im looking to put together a time lapse of a building going up across the street from my office.  i would like to take a few pictures a day, but i dont need it shooting at night.  is it possible to tell my camera to shoot at specific times of the day, every day?

Yes, you can use command get_time to check the current time. Merge this with the if and put in a loop to take a photo at exact time of the day.

http://chdk.wikia.com/wiki/Script_commands#get_time

Idea is:

1. begin a loop
2. check the time
3. if the time has come - take a shoot
4. back to 1.

You probably could have posted this http://chdk.setepontos.com/index.php?topic=8095.0;topicseen#msg85235 here rather than creating another forum thread.


Here you go :

Code: [Select]
@title DailyInteval

if get_mode = 0 then goto "in_rec"
  sleep 1000
  set_record 1
:wait_rec
  sleep 100
  if get_mode <> 0 then goto "wait_rec"
:in_rec

  print "recording started..."
:loop
   m=get_time 1
   if m=0 then
      h=get_time 2
      print "time check :",h;":00"
      if h=7 then shoot
      if h=12 then shoot
      if h=17 then shoot
      sleep 90000
   endif
   sleep 1000
   goto "loop"
end

You probably want to setup CHDK to run this automatically on startup.
