Subject: [oc] I2C ip core integration for ALTERA FPGAs
Did you connect clock and data signals correctly? It is a bit tricky
because you don't use the clock and data out lines for the actual data
transfer. They are always 0.
You have to use the data and output enable to make 1 and 0.
Hope it is of help.
Regands,
David
