Thanks for your help. I saw this page but to my best understanding, it works with wishbone, and I think i need for the NIOS Avalon.
Am I right? if i use a code from opencore do i need to publish my code? - Altera_Forum
Hi,
does this reference design not fit your needs? http://www.altera.com/support/refdesigns/sys-sol/indust_mil/ref-i2c.html Greets - Altera_Forum
Thanks. Do i get there the design verilog/vhdl code?
I did not quite understand what does this I2C Controller Reference Design mean. Is it a board? Is it a SW tool? Can I play around with the code? Many thanks in advance. - Altera_Forum
