The SDA is in "1" and the SCL "0", getting static. Put two pull-ups in (SDA and SCL) 4k7, but nothing work.Case, someone can help me, my code follows in the AnnexThank you! main_A.txt main_B.txt Quote Link to post Share on other sites
bluehash 1,581 Posted April 1, 2014 Share Posted April 1, 2014 Hi @@leonardo , Welcome! What are you interfacing to? You should at least see a clock if nothing is connected to the Stellaris. Also, try to use an example and build up from there. Quote Link to post Share on other sites
Mr.Cruz 0 Posted April 4, 2014 Share Posted April 4, 2014 Dunno if the title was meant to be a question or an expression, but I can assure you that I2C does work. If you'd like to simply test your setup, I have a project that scans I2C0 here. If you're looking for something that's more library-like, take a look at this. I could provide more details as to why the library decided to do this, but I have other things I'm working on atm. Quote Link to post Share on other sites
