Hi, I don't understand how to have the return of a camera command with chdkptp / multicam.lua


like get_focus()


Code: [Select]
!return mc:cmdwait('get_focus()')
result:

Code: [Select]
[5]={

  status={
   status=false,
   cmd="get_focus",
   msg="unknown",
  },
  done=true,
  failed=false,
 },
}



doesn't return value about focus

In multicam, mc:cmd/mc:cmdwait accept named commands that are defined in the multicam script. That's what the 'unknown' in your example is about.

To run lua code, you have to use the call or pcall commands like
Code: [Select]
!return mc:cmdwait('call return get_focus()')
Return values from you code will be returned in the inner status member as an array.

You can see the pre-defined commands at the bottom of the multicam script, around
Code: [Select]
local function init()

Don't forget what the H stands for.
