-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

-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.
