Master Slave using I2C

Post by peeknot » Tue Jan 30, 2018 1:20 pm

I have a "bluepill" serves as master and a "arduino due" as a slave. Im trying to test this example ... anner_wire if the bluepill can detect the due
No I2C devices found
, I connect the sda and scl of the due to bluepill`s pin PB7,PB6 simultaneously. But it cant scan anything , note this is my first try on using master slave communication. or a newbie wanna be. Im browsing some old post regarding to this but the ones I see was old ones , any ideas will be a big help.
