- Sometimes the script doesn't execute properly the first time it runs.
- If this happens, let it run it's course for around a minute or so then turn the camera off then on again and it should work fine
- It should continue to work just fine on every subsequent power up
Canon A570 IS Mods:
48
-Turn on the camera
Canon A570 IS Mods:
49
-You can turn the camera off anytime.
- If you wish to stop the script during execution just press the shutter release button and that will interrupt the execution of the script
- In this way you can gain control of the camera without having to remove the card
-This is handy if you want to review photos, or do something else without the script running.
Canon A570 IS Mods:

-After the pushing the shutter, you must push the print button to have normal camera operation
Canon A570 IS Mods:
51
-Remember, any setting you might make to the camera will be restored to factory default settings next time the script runs as that is the first action the script takes
- Once you interrupt a script it must be re-run from the beginning you can not PAUSE a script and RESUME it
Canon A570 IS Mods:
52
-You can modify your code without reloading the firmware
-For example lets change the “sleep” value to 5000
Canon A570 IS Mods:
53
-Power off camera
-Remove SD Card
-Unlock SD Card
-Open CHDK/Scripts/cu_gateway_fall_2008.bas
- Scroll down to end of code and change sleep = 5000
- Save
Canon A570 IS Mods:
54
- Remove SD card and lock
- Insert SD card into the camera and power on
-Pictures should be taken every 8 to 10 seconds now

55
-You can also “rem” out pieces of the set up or other functions but test first
