I registered today at forum just to share my project and exchange info and tips with you all.First of all i need to say that everything i did so far is by gathering info from this forum and other places , so nothing is actually *my* creation , i just put them together to serve my purpose.
**Thats why cameras run chdk with patched kbd.c (Credits go to waterwingz )**
1.Is there a way to reboot or disconnect multiple cameras? I have found the command for mass-shutdown.Is something like Code: [Select]mc:cmd('call reboot()')gonna work?I tried it and somehow cameras stucked/crashed.About disconnecting multiple cameras , is a new function needed in multicam.lua i imagine?
2.I saw a thread somewhere in the forum discussing how to be possible to "name" each camera so u know that upper left is camera1 , bottom right camera2 , etc etc.
Is it possible to rename a photo when chdkptp downloads it from cli ?
3.When i press shoot and cameras are standing by for usb voltage change (for me to click the switch in other words) i noticed that shooting happens after ~10 secs if i dont click the switch.Can i change this 10secs behavior?
2.I tested a bit your files .To be honest the bcamHost.lua file only , as i prefer to run scripts from pc to the camera . I am not programming expert , or lua for that matter. But i have some common sense and i try to figure things out by comparing and analyzing them.So , i tried some commands of that file and after connect() , everything else fails.Script cannot "send" them to camera and the error is the classic "no script running".I noticed that there is no start() function on the .lua file .Shouldn't be one there to start the camera-part code execution and allow the other commands to function ?Just an observation , i might be talking nonsense here.Thanks.
3.i have read the threads about unique id numbers and stuff. I will try to see if i can come up with something at the direction reyalp suggested e.g. set some numbers/names at the serial numbers in a script and handle the camera through them.For many cameras setup , that would be a boring job to do , but i believe its a one-time job.To match up some variables to ALL serial numbers.
4.About "i will take the photo in 10 secs" annoying thing. I understand the concept you are describing. My friend was thinking something like.. shooting task in loop forever and we walk around with the switch in our hands and take the shot in whatever moment we feel like .As i understand this won't happen.So the best thing that can be done is to raise that "safe limit". I will keep it in mind and think it over and let you know..no need to make something for me at this point..not yet at least. I was also thinking of some kind of countdown timer in chdkptp gui when i press shoot to inform of the remaining time and some sound alarms too .Probably easy task with some lua programming ...
And a last thing that came up my mind right now.When i click the switch to take the shot , cameras naturally disconnect from pc...... Is there something else that i can do ?
Shooting Method : I read a lot about this phase.What to use and what not to use.We started experimenting with multicam.lua (credits to reyalp )and its commands.Syncing was working good with 2 cameras.With 8 cameras connected we had some hicups .Some cameras were losing sync by a little bit.Not more than 40-50msecs.
what shooting method is "known" to have good sync with multiple cameras?
None.It is a statistical problem.With two cameras I have found that 70% of the time the sync error is less than one msec.For 30% of the time it is tens of msec, presumably because the Canon firmware is busy with an 'important task'.So, does that mean for any shoot 19 of your cameras will have a sync error of tens of msec ?
