i2c in sopc builder

[Altera_Forum]

Hello all; 

 I downloaded I2opencores, How do I use? How can I add it in SOPC builder?  thank you very much.

[Altera_Forum]

Either copy it to altera\11.1\ip\opencores\ (I've created opencores dir by myself) or copy anywhere and add a new search path in sopc builder.

Hello, I created a folder inside altera/10.1/ip but is seen by SOPC. Why? 

 thanks

[Altera_Forum]

Because. 

 You're welcome.  P.S. Please ask properly and fix Your english.

[Altera_Forum]

heh heh, 

you're right, but my English is from google translator! I do not know what the reputation button! I'm new, if you explain it to me, surely I'll use it.  In the meantime, why not work opencores? I copied the entire folder in the path: C/altera/10.1/ip/opencores  Thank you, Best Regards.

What's the full path to opencores_i2c_hw.tcl? 

Mine is: c:\altera\11.0\ip\opencores\opencores_i2c\opencores_i2c_hw.tcl

Hi, 

I did as you said and it worked. but now I have these errors:  Error: opencores_i2c_0: opencores_i2c_0.avalon_slave_0 must be connected to an Avalon-MM master  Warning: opencores_i2c: set_interface_property: export_0 Interface (conduit) can not have associatedClock  Warning: opencores_i2c_0: Interrupt opencores_i2c_0.interrupt_sender sender is not connected to an interrupt receiver  how can I fix this? thanks a lot.

Now You need to connect the core to the interconnect. I suggest You reading the SOPC Builder manual and do some example projects.

Hi, 

I have solved almost all problems. remains just that:  Warning: opencores_i2c: set_interface_property: export_0 Interface (conduit) can not have associatedClock  can you tell me what that means? and how do I take?  Once instantiated, the block can be slaves? Or is it just the master?  thanks, thanks and thanks again

--- Quote Start ---  Warning: opencores_i2c: set_interface_property: export_0 Interface (conduit) can not have associatedClock  --- Quote End ---  It is a warning coming from a recent SOPC builder on a component that was created with an older version. You can either delete the line defining the associated clock in the tcl file or just ignore the warning.

first of all thank you, 

how do I get a component i2c slave? I downloaded opencores_12c_slave, but there is no tcl.

Two solutions: 

1) Do Your own component. 2) Use bitbang method using PIO.

I have tried to make a component, but it creates a lot of mistakes. 

 What is BitBang?  Where can I study?
