Spent hours trying to figure this out - maybe it will save someone some time. I'm using Osculator to route a Wacom tablet into a macbook. The real secret is that you have to have the caps locked to set up osculator, and to run the program on pure data.

there's a slight mistake in the annotation - it's the x and y tilt that isn't recognized - the x and y axis will both need to be scaled, as they are teeny numbers

Hi,

I'm a linux user, but recently I bought a MacBook Pro.
I intend to use a Wacon Tablet in PureData/MacOS; I observed cases using Wacon with [linuxevent] or [HID] objects, but but I saw :
-(http://at.or.at/hans/pd/hid.html)
-(http://puredata.hurleur.com/sujet-1442-anyone-still-working-wacom-mac-support)

that in MacOS is a little "problematic"

They know if somebody already obtained to implement?
if not, it will not be that to compile the code source it would decide?

Thanks

Hi,

I'm working on an Ableton Live controller patch in Pd. It will be used with an external graphic tablet from Wacom.

I'd like to use Pd to make "mutes" possible.
Normally i use a MIDI Keyboard and convert every Note Off message to an On message. So whenever i press a key the mute gets toggled to "off" and then when i release the mute gets toggled twice.

By now i am using "bang" objects. But they lack in the feature that they are just sending one bang message when they get pressed. I tried to something with "select" or "spigot" but these solutions aren't very good.

Does anybody know how to implement a button which sends two messages? (One when getting pressed, one when released)

Thanks in advance,
Zettt

Wecome Mason,

Does the patch you are trying to load produce any errors? You will see these in the console window or you can find them by searching for Find->Last Error

Pd files can live anywhere, but one should endeavour to maintain a disciplined directory structure.

Files that rely on abstractions living the same directory should be opened from that directory. Otherwise put all your abstractions in an "abstractions" folder and add it to your search path.

Well, I got a reply from the developer of the linuxwacom drivers when I asked these same questions...

"Once your activated wacom device in xorg.conf, wacom X driver, wacom_dev.so will take control of the dvice, that is no other program will be able to get the raw data any more."

Ok, so the behavior I'm seeing is absolutely normal, and my tablet is working perfectly. Now my only problem is those errors from the hid objects, and the fact that they produce no data.

So let me see if I understand this... where do the hid objects expect to get their data from? Is this the same situation as on the Mac, where installing a wacom driver = death? I'll try to dig into the hid source code and see if I can figure it out.

Later...

Hmmm... no, I get nothing. After I first installed the linuxwacom drivers, I most certainly did, and I checked it with xxd and wacdump... loads of data.

But now I've activated the tablet devices in xorg.conf, and it's all working according to xidump (example below), but I no longer get anything from cat or xxd, or wacdump.

Deactivating the tablet in xorg.conf (i.e. commenting out all lines in the InputDevice and ServerLayout sections and restarting) doesn't make any difference... I don't get my raw events back.

Dang... I thought this was supposed to be easy!

Continuing thanks for all help.
Cheers,
Alex

What happens if you do

cat /dev/input/wacom

Do you see lots of binary data when you move the stylus?

Hi all. I'm off and running with a Pd project on my Mac, but apparently using my wacom intuos 3 tablet to its full extent is a lost cause on Mac, so I've decided to hook up a separate Linux machine to gather and send tablet data.

I've converted my evil Dell XP laptop to a sexy dual-boot Ubuntu Gutsy machine, my tablet is all installed and working with the latest driver from linuxwacom.sf.net, and Pd-Extended looks and works great. I'm using the 0.40.3 pd-extended package (I know it's unsupported, but all the issues below are identical when using the 0.39.3 release, which I tried first, so hopefully you'll indulge me anyway .

Problem is that the tablet and Pd still won't play nice together. When I use any of the linux event objects (hid, hidio, linuxevent) to open my tablet device (/dev/input/wacom), it gets most of the way there, which I can see because lots of good info shows up in the Pd console, but no events are actually generated, and I see errors in the terminal window from which I launched Pd:

evdev EVIOCGABS ioctl: Invalid argument

Can anyone help with this? I realize that this really concerns the event externals, but I'm flexible about using anything which will get the job done. If you let me know what info will help, I'll provide, and if there's any other way I can be generally helpful, let me know and I'll get right on it.

Thanks in advance,
Alex

Info which may be of use...

Here's the first line from my dmesg:
