Problem with DS1307 on KC868-A6

[Ramalcu]

can you use this DS1307 arduino code to test it?

I tried the code and it doesn't work. There are no signals on SCL nor SDA seen on my logic analyser. I guess the I2C pins are not mapped on that code, right?

Where can the I2C pins be configured properly to work with DS1307 lib on that code?

Thank you.
