Python Interface Package for Nanonis

Official python package for the Nanonis SPM Controller software.

Usage

This package allows users of the Nanonis SPM Controller software to use and control said software through python commands.

How to use

Importing

import nanonis_spm

Initializing Connection through the socket module

import socket

connection = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

connection.connect((IP_ADRESS_HERE, PORT_HERE))

nanonisInstance = nanonis_spm.Nanonis(connection)

NOTE : THE PORT HAS TO BE AN INTEGER AND THE IP ADRESS A STRING

Enabling Debug Console Output

The function "returnDebugInfo()" takes an integer as an argument. This integer should be either 1 = on, or 0 = off. This option is off by default.

Enable by running: nanonisInstance.returnDebugInfo(1)

Examples

There is a collection of examples installed with the package.

The description of all the available functions can be found in the TCP Protocol Document, and hovering on the function depending on the used IDE.

IMPORTANT: The TCP Interface requires every argument to be of certain size (see documentation). This is why the Numpy dependency is required, since it enables the specification of variable sizes.

Example:

nanonisInstance.BiasSwp_LimitsSet(np.float32(1), np.float32(2))

We hereby ensure that the arguments are of the correct size.

Change Log

1.0.9

Added missing argument to TCPLog_ChsSet. Fixed data types from f to d in Osci1T_TrigSet function.

1.0.8

Added missing argument to Motor_StartClosedLoop function.

1.0.7

Fixed the programmatic control of the Oscilloscope High Resolution graph, where some functions now include an input for channel selection to support the 4-channel version of this graph.

1.0.6

Added functions to control the hysteresis compensation in the Piezo Configuration module. Added a function to return the limits of a Bias Sweep. Added a new setting in the functions Scan_PropsGet and Scan_PropsSet to get-set the auto-paste feature in the Scan Control module.

1.0.5

Fixed some missing variable names in the function declaration of some MCVA and MProbe functions. Fixed missing input arguments for Motor_FreqAmpGet and Motor_PosGet functions. Added all functions for the Function Generators 1Ch and 2Chs. Fixed the SpectrumAnlzr_DataGet function.

1.0.4

Fixed the indentation of two Script functions (Script.Open and Script.LUTOpen) which triggered an error when trying to use the class. Changed the behavior of the returnDebugInfo function so that nothing is printed out if there is no error.

1.0.3

Added the function Util.VersionGet to get the software version, the MCVA5 preamplifier functions, the V5e Generic PI Controller functions, and all the MultiProbe functions (Bias, Current, Z-Controller, and scanner control) needed in a MultiProbe system.

Removed a check in the ParseError function which set a different error string offset for functions returning exactly 8 bytes. Changed the data types of the returning arguments for the BiasSpectr_ChsGet and ZSpectr_ChsGet functions.
