Hi, all. I have a Powershot A530, and just installed CHDK on it, using my Linux laptop. All is working well, including the remote option, which is to say it does take a picture when I put the USB cable in. So now comes the time to ask for something a little fancier, and i looked through the forum to see where things are on that front.
I understand getting any further than that will take time since the USB interface into these cameras is ill documented. However, at least in Linux there is the usb_modeswitch command, which will send the camera any kind of message. So I thought I'd ask for a few details here.
1. how does CHDK deal with the USB connection?
a. Does it only detect the power line ?
b. If so, what current draw should this require?
c. If it probes for data (my laptop indicates otherwise, but it could be wrong),
has anyone tried things like just sending the camera some reset messages?
2. has anyone tried using Arduino-type assemblies to connect to CHDK? If CHDK only plays with the
USB power line, that is what it will require, and I may have the time to try it.
