node-nisa32

This project was superseded by node-nisa The problem was that in order to implement SRQ events, the list of all connection objects needed to be maintained.. therefore the FFI idea didn't work anymore. It may stil be smart in some circumstances.....

nisa32 is another prototype for using VISA library in node.js. This is a wrapper for visa32.dll (in your system32 folder).

I tested this code on Windows 8.1 (64bit), Keysight IO Library (17.1), node.js

Talked to HP 6623A...

You must have Keysight or National Instruments VISA drivers installed. You need to have compatible interface and and instrument that talks over GPIB. For simple testing you can skip the hardware part as VISA can talk over COM ports, too.

> npm install node-nisa32

var visa = require('node-nisa32');

visa.query("GPIB0::12::INSTR", "*IDN?", function(err, result) {
 // do something
}
