I purchased a Canon SX210 IS from ebay for the specific purpose of aerial balloon mapping - decided to go with Canon due to the CHDK intervalometer capability. There is only one CHDK version for this model and my camera seems to meet all the requirements
Canon PowerShot SX210 IS P-ID: 31F6 NT D
had to use the "vers.req" file method.
The platform ID indicates DRYOS 2.3, release #0043, 2010,
and I'm using a 4gb SDHC class 6 card setup to boot.
I've tried both sx210is-100c-1.2.0-3244-full_ALPHA.zip
and sx210is-100c-1.3.0-3249-full_ALPHA.zip builds
There are plenty of example videos that indicate at this camera works with intervalometer scripts but I am unable to get any to work. The test scripts all seem to work except for ones that control the shutter. I've used a number of examples including the default script in the CHDK build but nothing seems to work. In addition the motion detection script works but only one time. The intervalometer scripts are kinda the same way, they do work once and it then shows it sequencing on the overlay but no shutter noise or pictures. I've tried all the easy stuff - any ideas?
