Hi,
Something is terribly annoying : ARC resets its default camera so if you are using a different camera than the ezb camera, any script that is supposed to boot your cam and then start it in the camera settings will not activate the one you want.
Is there a way to select a camera in the list as default and lock it so it stops bugging me like trying to force me to buy the low res ezb camera ?
thank you.
PS : ezb v4 is full of bugs. I can't count how many I meet. It is VERY unstable. Please, provide us with a firmware at some point. It is really very annoying. few examples :
-ezb disconnects -ezb has flawed digital ports : servos and motors won't respond ezb needs to be disconnected then connected again -ezb v4 used in conjunction with ezb V3 will screw all servos mixing up the old 100 position values and the new 180 positions. ARC has a very slow response rate - often due to a wifi board that is too slow, apparently, or a flawed buffer in the software, Idk. -digital ports will all lock to ON position and turn the robot totally nut and crazy -ARC will crash, very often, as soon as more than 3 scripts run at once. -i2C port is far too unstable. and so on... can't remember all the bugs I've encountered but it is really a lot.
Lastly, the question regarding starting the camera with a specific device. That already exists.
There is a feature when editing scripts called Cheat Sheet. This is a tab which displays all available commands of any control added to ARC.
The option you are looking for is listed in the Cheat Sheet under the camera control. Here is exactly how to use it..
[feature] ControlCommand("Camera", CameraStart, [Camera URL:PORT]) [/feature]
and an example code would be
Damn! I definitely have a problem with the Cheat Sheet each time I'm looking for a new / never used before feature I just can't find it. I'm sorry about this, this is so stupid... Thanks anyway.
If it's helping, it isn't stupid
. I'm also sure a huge number of people are watching this thread and also learning
ARC is MASSIVE and it's funny - because some people say "document more", but we do, it's just that the documentation is also massive! Haha, such as the cheat sheet. The Cheat Sheet is the world's best documentation for "what you can do". The problem is that there's a lot you can do!
I always forget what commands are even possible. When you asked about the camera, i had to look to see if it was even there!
Hi,
I'm coming back to this forum because I'm still struggling with cameras. I can't get the script supposed to start the camera to actually start it because each time I used a camera, well I need to refresh the list for the camera to work again. Otherwise the start button is stuck to "stop" (as if camera was running, but it's not) and I get error messages each time I try to actually stop it.
So, in clear : most of the time I can't stop a camera to restart it while there's no more picture. It's frozen on run mode. The only way is to restart ARC.
here is the error message :
Error Initializing Camera: System.Runtime.InteropServices.COMException (0x800401E4): Invalid syntax (Exception from HRESULT: 0x800401E4 (MK_E_SYNTAX)) at System.Runtime.InteropServices.UCOMIMoniker.ParseDisplayName(UCOMIBindCtx pbc, UCOMIMoniker pmkToLeft, String pszDisplayName, Int32& pchEaten, UCOMIMoniker& ppmkOut) at Rp33miUMIGbqXYpali.lvF6UlmL50Nw9ZUXPA.scapxQaT9t(String ) at Rp33miUMIGbqXYpali.lvF6UlmL50Nw9ZUXPA..ctor(String ) at EZ_B.Camera.StartCamera(ValuePair videoCaptureDevice, Control processedPreviewControl, Control realtimePreviewControl, Int32 captureWidth, Int32 captureHeight).

Let me know if there's anything you can suggest me from there.
Thanks.
also, is there a script command to refresh the list ? That'd be useful and, I swear, this time I looked extensively into the cheat sheet!
Haha there isn't a refresh ControlCommand for the camera. That's a strange error - it's a hardware error. I can add a refresh for you. I'm wondering what that hardware error is about... Maybe the camera takes a little longer than usual to initialize? Or is the resolution unsupported?
What settings do you change to get the camera to start working? Hardware errors are nearly impossible to debug when we didn't make the hardware.
I too have this refresh necessity. If I don't refresh the list, the camera may not appear in the list, or I just can't start it without refreshing. A refresh script command would be nice, or perhaps a "refresh on load" feature could be made. I don't get an error though.
As a quick workaround, the Remote Mouse plugin can be used to automate just about anything you can do in ARC with a mouse that there isn't an existing ControlCommand for: https://synthiam.com/redirect/legacy?table=plugin&id=37
