The only thing that comes to mind is that you may have some inconsistencies in sources.list file. Just to be sure I have recreated indexes on repository.
Please remove any entries regarding picoscope from /etc/apt/sources.list (or any other file you put that information to) and use command from website instructions: http://www.picotech.com/linux.html
Hi, I am using the PicoScope 3404B and I am struggling to find some features on the Pico 6 software :-
Measure windows for rulers, cant get these to appear. I can get the time ruler (shows frequency) window to appear, but that is all.
Analog input offset adjust, cant find the setting for that.
Persistence mode settings dialog, the button or menu item for that does not appear.
Measurements button or menu item.
Are these features still being worked on?
I've just installed PicoScope on my Linux Mint 16 laptop for the first time (this is also my first time using any PicoScope product).
Unfortunately the install scripts appear to have added my user account to the "pico" group but removed me from all the other groups I'd normally be part of. This has caused particular problems as I lost sudo rights which made it harder to fix.
I've had a dig through the Debian scripts and it looks like the postinst script calls "usermod -G" at some point to add the user to the "pico" group. I think that should be "usermod -G -a" so that it appends rather than replaces.
From the man page for usermod:
-G, --groups GROUP1[,GROUP2,...[,GROUPN]]]
A list of supplementary groups which the user is also a member of. Each group is separated from the next by a comma, with no intervening whitespace. The groups are subject to the same restrictions as the group given with the -g option.
If the user is currently a member of a group which is not listed, the user will be removed from the group. This behaviour can be changed via the -a option, which appends the user to the current supplementary group list.
Thanks for supporting Linux, this was one of the major reasons I chose this scope
Well spotted, close, but issue is different. When release was made for SuSe and other rpm based flavors a regression has been introduced to postinstall script. Certain versions of 'usermod' don't have '-a' option, but all support '-G GROUP1,GROUP2' syntax. To be safe I've ported those changes to Debian scripts... with critical error
So thats why my sudo membership disappeared to !! (Ubuntu 12.04) It seemed so random, I did not connect it with the picoscope install. Well its a relief to know it was not due to a meltdown of somekind anyway.
The new release is now out. Besides fixes to permissions setup in postinit scripts, it brings handful of new features:
MSO channels support
Analog offset and bandwidth filters in channel properties
Rulers*
New properties window for persistence mode
* Rulers come with certain bug - after setting initial ruler the focus is lost and second one doesn't come up. To workaround this first bring rulers pop-up into focus by clinking on it, then click back on the graph - second ruler will be possible to use now.
The main package requires additional dependency (libmono-system-runtime-serialization4.0-cil), simple 'apt-get upgrade' will keep it back. To install new version run the following:
The new version works fine on Ubuntu 12.04 (32 bit). However after a few seconds, the process "mono" maxes out the CPU cycles and the CPU fan starts to crank up noisily.
Just wanted to drop in and say thank you! Software works great on ubuntu 13.10. Only wish that i could change the background and signal colours. Using a 2204a picoscope.
We have just put another version of PicoScope for Linux. This one is to address cpu usage issue mainly. Also new feature has been added - trigger controls for MSO channels.
