Class #13

- 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

- CHDK is firmware enhancement

- It only works with Canon digital cameras

Canon A570 IS Mods:

- “<ALT>” will be replaced by “<CNF>”

Canon A570 IS Mods:

Canon A570 IS Mods:

- Move the cursor down to "Make card bootable...“- Press "SET" to select this option.

Canon A570 IS Mods:

- Nothing should happen. This is OK- Power off camera.

Canon A570 IS Mods:

- Remove the SD card and slide switch to “LOCKED”

Canon A570 IS Mods:

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

- “Default Script” and the “<ALT>” should be visible

- Press the shutter button to stop script

Canon A570 IS Mods:

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 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.
