3. Software
The TT-2 AFM includes three separate software modules in the AFM Installation files:
AFM Workshop Acquisition Software, Video Microscope Software, and Gwyddion Image
Analysis Software. This installation guide is targeted towards a computer running Windows
OS.
3.1 Installation Procedure
NOTE: If the target computer has a previous version of LabVIEW installed, it
is imperative that it first be completely removed.
Locate the provided AFM installation files for the USB camera, Gwyddion, and AFM software
and follow the prompts.The user will be asked to input his/her scanner size, so that the setup
procedure will copy the files that correlate with that scanner size onto the desktop. Reboot
when directed. All instructions can be found in the readme file.
NOTE: A Windows Security pop-up will appear when installing the Video
Microscope driver that states that Windows cannot verify the publisher of the
driver software. Choose the option to "Install this driver software anyway."
Upon initializing the AFM-View software, the user will be asked to confirm the serial number
of the National Instruments DAQ card in the Ebox. The software will display this pop-up
every time the user plugs in a different Ebox.

Gwyddion is open-source software and the latest version of this image-analysis software
is available on the Internet at: http://gwyddion.net/. The functions of the Gwyddion image
analysis software are:
