Description

The library, and the administration tool gpib_config(8), read their configuration information from the file /etc/gpib.conf. A template gpib.conf file can be found in the util/templates/ subdirectory of the linux-gpib package.

The configuration file must contain one or more “interface” entries, and can contain zero or more “device” entries. “device” entries are only required if you wish to open device descriptors with ibfind() instead of using ibdev(). Several example entries, and a table summarizing the possible options follow.

interface {
    minor = 0
    board_type = "ni_pci"
    pad = 0
    master = yes
}

interface {
    minor = 1
    board_type = "ines_pci"
    name = "joe"
    pad = 5
    sad = 0
    timeout = T10s
    pci_bus = 0
    pci_slot = 0xd
    master = no
}

interface {
    minor = 2
    board_type = "pcII"
    pad = 3
    sad = 0x62
    eos = 0x0d
    set-reos = yes
    set-bin = no
    set-xeos = no
    set-eot = yes
    base = 0x300
    irq  = 5
    dma  = 0
    master = no
}

device {
    minor = 0
    name = "counter"
    pad = 24
}

device {
    minor = 0
    name = "voltmeter"
    pad = 7
    sad = 110
    eos = 0xa
    set-reos = yes
    set-bin = no
    set-xeos = yes
    set-eot = no
    timeout = T1s
}
