shipped.

Thanks a lot everybody :D

@rat
i'm in EU.. how much for italy? accept paypal? :)

Hi hackfin and all,

I just would like to say thanks for your work.

With the help of the READMEs in http://tech.section5.ch/files/dpfhack-0.1alpha.tgz and http://tech.section5.ch/files/dpf-lcd4linux.tgz and some helpful tips from this forum I was able to get my Pearl ultra-cheap AX206 DPF working without any problems on Ubuntu 10.04 first and than on my Dockstar as well.

Regards,
Heinz

@hkramski could you share the widget code fore the log output you are using?

Nothing elegant, simply:

Widget WHO0 {
    class 'Text'
    expression '/var/log/syslog'
    width linesize
    align 'C'
    Background 'cccccc'
    Foreground '191919'
}

Widget WHO1 {
    class 'Text'
    expression substr(exec('tail -n 1 /var/log/syslog', 1000), 0 * linesize, linesize)
    width linesize
    align 'L'
    Background '333333'
    Foreground 'ffffff'
}

Widget WHO2 {
    class 'Text'
    expression substr(exec('tail -n 1 /var/log/syslog', 1000), 1 * linesize, linesize)
    width linesize
    align 'L'
    Background '333333'
    Foreground 'ffffff'
}

Widget WHO3 {
    class 'Text'
    expression substr(exec('tail -n 1 /var/log/syslog', 1000), 2 * linesize, linesize)
     width linesize
    align 'L'
    Background '333333'
    Foreground 'ffffff'
}

Widget WHO4 {
    class 'Text'
    expression substr(exec('tail -n 1 /var/log/syslog', 1000), 3 * linesize, linesize)
    width linesize
    align 'L'
    Background '333333'
    Foreground 'ffffff'
}

Widget WHO5 {
    class 'Text'
    expression substr(exec('tail -n 1 /var/log/syslog', 1000), 4 * linesize, linesize)
    width linesize
    align 'L'
    Background '333333'
    Foreground 'ffffff'
}

# [...]

Layout mylayout {
    # [...]
    Row14.Col02 'WHO0'
    Row15.Col02 'WHO1'
    Row16.Col02 'WHO2'
    Row17.Col02 'WHO3'
    Row18.Col02 'WHO4'
    Row19.Col02 'WHO5'
    # [...]
}

Layout 'mylayout'

Variables {
    tick 500
    tack 200
    minute 60000
    linesize 51
}

If someone knows how to pull the line from syslog only once and use that value in multiple widget definitions, please let me know.

I also need help in configuring lcd4linux to support images on an AX206. Right now, the image class is not supported. (After all it's a *picture* frame!).

Heinz

Edit: fixed off by one leftover from "cut".

Hi Heinz,

I think you should have libgd (Ubuntu: libgd2-noxpm-dev) installed to make configure add the image widget code to the Makefile.
For displaying multiple lines from a file, I guess it would be more elegant to write an extra plugin, but I haven't gotten to that yet, still fiddling with AX206 firmware in that little free time left.

I'm quite happy now with my grown lcd4linux.conf (which I use on Ubuntu and on my Dockstar with only to comments changed). I think I share it here again, just for inspirations. Thanks again for pointing me towards these nice little DPF's and lcd4linux.

Regards
Heinz

Edit: Updated lcd4linux.conf



Edited 1 time(s). Last edit at 03/21/2011 04:57PM by hkramski.

I am working on the syslog thing. exec is not desirable, as it spwans child processes. What is nedded is a tail and head plugin with line/byte limits as well as a multiline widget, or a string plugin extension that can cut a string with a virtual line width in mind so one can use a number of single line plugins but still get proper line wrapping. I plan on working on that.

I did compile lcd4linux with the libgd2-noxpm-dev and lo and behold, image backgrounds do work :)

Also, for you heinz: diskstats works with a regular expression (hence the sd.), but the diskstats cover partitions as well as the main hdd, leading to double counting. the correct term to avoid this is 'sda$', or 'sd[a-z]$' to count over all hdds. the example provided by lcd4linux is incorrect.

Unrelated:
Anyone also getting stuff like "Mar 21 21:08:57 little user.warn kernel: [6204009.646723] usb 1-1.3: usbfs: process 16970 (lcd4linux.2) did not claim interface 0 before use" when starting lcd4linux?

I also get this warning every time lcd4linux starts.

For a preliminary exec optimization: Can't we use the timer widget to only read a long line once and put it in a (global) variable? The manual says "Timer widgets are special widgets that do nothing except being called at a regular basis. [...] the result is discarded. But you can set variables in this expression" but I can't find any examples for using variables like this.

Edit: Never mind, got it. See updated lcd4linux.conf above.

Hi there,

the message about the lack of "claim interface" is nothing to worry about. It just means that I've forgotten to do a usb_claim_interface(). There will be a next release of the libdpf with fixes and more functionality. If more people would second a public SVN repository, I'll set up one at google code.

Yes please svn at code google

Hi,

I've just ordered the Pearl AX206 DPF.
Has anyone made some progress in displaying images on it via lcd4linux yet? Where is the main problem?

"bastel" provides a dockstar compiled lcd4linux with image support here:
http://www.hardwareluxx.de/community/16519271-post1264.html
i did'nt test so far.

lou

@EPG: No problem with images anymore. Simply install libgd2-noxpm-dev first to enable image support, like hackfin said.

It's also handy to have the XWindow driver included so you can test your layout on a desktop machine running X. Just install libx1-dev for that purpose.

I now build lcd4linux

./configure --with-drivers='DPF,X11' --with-plugins='all,!dbus,!mpris_dbus'

which also avoids the dbus related warnings at startup.

Thanks lou and hkramski :)
I'll try it when my picframe arrives.

Any clues? I've been searching around for hours. I've got it to say "baks r ok"

Eeek! expected single match but found 2 - dont know what to do!

@Keith, modifying the following line in generate-hack.pl should allow the script to get further...

change:

die "Eeek! expected single match but found $count - dont know what to do!\n" if $count!=1;

to

print "Eeek! expected single match but found $count - dont know what to do!\n" if $count!=1;

This is slightly off topic but may be of interest to UK users. http://sites.google.com/site/repurposelinux/df3120 - a cheap Linux enabled photo frame that is hackable. A good companion for the dockstar indeed

need LCD display, but I'm not able to find the right one...

Do you still have it? Rat. I want one.

Don't know if this was already posted here. I only have limited time ATM, so I'm sorry if this is a repost. Just found this through google and it looked interesting:

Well some people might want to display something else than just some status messages. Ever thought about that?
I just thought that it was worth mentioning that now libgphoto supports the "new" frames, too. Could be useful.

Now that I have ISC DHCP, BIND9, lighttpd/PmWiki, IWatch, LLTD, Postfix, Samba, OpenSSH, MiniDLNA, Webmin, Motion and some small stuff running on my poor Dockstar, there a times when system load goes up to 5 or 6 and above.

Looks like this crashes/hangs lcd4linux 0.11.0-svn with hackfin's AX206 driver. (Maybe it's USB bus related?) Anyone else experiencing this? Any ideas?

Heinz

Hi,

we've been doing a bit of 'work' again. Well, more playing around, but anyhow: there is now a bit more elaborating HOWTO and improved scripts on getting code into yet unsupported frames, and also a new experimental release of experimental firmware (under development). It is fully functional with lcd4linux though, including new features as orientation and backlight control.

Check this out: http://tech.section5.ch/news/?p=77, download link on the bottom.

Cheers,

- hackfin

Good to see you back. I personally didn't have any time to play with my DPF and/or my dockstar for the last few weeks, so it's great timing on your part. That is, because I will have some time in about a week or two. I really look forward to trying out your new, updated hack. Looks like fun.

Thank you very much so far. Keep up the good work. ;-)

Rat (and peter) - Thank you for all your information. I made a rookie move with my shift3 and didn't backup the fwimage.bak file. Could you please post a copy of yours? I didn't make the pixel offset change and need to restore to the original firmware to flash back the updated spec file firmware.

Thank you,
HW
