STM32F107 I2C1 & I2C2

Hello,

I am going to replace STM32F107 instead of F105 in my design, and as I see F107 has only one serial interface I2C1. In my case, I need both I2C1 and I2C2.

Is there any way I can remap or define some pins as I2C2?

Thank you.

Hello @NASI​ ,

STM32F107 has only I2C1 available.

I2C2 is not available on STM32F107, and there is no alternate config to use.
