I2C Controller

Hi, I have an FPGA design that relies on a couple "constants" in registers that I would like to make changeable over an I2C interface. Does anyone know if there is a standalone core I could us...

I'm using a USB controller (FX2LP) that is communicating with the FPGA, but from what I've read the FX2LP doesn't have a SPI interface. It has standard serial pins, but that's not the same, is it? I've never used SPI so I don't know what's involved. When you say easier do you mean more cores are available or is it just a simpler protocol?

Meanwhile I'll take a look at the design FvM sent. Thanks for that.
