I2C Controller's verilog,VHDL Source code,Testdench



I2C project properties

Category :: Communication controller
Language :: Verilog
Standard :: Wishbone compliant core
Development status :: Production/Stable

Description

I2C is a two-wire, bidirectional serial bus that provides a simple, efficient method of data exchange between devices. It is primarily used in the consumer and telecom market sector and as a board level communications protocol. The OpenCores I2C Master Core provides an interface between a Wishbone Master and an I2C bus.
It is an easy path to add I2C capabilities to any Wishbone compatible system.

You can find the I2C specifications on Phillips web Site. Work was originally started by Frédéric Renet. You can find his webpage here .
