camera: canon sd780
Usb remote trigger: usb 2.0 (red and black wire only) + Eflight EFLA600
usb trigger is connected to a RC receiver (5 volts)

Dear CHDK users,

I´m new on scripts and would like some help to work out a script to be used with my usb cable trigger.

Pressing the shutter bottom with my finger, the evolometro2.bas (attached) works very well, but i´m not sure how to modify it to start and stop the script using my usb remote trigger.

I tried the example "remote1" and it works fine but i can´t figure out how to adjust the evolometro2 to work in the same manner.

Thank you for your help,

Ernest

This should do it for you. Added a few other refinements too that should help it work better for you.

Code: [Select]

@title Evolo Metro v2
@param a Interval in Sec
@default a 2

print "started - going to shoot mode"
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 "setting focus"
x=get_hyp_dist
set_focus x

print "enabling USB port"
set_config_value 121 1

while 1
  if is_pressed "remote" then
    print "shooting"
    press "shoot_half"
    sleep 800  
    press "shoot_full"
    sleep 700
    release "shoot_full"
    release "shoot_half"
    sleep a*1000
  else
    print "waiting for remote"
    sleep(1000)
  endif
wend
end
