IEEE-488 is a short-range, digital communications bus specification that has been in use for over 30 years. Originally created for use with automated test equipment, the standard is still in wide use for that purpose. IEEE-488 is also commonly known as HP-IB (Hewlett-Packard Instrument Bus) and GPIB (General Purpose Interface Bus).

IEEE-488 allows up to 15 devices to share a single 8-bit parallel electrical bus by daisy chaining connections. The slowest device participates in control and data transfer handshakes to determine the speed of the transaction. The maximum data rate is about one Mbyte/s in the original standard, and about 8 Mbyte/s with later extensions.

The IEEE-488 bus employs 16 signal lines — eight bi-directional used for data transfer, three for handshake, and five for bus management — plus eight ground return lines.

      HTBasic GPIB Tutorial

      The IEEE-488 bus was developed to connect and control programmable instruments, and to provide a standard interface for communication between instruments from different sources. Hewlett-Packard originally developed the interfacing technique, and called it HP-IB. The interface quickly gained popularity in the computer industry. Because the interface was so versatile, the IEEE committee renamed it GPIB (General Purpose interface Bus).

      GPIB Tutorial

      Instrumentation has always leveraged off widely used electronics technology to drive its innovation. The jeweled movement of the clock was first used to build analog meters. The variable capacitor, the variable resistor, and the vacuum tube from radios were used to pioneer the first electronic instruments. Display technology was leveraged off the television for use in oscilloscopes and analyzers.

      Linux GPIB Package

      The Linux GPIB Package is a support package for GPIB (IEEE 488) hardware. The package contains kernel driver modules, and a C user-space library with Guile, Perl, PHP, Python and TCL bindings. The API of the C library is intended to be compatible with National Instrument's GPIB library. The Linux GPIB Package is licensed under the GNU General Public License.

Mark Twain quote for the day:

Will a day come when the race will detect the funniness of these juvenilities and laugh at them- and by laughing at them destroy them? For your race, in its poverty, has unquestionably one really effective weapon- laughter. Power, Money, Persuasion, Supplication, Persecution- these can lift at a colossal humbug,- push it a little- crowd it a little- weaken it a little, century by century: but only Laughter can blow it to rags and atoms at a blast. Against the assault of Laughter nothing can stand.
