PowerShot 300HS remote and script ?

how can i ger the remote to run a script?
 
I would like to start a HDR script usen the remote.
 i have been at it for days now and no luck.
all i can do is get the remote to just do a SIMPLE shoot.
and to me thats just a wast of time...........

i was working with "something" like this...
but all it does is click on forever.
I want it to start with the remote
it will take the 3 shots and then STOP
and then Wait for me to hit the remote button again to take the Next 3 shots.



@title High Dynamic Range

:loop
wait_click 1
is_key k "remote"
if k=1 then print "1) normal"
shoot

set_aflock 1
get_av96 p
get_sv96 s
get_tv96 t

print "2) bright"
set_tv96_direct t-192
set_sv96 s
set_av96 p
shoot

print "3) dark"
set_tv96_direct t+192
set_sv96 s
set_av96 p
shoot
     
set_aflock 0
print "...done"

goto "loop"
end

You need to amend your logic to something like this. The key is you need two nested loops - an outer one that repeats everytime the remote is pressed and an inner one that waits for the press.

Code: [Select]
while 1
   do
       sleep 10
       a = get_usb_power
   until a > 0
   print "1) normal"
   shoot

   set_aflock 1
   get_av96 p
   get_sv96 s
   get_tv96 t

   print "2) bright"
   set_tv96_direct t-192
   set_sv96 s
   set_av96 p
   shoot

   print "3) dark"
   set_tv96_direct t+192
   set_sv96 s
   set_av96 p
   shoot
     
   set_aflock 0
   print "...done"
wend

With the current CHDK stable release,  you need to do something like the script zeno posted above.  With the development version of CHDK,  there is an option to let pressing the USB remote start the currently loaded script.  In CHDK-DE,  this happens automatically, there is no option.

So it just depends on which version of CHDK you are using.

So the script posted by zeno is your only option.

it works the first time ...
but after the 3 shots i hit the usb button again i get (Parse err)

 :(
Add a line with the single word End at the bottom of the file ( as the last line ) and then make sure there is a blank line or two after it ?

Also, please cut and paste the exact script you are now using here.  Use the Insert Code function in the edit tools (the button with the # sign) if at all possible ?

What messages do you see on the screen while the script is running ?

i'm a CHDK noob and have been floundering around trying to figure it out.
  • is there a 300HS HDR script?
  • you mentioned a 300HS remote shutter release?
  • can you point me to the 300HS scripts?
  • is there a way to auto boot into CHDK instead of changing the firmware every time or is there a reason not to auto boot?
  • i turned on superfine JPG compression - why does the compressed bits/pixel show 5 @ superfine and 3@ normal large?  the superfine file size is about 3 times as large and the normal large JPG setting as i would expect
thx!

Scripts are pretty much common to all cameras.  There is nothing specific to the 300HS.  Search the CHDK wiki for HDR.  Or take a look at the simple HDR script already included in the CHDK/SCRIPTS directory on your SD card

Again,  the USB remote support in CHDK is not camera specific.  Here's a good place to start : http://chdk.wikia.com/wiki/USB_Remote_Cable

<see comments above>
