Hi David,

http://wiki.elphel.com/index.php?title=Elphel_353_series_quick_start_guide#Getting_the_first_images:
http://192.168.0.9:8081/bimg
I'm getting the images with a (growing) Python script, the relevant part
is copied below
# get options.Images number of images
for i in range(1,options.Images+1):
print 'writing image ' + str(i) + '/' + str(options.Images)
if options.FileName:
FileName = options.FileName + '_' + str('%.04d' % i) + '.jpg'
else:
FileName = str(time.time()) + '.jpg'
# get the url of the camera which spits out an image
# save the image to 'SaveDir', with the desired name, set above
urllib.urlretrieve(
http://192.168.0.9:8081/wait/bimg;,
os.path.join(SaveDir,FileName)
)
so that part works fine :)
But - as Alexandre suggested - I'll trigger the camera externally and do
some more testing.
Thanks for the help and pointers!
David

Re: [Elphel-support] Elphel camera with Raspberry Pi
Dear all. Thanks to one of the Masterstudents here, which has extensive experience with LAN-Parties I managed to find and correct the problem. The non-working connection was not based on the auto-negotiation, but a problem of correct setting of the involved the IPs. Somehow DHCP on Raspbian [1] doesn't get it when the camera is connected. Typing $ sudo ifconfig 192.168.0.1 , unplugging and reconnecting the camera did the trick. Now I'm onto the next problem. The user-interface over 192.168.0.9/camvc.html is unuseably slow on that whimsy computer, so I need to whip up some Python code to download single images as fast as possible...

Re: [Elphel-support] Elphel camera with Raspberry Pi
David, On the camera you can use http://wiki.elphel.com/index.php?title=Parsedit.php to set camera parameters once. The camera run PHP scripts, you can see some examples here: http://wiki.elphel.com/index.php?title=PHP_Examples But all you need for your usage is to set the camera in triggered mode (external trigger) http://wiki.elphel.com/index.php?title=Trigger and use http://wiki.elphel.com/index.php?title=Imgsrv to download a single image. on Raspberry pi side all you need is wget http://192.168.0.9:8081/bimg; Regards, Alexandre Poltorak Alsenet SA - Mail original - | De: David Haberthür david.haberth...@psi.ch | À: lengacher_p patrik.lengac...@psi.ch | Cc: support-list@support.elphel.com | Envoyé: Lundi 7 Janvier 2013 16:18:03 | Objet: Re: [Elphel-support] Elphel camera with Raspberry Pi | | Dear all. | | Thanks to one of the Masterstudents here, which has extensive | experience | with LAN-Parties I managed to find and correct the problem. | The non-working connection was not based on the auto-negotiation, but | a | problem of correct setting of the involved the IPs.
