Stop USBIURT autorepeat

sdx · Post by **sdx** » Sat May 12, 2007 9:48 am

I control a camera using USB-UIRT.

I use the autorepeat to make the camera go in a direction (left, right ...).

To stop this action, I send a "Cancel" but the response time is 4 secondes, is there a way to rapidely (less than ,5 sec) stop the auto repeat on USB-UIRT ?

Thanks
Antoine

Try lowering the repeat count in the Tramit Action and therefor making the autorepeat repeat the action after a shorter time.
Is "Cancel" a different IR signal?

1. In fact Autorepeat means to me choosing "Infinite" in Repeat Count (USB-UIRT : Transmit IR configuration box), this is the only way to have a continous mouvement for my camera.

2. Cancel in another IR signal that the camera understands.

Actually you can use an empty TransmitIR action to stop an infinite transmit action.

Does the LED on the USB-UIRT also flash 4 sec after you cancelled the transmission or does it stop immediately?

"use an empty TransmitIR ", it works but the response time is nearly the same, and it generates an error :

Error in Action: "Transmit IR"
Traceback (most recent call last) (908):
File "C:\Program Files\EventGhost\plugins\USB-UIRT\__init__.py", line 188, in __call__
File "C:\Program Files\EventGhost\plugins\USB-UIRT\USB_UIRT.py", line 378, in TransmitIR
UUIRTError: Error calling UUIRTTransmitIR

2. Yes, the LED continues to flash 4 sec when sending the cancel IR signal or the blank signal.

Please copy the TransmitIR action you use and paste it here between CODE tags.

Is it whhat you expect ?

If you send it only once, is the LED going off immediately?

sdx · Post by **sdx** » Sat May 12, 2007 2:44 pm

YES (I set repeat count = 1)

To stop transmission, you have to set repeat count to "0". Then you can use an empty action. But the error with a greater repeat count is a bug that should be fixed.

I just tried your code and it really looks odd. It doesn't need 4 secs here to stop, but considerable longer then it should need.

I modified the code by hand:

Code: Select all

<?xml version="1.0" encoding="UTF-8" ?>
<EventGhost Version="974">
    <Action>
        USB_UIRT.TransmitIR(u'0000 006E 0022 0000 0155 00AA 0016 003F 0016 0015 0016 0015 0015 0015 0016 0015 0016 0015 0015 0015 0016 0040 0015 0016 0016 0040 0015 0040 0016 0015 0015 0015 0016 0015 0016 0015 0015 0015 0016 0015 0016 003F 0016 0040 0015 0040 0016 0015 0015 0015 0016 0015 0016 0015 0015 0040 0016 0015 0015 0015 0016 0015 0016 003F 0016 0040 0015 0040 0016 003F 0016 068D', 32767, 1)
    </Action>
</EventGhost>

This one seems to stop immediately but uses another repeat sequence. So please try this action and report your finding.

1. "stop transmission" Understood, thanks

2. "test the code"
Good point: It stops immmediatly
Little issue : the camera move is not continous, sometimes the camera goes moving continuously and faster but I don't understand the reason !

For me IR signals are chineese, if you can indicate me how to understand them I would appreciate very much.

I was afraid this would happen.

It seems to be a bug of the USB-UIRT. You can try to learn the code with "Force RAW-Mode learning" set. Maybe this helps.

IR codes are a quite complex domain. Your camera seems to use a kind of NEC code:
http://www.sbprojects.com/knowledge/ir/nec.htm

This code transmits a longer sequence in the beginning, that holds the actual code and a shorter repeat sequence that is the same for all buttons. What I have done above is to force the USB-UIRT to use the first code as repeat sequence and that is why your camera thinks you are pressing the button many times instead of continuous holding it down.

Should I escalate the issue to USB-UIRT ? What do you recommand ?

I will stay stupid about IR signal but it is not an issue for the time being. (My camera is Canon VC-C50)

Thanks for your help , I find EventGhost very good !

Yes, I think you can report this issue to the USB-UIRT forum. You can set a link to this thread.

The Pronto code Jon Rhees needs to try it out is:

Code: Select all

0000 006E 0022 0002 0155 00AA 0016 003F 0016 0015 0016 0015 0015 0015 0016 0015 0016 0015 0015 0015 0016 0040 0015 0016 0016 0040 0015 0040 0016 0015 0015 0015 0016 0015 0016 0015 0015 0015 0016 0015 0016 003F 0016 0040 0015 0040 0016 0015 0015 0015 0016 0015 0016 0015 0015 0040 0016 0015 0015 0015 0016 0015 0016 003F 0016 0040 0015 0040 0016 003F 0016 068D 0155 0055 0015 0E31

I think you would be better off using the camera preset positions and creating a patrol you can call with EventGhost.

I mean realistically the camera will only have a few common field of views. No matter what you do you will never be able to use a 4way on-off hardware device to track moving objects with it (what all remotes I have seen have).

You can do it with a joystick, but they aren't on/off directionally.

Do you have any presets set?
