Hi, problem... Can't find i2c core in qsys. Is there this core by default there??/ If not. I have downloaded OpenCores I2C component. But question how can I add it to qsys???? Do I have create new component and ........ . Or there is easy way ?? Thank you. Eduardas

No there is not i2c core in SOPC or Qsys. You don't have to create a new component in Qsys, go to quartus installation directory, then ip directory, create a new directory with desired name and add the core to that directory or alternatively You can add it to ip->altera directory. Otherwise copy the core directory wherever You want and add a new search path in Qsys settings.

--- Quote Start --- Otherwise copy the core directory wherever You want and add a new search path in Qsys settings. --- Quote End --- Which I2C file do You mean? The only one , that seems to be relevant is: \altera_12.1_177\ip\altera\sopc_builder_ip\altera_mp32\HAL\src\alt_iic.c I added this path to IP search path in Qsys settings and refreshed the system. But I2C QSys component did not appear in QSys Library .... Or maybe I cannot find it , where in QSys Library should it appear ? Or maybe alt_iic.c is not enough to create I2C QSys component?

.c or .h files have nothing common with qsys components...

What is the extension ( .* ) of needed I2C files which corresponds to I2C QSys component? If successfully added, then in what section of QSys Library should I2C QSys component appear?

I added the whole directory \altera_12.1_177 to IP search path in Qsys settings and refreshed the system. But no new QSys component appeared in QSys Library ...

Do you know this core will work on Quartus 12.1 SP1 SOPC ?

Create a folder named ip in your project directory which contains the .qsys file. Then add the i2c_opencores in the ip folder.

Refresh the system in Qsys to get rid of the error.

Thanks,
