a newbie in FPGA asks for help

[mateushh]

Hello!

I am a newbie in this topic, so excuse me, if the topic seems stupid. :wink:

Anyway, if you would help me I'd be grateful!

I would like to implement an i2c interface on an FPGA chip using the Xilinx environment. All I need is a scheme (I mean gates and flip-flops) or a description of such interface in VHDL or Verilog languages. I tried to look for it at Philips website, but all I found was only the shemes that described the idea of the interface.

Do you have any suggestions or ideas? Or mayby you could give me a hint, if it is actually possible or where to start to look for it?

Thanks in advance

Mateush

check https://www.opencores.org

Click browse projects, you will see a free VHDL I2C controller core for you to directly implement in your xilinx part.

I think Xilinx has an app note with VDHL and Verilog code for an I2C controller. If you do a search on their web site you should be able to find it; they do make it a bit difficult to find their app notes though.
