Based on a few limitations I decided to start off down the multi-instance chdkptp route using AutoIT [
http://www.autoitscript.com/site/] as control [has a built in IDE with an easy to use GUI builder in comparison to AutoHotKey is reason, so far, for that].
Currently i'm trying to get my hands on the stdout chdkptp "list" info [to use bus/dev info with multi-instances] and having not a lot of fun with the AutoIT "StdoutRead" command. Absolutely no idea how this might scale to many dozens of cams but hope it's worth a go.
Anyway, my 1st [cam1 of 2] SX150IS has been operating as expected [based on a very limited set of expectations
] with chdk & chdkptp so, I just got the 2nd one [cam2 - ebay UK canon site refurb] out of it's box, inserted the SD card [previously extracted from cam1], powered on, ensured equivalent firmware version, ensured basic chdk operation then powered off.
Shortly after this:
- plugged usb lead [working with cam1] into cam2
- press "power on" cam2 [starts in playback]
- connect usb to PC => LCD goes black and green LED turns on => cam will not respond to any key press or mode change
Then:
- start chdkptp gui => press "Connect" and message "Error: no devices available" is displayed.
The
problem challenge is constantly repeatable. Both cams in 'P' mode. Same win7 64 bit machine used - chdkptp snapshot r438 used.
Any comment [other than "write-off"] appreciated.
