- 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
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

Even though the card is in the “LOCKED” position it will be able to be written to via the CHDK firmware.

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 5 to 6 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
- 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:
- 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:
- 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_2008.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.
