-The following instructions will walk you through the steps needed to change the firmware on this camera to take picture every 20 seconds
Canon A570 IS Mods:
-The CHDK code was originally written by Rick von Glahn from Edge of Space Sciences (EOSS)
-These steps are performed with the camera modified to turn on and off with a external switch
-The steps to modify the hardware of the camera are contained in a different presentation
- 2GB can hold ~ 566 pictures
Canon A570 IS Mods:
-This mod uses CHDK to add autonomy to a digital camera without the use of a timing circuit or further modifications to the camera
-CHDK is firmware enhancement
- It only works with Canon digital cameras
-Please see the following website for much more information http://chdk.wikia.com/wiki/CHDK

Even though the card is in the “LOCKED” position it will be able to be written to via the CHDK firmware.
-Power on the camera
- If the script that runs is the Gateway 2009 script than you can skip to end of these steps
Canon A570 IS Mods:
- Insert locked SD card and make sure the camera is in “RECORD” mode
-Power on the camera
- “Default Script” and the “<ALT>” should be visible

Canon A570 IS Mods:
-When you return to the “Script” menu ensure that "Script Autostart" is checked (a dot in its selection field).
Canon A570 IS Mods:
-Also make sure the “Current script” is correct
-Now click "MENU” to save these changes to the configuration file
Canon A570 IS Mods:
-Turn off camera
-The next time the camera is turned on, it will run the script
- It will go through a series of camera setting changes which will take about 60 seconds
-Then the camera will begin to take pictures every 20 seconds until the card is full
Canon A570 IS Mods:
- 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:
-Turn on the camera
Canon A570 IS Mods:
-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
-Next press the printer button to 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:
-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
- Pictures on card should be in the JPEG format not *.RAW format
- To delete pictures, you must remove card and lock
Canon A570 IS Mods:
-You can modify your code without reloading the firmware
-For example lets change the “sleep” value to 5000
Canon A570 IS Mods:
-Power off camera
-Remove SD Card
-Unlock SD Card
-Open CHDK/Scripts/cu_gateway_fall_2009.bas
- Scroll down to end of code and change sleep = 5000
- Save
Canon A570 IS Mods:
- Remove SD card and lock
- Insert SD card into the camera and power on
-Pictures should be taken every 8 to 10 seconds now
- I would suggest a 20 second (sleep = 16000) for 135 minute flight time
Canon A570 IS Mods:
-You can also “rem” out pieces of the set up or other functions but test first
-Camera is working, it shall also be working at the end of the semester
-Take good care of this camera
-Thank you.
