N800 remote control for EOS Camera !
 
1 Attachment(s)
Hi !

I followed the thread regarding the port of gphoto. Unfortunately gphoto never got me further than list the photos in the camera and then hang and reboot.

Well then I noticed Eostimesync

a nice utility that syncs the time of your camera to the time of the n800. Well eostimesync never "worked as advertised for me" :) BUT:

I wanted to know how it works. To make a long story short eostimesync uses a command line program named s10sh which is an userspace usb driver for canon cameras (many of them if I'm corect).

First thing linux taught me in 1998 was command --help

So as root s10sh has the ability to:
  • Get ALL/ALL NEW images
  • List ALL/ALL NEW images
  • Set camera to computer time

and many more. The above are non interactive and are the one useful for me. If you run simply s10sh it will give you an interactive shell similar to a DOS prompt. Of course your camera has to be connected by usb and your tablet in HOST mode. Oh and my camera has two usb modes "normal" - which is the canon proprietary format and the one that works with all the above and PTP which is only for image download. On your camera the modes could be labeled differently.

Oh and did I mentioned that running:

Code:
s10sh -c
does, according to the --help:

capture an image with the current camera settings

get it :D

Code:
#s10sh -c (capture)
#s10sh -n (get all new images, non-interactive)
#quiver (see what you shot on the big screen)
See why I'm so excited about?

Oh and the camera is completely functional even when connected. I can shoot, change settings anything. I do landscapes a lot so I could imagine myself leaving the camera on the tripod and the n800 connected to use as trigger or big screen for more detail. also it would be helpful when doing macro. And of course it's a LOT of FUN !

I also think you can change camera settings but I didn't explore that.

I hope you're not bored...

Let me know what you think.

So unless I dump my Nikon and buy a Canon it's back to struggling with gphoto2?

s'not fair!

Don't have an EOS, but just curious what sort of throughput you can get? any sort of live preview (video feed)? or at least remotely set the resolution to 640x480 or 800x600, repeatedly capture and view pictures (and maybe delete old ones), then set the resolution back high to capture the real thing? I have no clue if the interface supports such, but it'd be cool.

I tried s10sh with a Canon PowerShot S50. It didn't recognize the camera, and caused a lock-up then reboot of the device. I tried various different settings (except the "unsafe" -Z mode) all with the same results. It found the camera, didn't recognize it, and then froze and rebooted my N800.

I think you probably have to install the CHDK hack - I would recommend it for all the other things it will do - raw, histogram, zebra and many, many more! It supports most Canon cameras with Digic ii and iii processor chips. A wonderful hack

Is it just me, or does everyone else have bits of this thread missing - the photo seems to push the text boundary outside the visible area in my browser (Firefox).

Stop using that abominable forum theme; it displays fine in Classic (w/ some userContent.css fudges).

I guess your camera must be supported by s10sh. I tried but couldn't find a list. On it's home page it lists a few powershot models but obviously it works with more

Well if I shoot, then I must wait a few secs for the image to get to the card then I can "get all new images" and the picture transfer in another two seconds. That's all command line (until some good soul writes a python gui for s10sh ... please :) ). So I guess the minimum would be around 20 secs from shoot to download not counting load time in an image viewer. So, no, it's not good for a live preview. But it's good if you shoot landscape, or macro and want to check focus, and so on.

The CHDK firmware enhancement doesn't seem to list the S50 anywhere in the wiki. That's a bad sign.

EDIT: Confirmed: it doesn't work.
