This is a guide to wrap NI visa32.dll (lib) in octave on Windows10 PC for instrument control .
I have try it and compile a .oct file , then it works on windows octave. four base functions are working well !
################################################################################################# below is something need to install:
-
install NI visa32 , my version is download from "RIGOL TECHNOLOGIES" https://www.rigolna.com/products/digital-oscilloscopes/1000z/ find "UltraSigma Instrument Connectivity Driver"
-
octave Version: https://ftpmirror.gnu.org/octave/windows/octave-6.4.0-w64-installer.exe octave-6.4.0-w64-installer.exe
-
copy *.h & lib file to local octave path:
visa.h , visatype.h , and visa32.lib file ( Note： that there is a 64 bit and 32bits version of visa32..... )
"C:\Program Files\IVI Foundation\VISA\Win64\Lib_x64\msc\visa32.lib"
this one is ok.
and the *.h file:
C:\Program Files\IVI Foundation\VISA\Win64\Include\visa.h
C:\Program Files (x86)\IVI Foundation\VISA\WinNT\include\visatype.h
-
in octave gui ,run cmd: mkoctfile visa_tb_windows_wrap.cc -L. -lvisa32
-
then you will see a "visa_tb_windows_wrap.oct" file . try to modify test_script.m do you own test!!!
instid = viopen("TCPIP::192.168.3.84::INSTR");
viwrite(instid, "*idn?");
viread(instid);
viwrite(instid, ":MEAS:freq?");
viread(instid);
log like this:
