Would there be any way to use the USB hub integrated to the circuit board on the PS3Eye to control some I/O ports out of the camera itself ? that would simplify soooo much my cabling connections as I need to control simple pulse on 4 I/O pins independantely of the camera!
Thanks

can someone help me?
]]>I keep getting this error
A call to PInvoke function ‘Prototype!Prototype.CLEyeCameraDevice::CLEyeGetCameraUUID’ has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
When i try to use the CLEyeCameraDevice.
This only happens in 4.0 applications, not in v3.5
Anyone got a clue why this is happening?
SOLUTION:
Import dll external like so
[DllImport("CLEyeMulticam.dll", CallingConvention = CallingConvention.Cdecl)]
void CaptureThread()
{
int w = 0, h = 0;
System.IntPtr Scan0 = _map;
int nVal;
CLEyeCameraGetFrameDimensions(_camera, ref w, ref h);
CLEyeCameraStart(_camera);
int i = 0;
var color=0;
unsafe
{
char* thisPtr;
char* tmpPtr;
while (_running)
{
if (CLEyeCameraGetFrame(_camera, _map, 500))
{
if (!_running) break;
Dispatcher.BeginInvoke(System.Windows.Threading.DispatcherPriority.Render, (SendOrPostCallback)delegate
{
thisPtr = (char*)Scan0;
for (int y = 0; y < h; ++y)
{
for (int x = 0; x < w; ++x)
{
if (ColorMode == CLEyeCameraColorMode.CLEYE_COLOR_PROCESSED || ColorMode == CLEyeCameraColorMode.CLEYE_COLOR_RAW)
{
tmpPtr = (thisPtr + (y * w * 4) + (x * 4));
nVal = (int)*(tmpPtr);
if (nVal < 0) nVal = 0;
if (nVal > 255) nVal = 255;
*((thisPtr + (y * w * 4) + (x * 4))) = (char)nVal;
}
else
{
tmpPtr = thisPtr + (y * w ) + x;
nVal = (int)*(thisPtr+y*w+x);
if (nVal < 0) nVal = 0;
if (nVal > 255) nVal = 255;
*(thisPtr + (y * w ) + x)=(char)nVal;
}
}
}
BitmapSource.Invalidate();
}, null);
i++;
}
}
}
I have the problem on 3 computers. The only common theme is an AMD processor… can anyone confirm this or know why exactly? Anyone at CL have this working with an AMD proc?
AMD x64 DESKTOP #1- DOESNT WORK
AMD x64 DESKTOP #2- DOESNT WORK
AMD x64 LAPTOP - DOESNT WORK
INTEL x64 DESKTOP - WORKS
INTEL x32 LAPTOP - WORKS
After some testing it looks to be an AMD processor issue for sure. Perhaps only AMD x64, not sure since I don’t have an AMD x32. All my development machines are AMD.
]]>We have been working with Python-OpenCV and PS3Eye on Linux-Ubuntu were the things work fine for multicam applications.
Now we are working in Windows 7, my code still in Python-OpenCV and with the CLEye Platform Driver we are able to work with one PS3Eye as it was expected.
Then we downloaded the CLEye Platform Driver to work with 2 PS3Eye but we didn’t figure out how to make them work, only one of them were detected by the Windows7 OS, and the CL-Eye Test under the “Devices” shows us only one PS3Eye cámera and the laptop cámera
Then we bought the CLEye Dual Pack ($20) thinking it will let the Windows7 OS detect both cameras but it doesn’t work either, the CL-Eye Test sill showing us one PS3Eye cámera and the laptop cámera
We need an advise on how to use both cameras in Python-OpenCV
Thanks in advance,
