... better and more complete than ever now. We were supporting via embedded Python Gxsm settings and scan control since ever, but now it getting better and more involved than ever -- plus the ease of use and management of a (growing) set of default actions and tools fully customizable.
The latest addition includes a more complete set of data access commands for read/write of pixel data and new scan creation from python numpy array data. So guess what -- you can now seamlessly play with some python math directly acessing scan data and send it right back to a scan to visualize via gxsm or even do some actions depending on it...... read more
The GXSM3 build in Python command set was enhanced including some minor comand name adjustments.
Please refer to the build in gxsm.help () function for a most up-to-date information and comand list, simply use the "Help" Menuitem in the Pyton Console and execute the provide help script -- then see the consol output!
Most importantly: gnuim/export is now simply "gxsm.import () and .export ()".
New: Live scan data access function to get andput pixel values in 4D (well, so far 3D, time not yet supported, soon, stay tunded.) And a scan write function to dump am python array into a scan, int or float type versions are available.... read more
FROM THE SVN LOG:
WARNING: a lot of rework, may be unstable.
After final patches and tests of the new wave form generation (coarse motion modes) for MK2 and MK3 we announce the current SVN version to be stable and a SVN tag and copy was generated:
svn/tags/Gxsm-3.0-20170828-stable 33 seconds ago zahl [r4851] tagging stable version V3.46.0 Action Eclipse
Please note, if you are updating from any older version (previous stable tag or older) you must update also the DSP code to match the DSP code provided within this SVN version.... read more
I added features "action-click areas" to scope widget to toggle new features:
-XY mode toggle
-fade setting for XY in time
-FT-X/FT-Y options, three states XT, FT, XT+FT for X and Y -- computes rfft of data, plots normalized magnitude
-dB scale (log) option for X and Y channels (10 dB/div -> +/-100 dB range), 0 dB := set signal scale
-mode/options status display
slightly updated design, setting info overlay (temporary if adjusted or scope is clicked)... read more
Updates on the lates tSVN version of GXSM3 V3.45.13 "Red-Force-3DS * Actionist".
Use this stable version until further notice:
The current SVN is requiring a new experimental DSP code for MK2 and MK3. The Mover module (Coarse motion wave form generation) is currently undergoing a redesign and the current version is only tested with the MK3 using a sawtooth wave, the only currently available new wave form pattern. More exciting new and more option to support complexer muilti channel wave form (up to 6 simultaneous channels possible) is under development.
I just created a tag for the "Last Gxsm-3.0 version (very stable) which is still DSP code MK2/3 compatible with the last Gxsm2 (obsoleted now)":
svn/tags/Gxsm-3.0-20170518-stable -m "Last stable Gxsm-2 DSP code MK2/3 level compatible Gxsm-3.0 version, very stable"
Please be advised:
Soon updated DSP and Gxsm/HwI code will be commited the Gxsm-3.0 main repository (trunc) and we may encounter minor glitches within new and experimental development code effecting the coarse motion control module while the Mover/Wave generation is undergoing a major overhaul. Simpler, more DSP code efficient while at the same time providing maximum flexibuility and up to 6 free simultaneous freely programmable wave forms!
Moving on to GXSM-3 Version 3.44.0 "Red-Force-3rd Dimension".
Just reworked the file load option for "replace" and "append in time" modes. Now The main File menu has a new submenu where you can select the current load mode. Default is still append in time if you open via DnD on top of an existing scan channel.
Some internal modernizations and cleanups plus removal of the old preferences option.
But more importantely I added a new load more named "stitch-2d". As the name suggests this is automatically stitching scans into one 2D view using the original scan as resolution template, expands the ranges/size as needed and so far simply my given geometry (size, absolut offsets) the new position and scaling is determined.... read more
So now it's about for the frist time after the old legacy GL 3D stoppeed working... GXSM has a basic 3D view again!
A recent upgrade to data acquisition and visualization software more than 20 years in the making enhances scientists' ability to observe and control individual atoms and molecular interactions.

Here is a little demonstration of a simple VP program with simple repeat block doing some fun.
Basically I want you to look at the vector components LM-dX and LM-dY. BTW, that's where the name LM originates from = Lateral Manipulation. However, it can do much more and this may change in future into simply "VP".
See here how the input looks for the user:

With the release of Gxsm-3 -- V3.42.0 "Red-Force-One" -- and it's final tweaks from 3.41.x we now officially obsolete Gxsm-2. There are no planns in continuing any work on this pre-gtk3 version, in particular as there are unfixable multi threadding issue we had a long fight with to get some what under control. Now in gtk this all has a clean new solution and works absolutely flawlessy on most modern machines :) Also there is nothing left to be ported any more and Gxsm-3 is to date already super seeding Gxsm2 in several aspects. Below is a summary of the lastest developments. See also new screenshots added to project!... read more
Happy New Year 2017!
Gxsm-3.0 -- V3.41.0 "Red Force One" is now released:
After several tweaks and stability and more "fool proof hardening", tracking down a hopefully final multi threadding stability issue missed so far -- related to simple GUI (filename and number) update out of a thread, fixed some missed (while porting) incompatible side pane callbacks among other details it's now working rock solid here with a low temp STM/AFM and on my testing systems as well.... read more
Gxsm-3.0 is now released and available via the main SVN trunk and set to default checkout link. It depends on a recent gnome / gtk-3.0 system. Tested with the MK3. The MK2 works as well, but is at this time less "life" tested.
Gxsm-2.0 is still availbale and will be for some time but main stream support and updates will focus on Gxsm-3.0 from now on.
Note: As of now DSP code is 100% the same what means you can at any time switch between gxsm-2.0 and 3.0 -- but I see a time not far form now this will now be the case any more.
So far still testing the Beta version of Gxsm-3.0-beta for final tweaks:
Please check it out and provide valuable feedback!
Happy to discuss anything in person.
Do not miss my talk Friday morning.
here it finally is:
GXSM Signal Master Evolved V3.10.4 is now in SVN. I'd call this a now finally a well proven solid production version.
Only critical bug fixes will go into this from now on.
A major project started on actual full porting to GTK3.4 and later.
Most trivialities are already done porting a gazillion of obsolete gnome and gtk2 functions. A lot of recursive sed action, plugins are done with all trivia ports already. Several jobs a like...... read more
A few new features, fixes and minor "speciality" pending ports in 3.10.1 -- currently in testing:
Gxsm version "Signal Master Evolved", just committed a few final touches and minor fixes.
Now full signal propagation and management via Gxsm including proper unit & scaling support derived from signal definition table. All life, actual settings read back from DSP at Gxsm startup and refresh at scan start (in case of external manipulations).
Mixer channel signal selections are now reflected by signal name in Channelselector and also automatically used as Scan title/file name.... read more
Check out a few over due updates on our http://gxsm.sf.net website and study the poster available there we presented at the ICN+T, Vail, Colorado recently!
A very successful meeting, a lot of in person interaction and discussions with Gxsm users and several interested scientists! A minimal life demo for GXSM+MK3/PLL for hands on.
And there are already NEWs evolving out of it!... read more
A big move forward to GXSM 3.01.0 "Signal Master" in particular for all MK3-Pro/A810-PLL owners. A major SVN merge from development branch/Gxsm-2x3-transition-sig into trunk was performed today.
Plus a few follow ups and merges on independent work by Niv implementing a Python console to make the pyremote more user-friendly and at the same time addressing a instability issue related to consecutive script calls.... read more
The whole GXSM CVS repository is from now on "frozen" (well, no in a hard manner) but there should be no commits any more be done -- as it is obsoleted by a now completed transition to SVN.
As of now (to be precise 2014-01-15) the CVS is fully ported to SVN -- Thanks Thorsten!
Both as of now have a stable release in the main trunc tree.
There were a few recent updated related to MK2 and MK2 -- it is highly advised to update your software.... read more
