The wrj4P5 is working fine for me on XP.
No problem to catch RimokonEvent events or to analyse rimokon position with rimokon.senced ... that's fine.

But I'm now trying to analyse pointing values. I'm able to catch datas (rimokon.irLights) when the sensorbar is on. But this datas are very unstable. For what I've understood, there 4 vectors value corresponding to the 4 IR sources.
The value are different but I'm able to detect a general mouvement when observing them, even if they are not at the same position (of course the IR sources are not at the same position).
The problem is that the rimokon.irLights[0] do not correspond to the first IR source, but to a different one at each initialization, and the initialization remade all the time. So I'm not able to find a stable position because most of the time 1, 2 or 3 rimokon.irLights values are set to (-1,-1).
Do anyone have a good result for this ?

some discussion was done around your trouble, see
http://processing.org/discourse/yabb_beta/YaBB.cgi?num=1186928645/45

my test with two candles seem to be good
http://www.geocities.jp/classiclll_newweb/IR_Sensor_Test/applet/index.html
with our eyes.

irLights[i] is the result of the blob detection on the WiiRemote's IR-Camera performed by Wiiremote's hardware.
so the order of irLitghts[] may be according to spot position, left-top -> right bottom on the image of the IR-Camera.
this means
1. small roll form horrizontal position will cause the index swapping.
2. lights[1] will be switched to [0] when lights[0] is out of frame.
i think what you can do is to distinct the light source by the previous position, rather than each previous indices.
(i'm thinking about the "trackedIrLights" class.)

...btw...

pls use rimokon.sensed rather than rimokon.senced.

Hi all,

what you find below is an error I get compiling a processing sketch. This sketch is used to grab the IR data coming in from the wiimote.

Unfornately I'm a newbie to processing and java, thus I really don't understand the type error.
Further below you can find the entire processig sketch
Can anyone help me out?
Thanks!

somebody knows this error¿? The problem is the wiimote¿?¿? or the version of widdcom?
The error is:
Exception in thread "Thread-3" java.lang.NoSuchMethodError: wiiremotej.WiiRemote.setIRSensorEnabled(ZI[B[B)V
at lll.wrj4P5.WiiRimokon.addTalker(WiiRimokon.java:84)

One think: Processing detects the wiimote and the signal os the buttons, but the signal of accelerometers the program does'nt recognize.

Thanks.

sorry for too late.
>Giova
your sketch seems to run well.(with IR spot size and w/o any extensions)
what your env.?(OS ver., P5 ver., JRE ver, WiiremoteJ ver, jsr082lib ver., BTStack ver. and Wrj4P5 ver.)
i think your classpath setting might be wrong, but no idea now.

>marcgalvez
i ask the same things to Giova, and put the part of your code around below.
wii=new Wrj4P5(this).connect(....);
i'm wondering the reason of being "ZI[B[B)V" on ... setIRSensorEnabled(ZI[B[B)V ...

hi marcgalvez
"NoSuchMethodError" exception may occur from the inconsistency of revisions.
what your version of wrj4p5, WiiremoteJ, jsr082, BTstack?
* both of good and bad cases, this is a valuable feedback for me.

my BTdongle and stack are following, using on both WinXP and OSX-tiger(PPC).
HAGIWARA SYS-COM / HNT-UB03 / BTW3.0 (WIDCOMM)
the stack was bundled to HNT-UB03.

hello ClasicIII,

I do exactly the same that do TM in this discourse. use bluecove 2.0.2 because i don't follow 2.0.1...
and where can i download a correct version of widcomm??

versions:

wrj4p5 - link of page 2 of this discourse post of TM
Wiiremotej - link of page 2 of this discourse post of TM
Btstack¿?¿? widcomm bluetooth 5.0.1.801
bluecove 2.0.2( this is jsr82 no¿?)

OS: win XP version 2 professional

Hello Classiclll,

first, thank you for your work, it really works well.

What I want to do is to read and write the data of the Mii's from the Wiimote. Is there a way of doing this with your library? I have seen that WiiremoteJ uses some methods of reading and writing. How can I call these methods from P5?

Any help would really be great!

Thank you.

hi tino

the functionality of reading/writing from/to Mii is supported by the class WiiRemote of the WiiremoteJ Lib.
the reason i omit this functionality is
1 less needed one for P5's sketches, and
2 avoiding the conflict between WiiremoteJ's asynchronousity and P5's implicit iteration (draw loop).
anyhow, Wrj4P5 is a wrapping class, so it is easy to give you the instance of class "WiiRemote" of WiiremoteJ lib.
is this meeting your needs?

now, my todo is
1 designing "Rod"(model of line on 3D space)
2 designing "Tag"(model of plane on 3D space)
3 designing "Ship"(model of attitude and local coordinate)
4 designing "Loc4P5"(sttatic utls. for drawing with Loc/Rod/Tag/Ship)
5 thinking about "trackedIRspots"
6 wrapping and testing the Balance Board functionality of WiiremoteJ v1.5
and
7 adding getWiiremoteJsInstance() to class Rimokon.
so please wait for some weeks.

or, you can modify the code of class "Rimokon" to get your own instance.

Hello,

I've received the same error message as Giova.

Code:

I'm trying to execute the MyFirstWii script.

Here's my my system info:

OS: Windows XP Pro, SP3
Java: JDK 1.5.0 R16
Bluetooth Stack: Blue Soleil 5.5
Bluetooth Device: Unknown, but works with Blue Soleil 5.5 and GlovePIE

And configuration:

Processing: 143 w/ Java
Loc: beta-003
wrj4P5: alpha-005
JSR82: bluecove-2.0.2.jar
WiimoteJ: v1.0

I tried using Processing 135 Without Java, but this did not work.

Any advice would be greatly appreciated. For now I'll try downgrading JSR82 and upgrading WiimoteJ till something works Tongue

hi
BlueSoleil5 doesn't support the L2CAP protocol on bluetooth.
pls try one of the following
-use widcomm instead of bluesoleil (most successful, see above reply)
-use avetana (free trial for 14days)
-use old bluesolei instead of your one
any feedback is appreciated.
tnks

*notes
alpha-004,-005 are meet to WiiremoteJ v1.2,v1.3,v1.4
alpha-001,002,003 are meet to WiiremoteJ v1.0,v1.1
and making 006 for WiiremoteJ v1.5, api change and support balance board.
