i2c with DE2-115

Hello All,

I found this link http://www.alterawiki.com/wiki/i2c_(opencores) where there is an i2c core available (I have Quartus 12.1). But I failed to see any documentation on how to build a qsys component from this so that I can use it in Nios 2. Can some one please point me to the steps I need to take to achieve this?

Thanks so much for your time!

Best regards,

    Custom component that you can use in Qsys is already created for I2C Controller.You just need to give the path for i2c_opencores_hw.tcl in Qsys.Follow the steps given below.

    Sorry I forgot to add the stpes.

    Steps are given below.

    (1) Put I2c_opencores_12.0 in your Quartus installation directory->ip directory.

    (2) Open Qsys

    (3) You will see I2C Master(opencores.org) component.You can find it in Interface Protocols->Serial->I2C Master.
