GXSM - a smart & customizeable SPM control — Percy Zahl1, •Thorsten Wagner2, and et al.3 — 1Brookhaven National Laboratory Upton, USA — 2Johannes Kepler University Linz, Austria — 3http://gxsm.sf.net
The open source and community driven scanning probe microscopy software project GXSM takes the next level to provide a highly and in-operando adaptable scanning probe microscopy (SPM) control system. A highly efficient digital signal processor (DSP) interfaces any SPM to a Linux based PC. Via a gnome based graphical user interface (GUI) standard tasks like scanning can be easily performed. The GUI allows the user also to control highly advanced tasks like mapping and probing/manipulations. Standalone, i.e., without DSP hardware, GXSM can perform image analysis and multidimensional visualization.
GXSM is based on an object oriented (C++) and modular design. Since 15 years this structure was flexible enough to adapt any further development. Plug-ins are available for background correction, data analysis, math feature detection (via the OpenCV library), statistics, scan data im-/export, and Python scripting remote control. In particular, the hardware interface is also based on this plug-in structure allowing to adapt for various DSP hardware.
In this contribution we will report on the recent developments to adapt more flexible to different SPM configurations via a kind of hot-plug signal routing on the DSP level. We will also give a status report on the efforts to migrate GXSM to the latest GTK/Gnome environment.
