visa

Go-based Virtual Instrument Software Architecture (VISA) resource manager, which can be used by itself to send Standard Commands for Programmable Instruments (SCPI) commands, or to provide an interface for Interchangeable Virtual Instrument (IVI) drivers.

Background

The primary purpose of this package is to parse a VISA resource address string in order to create a new VISA resource, which abstracts the interface type—USBTMC, TCPIP, ASRL. By registering a driver for the interface type, application developers can decide which interface types to support and which to exclude, so as to not unnecessarily bloat their packages.

The primary source of information is the VPP-4.3: The VISA Library dated June 19, 2014, which can be found at the IVI Specifications webpage.

Usage

In order to not bloat an end developer's application, the desired HW interface driver(s) have to be registered, similar to Go's SQL package. Currently, there are TCPIP (LXI), USBTMC, and Serial (ASRL) drivers available.
