Turn an older (low spec) Tablet PC into a DIY Cintiq style digitizer for use with your Windows PC.

Written by 

A cheap Cintiq style graphics tablet from a pen based Tablet PC.

 

I recently stumbled across a few Fujtisu stylistic ST4110 'penabled' tablets on ebay. These are old pentium 3 tablet PCs with wacom digitisers. 10 years ago these retailed for over £1000 so I couldn't resist the auction as they were so cheap. Trouble was I didn't really have a use for them, I was thinking of turning them into touchscreen jukeboxes, not realising that they required the pens to function (unlike some other older Styltistics I've seen, which work with a finger).

I then hit upon the idea of using the tablet interface as an input device for a faster PC.

The wacom digitisers are serial based so it seemed trivial to send the output over the network to a modern PC. It then struck I might be able to use a VNC server/client to send the display back out to the tablet.

Although I have only tested this with the Fujtisu tablets, I don't see why it should not work with any tablet sporting a Wacom digitizer on a serial port.

I have created a linux distro using the fabulous lightweight SliTaz GNU Linux to bundle all this up. The following bits of software are used. (The client in this example is running Windows 7 x64, though any modern windows flavour should work).

Features

  • Pressure sensitive (because these digitisers are pressure sensitive)
  • Works over WiFi (a wireless digitiser, oh yes YMMV)
  • Runs entirely in RAM (so no disks to worry about messing up once it's booted, saves power too).
  • Will announce its hostname to windows networks using the NMBD portion of the samba suite.
  • Screen scaling on the client (e.g. a 1280x1024 resolution get scaled to fit the tablet screen).

For the client

HW VSP3 - Virtual Serial Port - A virtual network serial port. Free for private use. There are some open source solutions around but this is really easy to use.

The USB to serial version of Wacom ISD driver - There is some slight slight hacking required especially for x64 bit windows.

TightVNC for Windows - A VNC server implementation for windows.

Launcher batch file - to simplify connecting to the tablet.

For the tablet

Tablet Digitizer distro - A 'live' .ISO based on Linux Slitaz. Burn this to a CD to get going and then install as per instructions below.

Tablet installation

Burn the ISO to a CD. If you don't have a CD drive (or docking station) for the tablet you might be able to PXE boot the ISO and somehow loopback mount the ISO image to install.

Once booted you need to ssh (use putty for windows) in to the tablet to start the installer. You should be able to refer to the tablet by it's name 'graphtablet', or by the IP address displayed on the tablet.

Login with the credentials 'root' and password 'root'.

NB: THIS WILL DESTROY ANY DATA ON YOUR TABLET'S HARDDISK.

Stage 5 Cleaning up
Hopefully that all went well.
You can edit /mnt/network.conf to setup your network including wireless
You can edit /mnt/hostname to set the hostname
Type reboot to restart.

 

The commands you need to enter are printed in red.

Next if you want wireless support (and you have a wifi card that is supported out of the box) you can edit the /mnt/netconf.conf file. I found wi-fi to be quick enough on my setup. YMMV.

# /etc/network.conf: SliTaz system wide networking configuration.
# Config file used by: /etc/init.d/network.sh
#
# Set default interface.

# Wifi key type can be 'wpa' 'none' or 'wep'. Most people will use WPA for WPSK etc.
WIFI_KEY_TYPE="wpa"
WPA_DRIVER=""
WIFI_CHANNEL=""
WIFI_IWCONFIG_ARGS=""

The portions that need modifying are in most cases are in red. You can also edit the hostname of the device by editing /mnt/hostname. The system implements the NMBD portion of the samba suite and so should announce itself your local windows subnet for name resolution.

Reboot the tablet off of the Harddisk.

Client Setup

The client in this case is a windows PC running Windows 7.

1) Install HW VSP3 - Virtual Serial Port software and configure it using the HW Virtual Serial Port icon. The settings should look like this:-

And on the Settings Tab:-

Click the Save Settings to INI file. Go back to the 'Virtual Serial Port' tab and click connect.

2) Install the The USB to serial version of Wacom ISD driver tablet. The driver requires a little hacking to get working and some additional hacking to get it working of x64 bit windows.

2a) Extract the driver to a folder. Enter the extracted folder and then enter the System32 folder. Rename the file ISDCom.dat to isdoem.dat

2b) Edit the isdoem.dat file and change the line

STEP01=RegValueString;SOFTWARE\\WACOM\\ISDPort;ISDPortName;COM1

to
STEP01=RegValueString;SOFTWARE\\WACOM\\ISDPort;ISDPortName;COM3

If your on 32bit windows you can go ahead and install the driver. If your on 64 bit windows you need to do a bit more:-

3c) (For x64 windows only) In the root of the driver folder edit the file Common.dat. Delete the entire section marked [Service64]. Copy the entire section marked [Service] and paste it below. Change the section of the duplicated [Service] to [Service64]. The file should now read something like:-

#Common.dat
[PlatformData]
SERVICEBASENT=\\SYSTEM\\CurrentControlSet\\Services\\TabletService\\PARAMETERS
SERVICEBASE9X=\\Software\\Tablet
SERVICEBASETE=\\SYSTEM\\CurrentControlSet\\Services\\TabletService\\PARAMETERS

STEP11=DONE

[AddEraseData]
STEP01=Command;!EraseData!;.\\System32\\Eraser.dat
STEP02=DONE


With the altered pieces in red.

NB: This little kludge should also help out those people having trouble getting their older serial wacom tablets to work with USB to serial RS232 adapters on x64. Use at your own risk and note that un-installation might have to be done manually.

4) Go ahead and run the setup file. Assuming the tablet is running and all went well you should now be able to control the screen with the pen on the tablet.

5) Setting up the viewer. Install TightVNC.

6) The tablet is running a listening VNC viewer so we need to get our main PC to connect to this. In order to simplify connecting to the tablet we will make a copy of the TightVNC executable so we can kill it easily without affecting other running instances. Go to the Program Files\TightVNC folder and make a duplicate of the tvnserver.exe file in the same folder. Rename the duplicate tablet_tnvserver.exe.

7) Copy the Launcher batch file into the Program Files\TightVNC folder. Make a shortcut to the batch file for easy launching.

Launch the batch file via the shortcut and if all is well you should see you screen appear on the tablet.

Thanks to:-

SliTaz for a really cool lightweight customisable linux distro.
HW Group for the excellent, feature full and easy to use serial port software.

Notes:-

Your comments, suggestions and questions are very welcome. I have only had the ST4110 tablet to work with but I can't see why this would not work with any pen-based tablet that uses a serial port and has a Wacom digitizer. The linux ISO contains drivers for the Intel i830 graphics (which were a PITA on this particular tablet, hence the 3.7.0 rc5 kernel which incorporated patches to make the card work on this particular hardware). It also contains a VESA driver. I'd love to hear from anyone who has this working on a different model of tablet.

 

There is a growing discussion on this project going on in the forums at tabletpcreview.com.

Update

Ersatz Haderach at has expanded (and simplfied) on this process and made it more generic using Ubuntu. See his article here (link broken as of 06/04/2016).

    Hello!
    First of all, congratulations for your great job! I've searching for something like this for months... i had already given up until a friend of mine warned me about your project. :)

    So, is it possible to link tablet to a mac os x machine?

    Once again, congratulations.

    Kinggeek,
    If you're able to come back to tabletpcreview, we have a number of people there attempting this, but all of them seem to run into the same final problems- stuck cursor, and comparative screen res problems. We would love your expertise, and there's actually quite a lot of traffic there. I feel like we're __really__ close to figuring this out so others can use it, who have various screen res's.

    Report
  • Comment Link KingGeek Sunday, 20 January 2013 19:41 posted by KingGeek

    I think the resolution problems relate to aspect ratio. As long as the aspect ratios are the same it should work. Most of the tablets will be 4:3 aspect ration whereas a lot of modern monitors are 16:9.

    How about temporarily setting the the main PCs res to a 4:3 resolution if your tablet is 4:3 or 6:9 if 6:9 or 5:4 if 5:4 etc.

    As far as the stuck cursor goes try the driver download in the comments. If anyone would care to repost the ready rolled driver that would be cool.

    As for making it work on OSX I wouldn't really know where to start there.

    It works when you have a monitor with resolution higher then your tablet's res (like 2:1), but shows black borders around the screen when it's 1:2.

    I still can't figure out if this is possible to stretch 1360x768 image of desktop to my tablet's 1400x1050 fullscreen. Looks like this problem causes the cursor bug.

    That's it! I got my 1360x768 desktop stretched onto tablet's fullscreen 1400x1050. Just added -listen 0 to /root/.config/openbox/autostart.sh

    Many thanks to Karl J. Runge, the developer of x11vnc who led me to this fix.

    Unfortunately my mouse pointer still bugged even with full res stretched (maybe stretched res doesn't affect it?).
    Calibration doesn't fix it.

    P.S. The fix below is only for those who use live USB boot.
    1.Boot USB and connect tablet to LAN,open the COM
    2.Using Putty type:
    killall Xorg
    vi /root/config/.openbox/autostart.sh
    3.It will open autostart.sh for editing. Use down arrow key to find vncviewer line. Then press "I" on your keyboard, this enables edit mode. Using left/right arrows add "0" after -listen and your desired resolution after -scale. For example:
    vncviewer -listen 0 -scale 1400x1050 -fullscreen -16bpp -nobs -graball &
    Now, press Esc, then type :w and :q (saving and exit)
    4. Finally, type
    startx
    5. Start VNC session with the .bat file.

    I have a Le1700 with win 8. I created a new partition, booted the Iso from a Usb stick, connected via SSH the laptop with my Pc...

    everything is working fine, but when installing, what should i type here: root@graphtablet:~# mount /dev/cdrom
    root@graphtablet:~# cd /media/cdrom/

    Hi all,
    Just discovered this post and I was thinking about the delay when drawing?

    Because when I use vnc to connect from windows to my linux distro as example, I have a short but I notice a delay so the same probably applys when you draw.

    Can anyone confirm if we got a delay or not at all?

    hi!

    I'm trying to do this with my toshiba portege m200, since 3 days...(noob with linux) After searching a way to boot (no cd player, no usb boot, only sd card reader with floppy img), i finally succeed with a live slitaz img, but when I boot from a USB mounted with unetbootwin, I just a black screen.
    And of course no network from my windows to ssh, can't use IP and hostname don't work.

    So, I try a different way by using other live linux to try to install manually, I "burn" an sd card, have troubles with an old key, finally I succeed to boot and begin to learn to use the bash window.

    Trying to dual boot with a new partition, I finally erase all my partition by using the step of install.sh (with appropriate hda number of the ex-new partition created, I always don't understand why it didn't work).

    No problem, there is no important data on this computer, I continue to follow manually the script (and learn with bash), succeed, boot well, BUT
    Ip adress: No adress
    interface: null
    Default gateway: null

    Ok, ok, i check every files for ethernet network, try fix IP, searching why my eth0 have no ipv4 (but an ipv6) address (don't fix it yet), search packages for Slitaz and my intel , try to install the intel driver (forget it), learn that there is the ?module? ( dmesg | grep eth0) already (http://forum.slitaz.org/topic/cant-connect-internet-intelr-pro100-ve-network-connection). I resume, but i spend to much time to found a way to just connect slitaz to windows 7 and finally searching if i can use another version of linux (much appropriate for a novice and much network-easy), but again found nothing on tablet-pc-review.

    This is the story, I don't wan't to have a bad end, but since 3 days working on, you are my last chance!

    3 questions:
    -Is it possible to use another linux version, like crunbank(to try toconnect the network)? or you do a very special cook with slitaz?
    -An idea for my network trouble? (no ipnet (ipv4) on eth0, no ping with fix IP, interface (null), default gate way (null), network.conf well configure) and nothing with the windows side of course.
    -Is the modification running really with the resolution 1400*1050? i read somwhere that the wacom driver is blocked to 1024*768

    Here spec of the m200: http://www.freewebs.com/duckzland/m200.html

    ps: really, you can't declare that i don't google or try by myself! :D

    sorry for my frenglish

    Quite an adventure your having there.

    >>1) -Is it possible to use another linux version, like crunbank(to try toconnect the network)? or you do a very special cook with slitaz?

    I just used slitaz because it was very small and lightweight. No reason you can't use any distro you like.

    It sounds to me like Slitaz does not have the network drivers you require. You might try a new Slitaz version and see if that works then splice my scripts etc onto the new version.

    >>2) Is the modification running really with the resolution 1400*1050? i read somwhere that the wacom driver is blocked to 1024*768

    The actual screen resolution has nothing to do with what the tablet is doing (it is much higher res than the screen). What does seem to matter is that the aspect ratios are the same.

    Just a side note: Putty is great SSH client for windows that you can connect to the tablet with once you have networking functional.

    Thank you for your quick response, I try with slitaz 4.0, network is OK, but I was unable to use the remote desktop with several vnc packages, and the pen is not recognize on slitaz. I feel like unarmed with slitaz, you think you have something on your PC but in fact, each time you try something, you have to add a package and all dependent packages (and finally it doesn't work either for me), linux is making me crazy! Do you have a list of all the packages you install? I'll try in parallel with Debian distro...


    ps: previsouly I spoke of crunbank, It's crunchbang :p

    Hi,

    Sorry for the delay. I'm getting deluged with spam here and am very busy. Really this whole thing is a proof of concept. I'm sure there are a thousand better ways of doing this.

    The packages required are (from my notes):-

    ser2net-2.7 (which I think needed building in the cooker - unfortunately I can't find the package I built or I would post it).

    (http://ser2net.sourceforge.net/)

    Also I seem to have used a newer kernel:-

    linux-slitaz-3.7.0-rc5 - though I think this might have been an issue with the particular graphics card I was using.

    You might be better off using a 'normal' distro e.g. debian. I was only using Slitaz due to the ancient hardware I was using and it's fast boot times.

    Hi there!

    Yes, an adventure, it's the word I was thinking when I tip the precedent message :p. But it's always an adventure:

    I try slitaz 4 : network ok, don't try vncviewer, but no stylus response on slitaz, and also with the principal computer, is the responsiveness obligatory on slitaz to work with, as a cintiq? (I continue to try with the idea than yes, the distro need to recognize the wacom hardware to "send" the information via HW serial port)

    I try crunchbang (more friendly for an windows user like me): network ok, vncviewer don't work first, after changing the server port to 5900 (instead of 5901) it miraculously with a good framerate after changing the "screen polling cycle" to 50 ms. Stylus work, but no graphical package to run a wacom parameters window, I need to surcharge the distro with gnome and a lot of packages to run a graphical manager. I try to connect HW serial port, "lan error", I force the port 7000 (nc -lvp 7000) to listen on crunchbang, no lan error but the install of the wacom driver blocked at ~25%... (what the ***** pinguin want from me? :p)

    Finally I try debian (windows-user friendly too), network not ok first but after install of a firmware non-free and change parameters "managed=true" in /etc/NetworkManager/NetworkManager.conf., it is ok.
    Using tightvncviewer package improve greatly the framerate than the original remote viewer of debian. The stylus work, there is a wacom manager window but I can't calibrate the screen, and the test with the gimp (include in Debian DVD) shows that the pressure don't work (oh god... -_-, anyway I continue the install). Same trouble than the distro crunchbang with HW serial port and the wacom driver. But I learned that all port are opened in linux (so don't care of firewall), and that a port need to be used with a program to listening and I don't understand which program do that on the cintiq-like. Then I read again this page and stop on "Will announce its hostname to windows networks using the NMBD portion of the samba suite.", is that? the mystery of the chocolate key(linked to a french song)? I install the samba package and a gnome-friendly-windows-like-manager and... (if you are a samba-user you certainly know the next), don't work! 50 parameters lines broke all my dreams of networking the two most time-eater OS of all universe! Before spending time on forum to learn how to param samba (the crazy dance of the geek), I prefer to refer to you (king geek and power-linux-users).

    So:
    is the stylus (moves, buttons and pressure) recognition in linux necessary to work as a cintiq like device?

    who use the port 7000 in linux?

    how to parameter samba? (if it is necessary)

    maybe i must return to the digitizer distro and try to install the good package for my intel pro 100 ethernet card...

    ps: only good news: I resurrect my "burned" SD card with a low level format software ;)

    You don't want the wacom digitizer to be recognised AT ALL on linux.

    The wacom tablet digitizer will be on a serial port in linux chucking out a whole bunch of codes. The idea is to relay this data untouched to the Windows PC.

    All you need to do is get a linux distro setup with VNC working in X (which is sounds like you have done) and install ser2net to send the serial port to Windows.

    NMDB is only a convenience so you can refer to the tablet by Microsoft network name rather than IP address.

    Samba is not necessary at all.

    Port 7000 is port that ser2net is listening on for a connection from the Windows HW VSP3 program.

    OK, It run good, thank you!

    To resume for the special case of the M200 portege:
    to install linux, you need (with a windows PC):
    -sd card formated with http://ashleyangell.com/wp-content/uploads/2011/06/Toshiba-SD-Format-Utility.zip
    -sd card compiled with the tool (ignore error on WIN7) http://ashleyangell.com/wp-content/uploads/2011/06/Toshiba-SD-Memory-Boot-Utility.zip and with "core" to mount with the previous tool http://mirror.slitaz.org/boot/floppy-grub4dos
    -boot from the SD card, now you can boot from a USB stick (no possibility to install from the sd port, it's just for a floppy image boot)
    -to make your usb stick bootable, you need to download linux distro iso image you wan't and mount it on the stick with the unetbootin application
    -you certainly will have troubles with the network cards, found the packages adapted for the wireless and the ethernet (depends of the distro)

    For the Cintiq like installation use these 2 internet pages :
    http://www.ersatzhaderach.com/blog/2013/02/02/turn-an-old-penabled-tablet-pc-into-a-networkable-art-tablet/
    and this page (http://kinggeek.co.uk/projects/item/27-diytablet/27-diytablet?start=40)
    notes:
    -maybe you have to uninstall the wacom support on the distro installed, if you don't, there certainly will have lags (I test)
    -my digitizer is on the ttyS0 (ttyS=equivalent of port COM on linux), don't forget to search yours and change the value in the ser2net config file
    -I use parameter ser2net more simply (I don't know why I try different, but it works, if you have skills with the ser2net options tell us if they are usefull please :)): 7000:raw:0:/dev/ttyS0:19200 NONE 1STOPBIT 8DATABITS
    -for networks troubles with win7 use fixed IPV4
    -I can't use simultaneously the ethernet and the wifi connected to a hotspot (don't ask why)
    - I use SSNET package on debian to have good framerate and direct options with F8, also change the value of the "screen polling cycle" in tightvnc server (on win7), I use "50 ms"

    And finally, the big difference with the first website I posted, I found the way to calibrate the screen for 1400*1050, the trouble is not with the vnc proportions, not with the wacom drivers, it's the windows integrated drivers for "tablet PC" (and uninstall the package in windows change nothing for the trouble), It use bad digitizer resolution(?) or maybe use only the resolution of my laptop.
    I found it when I have to reset the calibration with the windows tablet program (you can't do that on the wacom program "pen tablet") and when I see that all the digitizer is recognized (Ctrl + clic on About, in wacom program "pen tablet"), after trying a lot of things (change a .dat file, try to trick the calibration, change proportions and resolutions on the 2 screens), just do this: http://viziblr.com/news/2011/8/14/the-ultimate-guide-to-making-your-wacom-tablet-work-on-windo.html (begin at step 2), and you will have the calibration screen of wacom when you are in the wacom program "pen tablet" (insteed of windows calibration (tabcal.exe)), with just 2 crosses (but enough to me).

    well, let's see how to rotate the screen without half screen bug...

    Rotation bug: use nvidia drivers adapted for the GPU.
    But, if you rotate the screen of the tablet, the stylus movement are still non inverted, you have to invert the screen on the desktop too -_-, and if you calibrate now, it will not work because the digitizer is not inverted. So, calibrate with normal screen, and rotate both computer after, if you wan't to have a little offset between cursor and stylus, think "inverted" to have the good offset after rotation . _0

    I'm having trouble getting this to work with a Fujitsu T4010D. I have ser2net up and running and in the HW VSP3 program, I can see the LAN and QUEUE counters going up whenever I move the pen near the screen.

    However, the port itself always shows closed, and when I try to open the Pen Tablet control panel, it just says that "A supported tablet was not found on the system."

    Also, when I try restarting the TabletService in the Windows Services list, I can see that the port is opened in the HW VSP3 client, it cycles through a few different baud rates, then it closes it.

    Has anyone encountered this before?

    I have a problem, I use a motion computing le1600 and my tablet is not reacting to my pen (or at least the client isn't).
    Please help me I'm really sad it doesn't work

    Hia,

    Hope this page still shows some signs of life!

    So after two days of fiddling around i managed to install slitaz from a USB thumb stick onto a lenovo thinkpad x201t. It had a serial wacom digitizer on its 1280x800 px screen (16:10). My desktop screen is the same aspect ratio (1920x1200).

    VNC, HS VSP is also running well, refresh rates could be but are certainly not bad after changing VNC's refresh value.

    The problem i am experiencing lays in the driver configurations (i believe). While the aspect ratios of both screens are the same and the X*Y data are correctly forwarded to the desktop, the outer right part of the screen isn't 'active'.Here is a picture to clarify.
    https://drive.google.com/file/d/0B0XhwsA3HqQldHdEbzkwcDBpVlE/view?usp=sharing

    In the wacom driver diagnositc panel - after pressing ctrl-'About' - i see the 'x-data' value going from 0 up to +-26000. The cursor follows until xdata reaches 21200.

    After opening the tablet.dat file in my appdata/roaming/WTablet folder i see this value stated a couple of times in lines like these:
    InputExtentX 21240
    OverlapExtentX 21240

    So i tried changing these values to 26000 but unfortunately it doesn't affect it at all. The file also gets rewritten by the drivers.

    So long story short, i feel that i'm so close to having a diy cintiq.. But i have no idea how to fix this issue! Did anyone find out a way to fix this issue?

    Thanks a million,
    Daan

    Ps, the aspect ratio of the digitizer's 'active area' is 4:3 right now. y=15980 / x=21240 = 0.75

    is this still alive?
    i find it very interesting, i have an idea (also i have some hardware to support my idea)
    i have 2 sluggish compaq 2710p and rather decent desktop
    those 2710p's are now used for drawing (TvPaint to be exact, so its not really resource hungry but 1.3 u type dualcore is rather short)
    so, i was looking for this kinda solution for a long time (nice cintiq is rather pricy) but i need it with a twist
    i want both of those laptops connected, one as main screen and the other as extended (since they are rather identical it should be possible to use same pen across the screen)
    also i am willing to hardwire it if needs be, in perfect world would be cool to use simple cat5
    also i have access to server rack (oldish but still like 5x faster than both of those in one bucket)
    in reality, how hard can it be stream video one way and push inputs the other way, assuming i have all Cat5 capability at my disposal

    Well, i have all working except one BIG issue... The right side and bottom side of my tablet dont work well and its imposible to calibrate de tablet with de windows cal aplication.

    When i switch my desktop res to 1024*768, is also the tablet res, the issue still remain and i cant calibrate.

    I have triyed all ur steps and i cant fix this tablet area issue.

    One more solution - Serial Port Emulator bu Eltima (http://www.eltima.com/products/serial-port-emulator/). This type of software is capable of emulating all serial port functionality, including Baud rate, data bits, parity bits, stop bits, etc. Additionally, it allows the data flow to be controlled, emulating all signal lines (DTR / DSR / CTS / RTS / DCD / RI) and customizing pinout.
    It's not free but has a lot of features and you have 14 deys for trial.
