NAME

Device::GPIB - Perl extension to access a variety of generic and specific GPIB devices, via a number of supported GPIB interfaces.

Generic command line programs can be used to scan the GPIB bus and to send arbitrary commands and queries to any device that supports GPIB.

Perl Modules and command line programs to access specific features of a number of HP, Tektronix and Advantest devices are also provided.

Supports a number of GPIB interfaces and controllers including: Prologix GPIB-USB Controller and compatibles, including: AR488 for Arduino from Twilight-Logic: https://github.com/Twilight-Logic/AR488 (tested with Arduino Nano and custom wiring interface) LinuxGpib compatible devices (requires linux-gpib from https://sourceforge.net/projects/linux-gpib) (Tested with Keysight 82357B)

This module obsoletes and replaces the earlier Device::GPIB::Prologix module from the same author.

SYNOPSIS

# Low level access to Controller use Device::GPIB::Controller; my $port = 'Prologix:/dev/ttyUSB0:115200'; my $d = Device::GPIB::Controller->new($port); # Can now use $d->....

# Open a specific GPIB device with address use Device::GPIB::HP::HP3577A; my $address = 11; my $na = Device::GPIB::HP::HP3577A->new($d, $address); $na->plot();

DESCRIPTION

Device::GPIB::Controller->new($port); A wrapper that will load the appropriate Controller module depending on a port/device specification argument passed to it. The following port/device names are supported:

Prologix:[Prologix:[port[:baud:databits:parity:stopbits:handshake]]] LinuxGpib:[board_index]] port[:baud:databits:parity:stopbits:handshake]]

Examples:

'' # Defaults to Prologix:/dev/ttyUSB0:9600:8:none:1:none '/dev/ttyACM0' # Prologix:/dev/ttyACM:9600:8:none:1:none 'Prologix:/dev/ttyUSB1:115200' # Prologix:/dev/ttyUSB1:15200:8:none:1:none 'LinuxGpib:0' # Linux GPIB board index 0 (see /etc/gpib.conf)

You can of course load specific Controllers directly: use Device::GPIB::Controllers::Prologix; my $d = Device::GPIB::Controllers::Prologix>new('/dev/ttyUSB0:115200'); ...

or

use Device::GPIB::Controllers::LinuxGpib; my $d = Device::GPIB::Controllers::LinuxGpib(1); ...

After a Controller is opened, you can load a perl module with suport for the specific functions ao any of the suported GPIB devices with something like:

use Device::GPIB::HP::HP3577A; ... my $na = Device::GPIB::HP::HP3577A->new($d, $address); exit unless $na;

and then do things like: my $screendump = $na->sendAndRead('PLA'); # Get HPGL

or

my $instrumentstate = $na->lmo(); # Get current instrument state for saving

Of course the list of things you can do depends on the device.

EXPORT

None by default.
