i2c and display help

[Altera_Forum]

Hello, 

 I have a Nios2 dev board (cyclone ii edition) from ALtera. I managed to load uClinux, and run it nicely. I have been able to run the LEDs and the push buttons, and ethernet.  However, I have been struggling to get I2C, SPI and 2-line char display going.  Can anyone give an insight, where I can get those IPCORE (i2c, spi) and drivers and sample app for running those things ?  I saw there is something on opencores.org, but i have no idea how to integrate them using Altrea's tools, and no way i can write drivers for them.  Perhaps this is something hippo can help.  Thanks.  Albert
