I want to get my Raspberry Pi working with a DS1307 over I2C. The Pi is 3.3v and the 1307 is 5v. Will this circuit work for communicating between the two? I found it on this page. Is there anything else I will need to get it going? This tutorial says that it needs to be bi-directional, does this circuit give me that, or do I need to double up on everything to get both directions?
Thanks.
Thanks.
