Lua scan This simple client scans topography in contact mode, using Lua script, going point by point. It connects to the server and sets the operation regime to proportional feedback (typically used in contact mode, difference between value of signal on input and some setpoint value makes piezo to extend or shrink, depending on settings). Then it sets some basic parameters of feedback loop and sets feedback on. It sets the scanning velocity and then it scans

Gwyscope GUI overview Gwyscope is primarily designed to allow development of user's own interface, i.e. a client which connects to the server running on the hardware. A sample graphical user interface described in this section is only one of all the possible realizations of such client and therefore is far from being complete and optimized.

Connection test This simple clients tests the client-server connection. It connects to the Gwyscope server and gets raw information about server start time. After that it reads 20 values of what is the actual “error signal” and exits. It can be used to learn how to set up the connection over Ethernet and how the Gwyfile object based messages used for communication are set up and passed through the connection.

Scan by lines This simple client scans topography in contact mode, measuring a collection of individual profiles. It connects to the server and sets the operation regime to proportional feedback (typically used in contact mode, difference between value of signal on input and some setpoint value makes piezo to extend or shrink, depending on settings). Then it sets some basic parameters of feedback loop and sets feedback on. It sets the scanning velocity and then it scans

Ramp This simple client performs a ramp in z-piezo direction. It connects to the server and sets the operation regime to proportional feedback (typically used in contact mode, difference between value of signal on input and some setpoint value makes piezo to extend or shrink, depending on settings). Then it sets some basic parameters of feedback loop and sets feedback on. After that it runs a ramp (a force-distance curve) and prints it (in C) or shows it (in Python), Finally, it stops the feed…

Lua Line scan This simple client scans topography in contact mode, using Lua script, measuring a collection of individual profiles. It connects to the server and sets the operation regime to proportional feedback (typically used in contact mode, difference between value of signal on input and some setpoint value makes piezo to extend or shrink, depending on settings). Then it sets some basic parameters of feedback loop and sets feedback on. It sets the scanning velocity and then it scans
