Yeah sure. First of all which version of the core are you using? There's an old (simple_i2c) and the i2c_master core. Use the latter; map it into the DSP's memory range and access it as though it's a memory device. Read the documentation for the register addresses.

I need to implement an i2c bus for a project. I am using a dsp to send commands to registers in an fpga from where I will control the i2c. I am using an existing reference design for my development board. Can anyone please help me with something? I got the documentation for the i2c master core written by R. Herveille. I know that I need to write to registers to read and write, but I don't know how to access those registers using the reference design. In other words, I just need to know if anyone can help me to integrate the i2c controller using the reference design? Thank you.
