Anyone had any luck getting anything out of irLights

i'm sorry for no test, blindfish.
because i have no sensor bar, the IRSensor is not tested.
now, i have tested with a candle, but the IRSensor test is limmited.
here is alpha-003
https://sourceforge.jp/projects/wrj4p5/files/?release_id=28807#28807

[notes]
- length of irLights[] is always 4.
- when no light is, it's value is (-1, -1, -1), in each mode.
- when IRMode'ir' is Wrj4P5.EX, it's value is (x, y, -1). (default mode)
- when IRMode'ir' is Wrj4P5.IR, it's value is (x, y, s)
*where x:0to1, y:0to1, s:size. (origin is at Left-Bottom)
- if irMode'ir' is set to be Wrj4P5.IR, any extention is not available.
- bug fixed around irLights[]
- removed : Wrj4P5(PApplet parent, boolean irMode)
- added : connect(boolean ir), connect(int n, boolean ir)
- changed : sensed value of remote is mesured by G. (002 was mesured by mks)

Cool, that has gone some way towards getting it working. I've now had values returned on irLights[0] and irLights[1], but nothing on [2] and [3]... though it looks like [0] and [1] are lights on either side of the sensor bar so they will be enough to do something useful with.

However, getting data from the lights is very inconsistent - I've tried different ways to connect:

wii = new Wrj4P5(this).connect();
wii = new Wrj4P5(this).connect(true);
wii = new Wrj4P5(this).connect(1,true, false);

But whichever I try, getting data only seems to happen very occasionally - it almost seems completely random.

isIRSensorEnabled() mostly returns false and only occasionally returns true, but even when true irLights mostly returns (-1.0,-1.0,-1.0)...

Just in case I'm making a stupid mistake here's my test code. Any suggestions greatly appreciated!

Many thanks!

Code:


import lll.wrj4P5.*;

Wrj4P5 wii;

void setup() {
    size(400, 300);
    background(0);

    wii = new Wrj4P5(this).connect();
    frameRate(30);
}

void draw() {

    if (wii.isConnecting()) return;

    background(0);
    noStroke();

    //println(wii.rimokon.isIRSensorEnabled());

    if(wii.rimokon.isIRSensorEnabled()) {

	  if(wii.rimokon.irLights[0].x != -1) {
		//println("x: " + wii.rimokon.irLights[0].x + "  y: " + wii.rimokon.irLights[0].y + "  size: " + wii.rimokon.irLights[0].z);
		fill(255,0,0);
		ellipse(wii.rimokon.irLights[0].x*width,wii.rimokon.irLights[0].y*height,10,10);

	  }

	  if(wii.rimokon.irLights[1].x != -1) {
		//println("x: " + wii.rimokon.irLights[1].x + "  y: " + wii.rimokon.irLights[1].y + "  size: " + wii.rimokon.irLights[1].z);
		fill(0,255,0);
		ellipse(wii.rimokon.irLights[1].x*width,wii.rimokon.irLights[1].y*height,10,10);

	  }


    }

}

Where is the what if the what is in why?

WiiRemote can recognize spots at most 4, so if you use two sensor bars (or 4 candles/IRLEDs), you will get 4 spots.
some applications uses 3 spots to get precise relative position and rotation, i know.

first code is BASIC mode. (extension available, but no size of spot)
Wrp4P5.EX is constant for extension use.( and IR_BASIC mode)
second code is EXTENDED mode. (with size of spot, but no extensions)
third code is EXTENDED and silent mode. (same as second code)
Wrj4P5.IR is constant for IR_EXENDED mode.

hmmm, i thought the isIREnabled() tell us the IRSensor is not disabled. but it would tell us there is no spot, i start thinking.
one more thing, the sensitivity of IRCamera in the WiiRemote is unknown. can you set the power of the sensor bar up via your wii

Code:


    if(wii.rimokon.isIRSensorEnabled()) {
            //println("x: " + wii.rimokon.irLights[0].x + "  y: " + wii.rimokon.irLights[0].y + "  size: " + wii.rimokon.irLights[0].z);
            //println("x: " + wii.rimokon.irLights[1].x + "  y: " + wii.rimokon.irLights[1].y + "  size: " + wii.rimokon.irLights[1].z);

your code is seem to be OK. woud you try without isIRSensorEnabled ?
and
because my 3DVector class "LOC" has toString() implimentation, you can write
// println(wii.rimokon.irLights[0])
instead of
// println("x: " + wii.rimokon.irLights[0].x + " y: " + wii.rimokon.irLights[0].y + " size: " + wii.rimokon.irLights[1].z);
(importing LOC may be needed)

OK... I've done some more testing.

I still have no idea why it doesn't always work, but when it does it's fine... it's just not nearly reliable enough. If I had to guess I'd say it might be something to do with the 'public WiiRemote addTalker' in WiiRimokon (line 61)... On line 67 should it be testing against the variable 'ir' or 'isIR'. I'm not yet good enough at all this to test this myself - and I could of course be completely wrong...

When it has worked I've had it register 3 lights when I get close to the sensor bar (mine is wireless and has 6 LEDs), though mostly it just registers 2 - though as I said before it's usually 2 at either end which is ideal.

I'm not too bothered about the size of the lights at the moment as it should be possible to use the distance between the lights to calculate distance between the sensor bar and the remote... though it would be interesting to see how sensitive it is to size, as this might be useful in determining the yaw of the remote.

isIREnabled seems pointless - you don't need a sensor bar to see that it returns fairly random values...

If you can fix the reliability problem that would be fantastic!

i know the sensor bar of nintendo has 5 LEDs on each end.
does your wireless one have 3 LEDs on each end
im afraid your test is performed too near distance.
because the spot is the image on the ircamera, there is a minimum distance for proper use of ir-sensor.
please check this on your sensor-bar's manual.

hi, blindfish.

i have tested the IR sensor functionality of Wrj4P5 003.
it seemed OK. see

too.

the angle of view of IR_Sensor is about 40 degree, i've heard.

Thanks for testing this further. It's definitely not anything to do with being too close: I've got the sensor bar about 2-3 metres away and when it works it works perfectly... it just doesn't work often enough Sad

I guess it could be a hardware/software issue on my machine... Though the actual connection to the remote works fine, it simply doesn't seem to be getting the IR data. I'll test you demo - if I don't have any problems with that then I'll know it's something in my code.

Many thanks!

BlueCove Ver2.0.2 (for PPC/Intel Mac OSX) released!
http://www.bluecove.org/
I have tested on PPCMac replacing my avetana, and it ran well.
so, Wrj4P5 now needs

- bluecove-2.0.2.jar (and Apple BTstack)for OSX (both PPC and Intel)
- avetanaBT.jar and BlueZ(BTstack for Linux) for Linux
- BlueCove-2.0.2.jar and WIDCOMM(BTstack for Windows) for Windows

* BlueSoleil(another BTstack for Windows) may be buggy.
* BTstack built in Windows( by MS ) does not support L2CAP protocol on Bluetooth.

2. new support of WiiGuitar

so, Wij4P5 support WiiGuitar too,
and, BlueSoleil(BTstack for windows) + BlueCove2.0.2 may be run well
* a functinality of WiiGuitar support is not tested because i have not the WiiGuitar

Anyone had any luck on windows? I'm using bluecove with bluesoleil and what I have now is a message "trying to find a wii" and nothing happens then. In my bluesoleil software I can see how it searches for a new device and finds my wiimote, but nothing changes on processing side.
I've tried different ways, but with the same result.
