Introduction
- http://www.ni.com/gpib/what_is.htm / http://en.wikipedia.org/wiki/IEEE-488
- it is one of a communication standard of most equipments
- A interface(in both hw & sw) to any platforms, such as dspic33 board, bf1 board ...
interface
IEEE 488 specifies a 24-pin connector and shielded cable:
- 8 lines used for bi-directional data, sent a byte (8 bits) at a time
- 8 lines used for handshake and bus management
- 8 ground return lines, including pin 12 connected to the cable shield and the connector shell
(See also Expansion bus)
IEC bus
The 6-pin DIN "serial" interface of the Commodore 64 ("Commodore serial bus", also called the "IEC bus") is intended to be a low-cost alternative to IEEE-488, using more-or-less the same high-level protocol and a similar daisy-chain from the controller to many peripherals, but using a much lower-cost 6-pin connector and cable, transmitting the 8 data bits and most of the control information serially over a single bi-directional data line. (see "Commodore Peripheral Bus: Part 4: Standard Serial" by Michael Steil).
I2C protocol
- apply as one to many(can be different kind of devices)
- different platforms
- for dspic, sw driver implement in freertos following posix arch.
- for bf1 pf, sw driver implment in uclinux following posix arch.
