NAME

Lab::Connection::LinuxGPIB - LinuxGPIB connection

SYNOPSIS

This is not called directly. To make a GPIB suppporting instrument use Lab::Connection::LinuxGPIB, set the connection_type parameter accordingly:

$instrument = new HP34401A( connection_type => 'LinuxGPIB', gpib_board => 0, gpib_address => 14 )

DESCRIPTION

Lab::Connection::LinuxGPIB provides a GPIB-type connection with the bus Lab::Bus::LinuxGPIB, using Linux GPIB (aka libgpib0 in debian) as backend.

It inherits from Lab::Connection::GPIB and subsequently from Lab::Connection.

For Lab::Bus::LinuxGPIB, the generic methods of Lab::Connection suffice, so only a few defaults are set: wait_status=>0, # usec; wait_query=>10, # usec; read_length=>1000, # bytes

CONSTRUCTOR

new

 my $connection = new Lab::Connection::LinuxGPIB(
    gpib_board => 0,
    gpib_address => $address,
    gpib_saddress => $secondary_address
 }

METHODS

This just falls back on the methods inherited from Lab::Connection.

config

Provides unified access to the fields in initial @_ to all the child classes. E.g.

 $GPIB_Address=$instrument->Config(gpib_address);

Without arguments, returns a reference to the complete $self->Config aka @_ of the constructor.

 $Config = $connection->Config();
 $GPIB_Address = $connection->Config()->{'gpib_address'};
 

CAVEATS/BUGS

Probably few. Mostly because there's not a lot to be done here. Please report.
