Hi , i'm currently developing a circuit with the STM32F051C6Tx.

When i select the Cpu in CubeMx i can not selct the I2C2 on PB10/PB11, there is just the I2C1 on PB7/PB6. As i read in the Datasheet befor there have to be a I2C2 on PB10/11 (Datasheet Page33/115). So the question, is the Datasheet wrong or is the I2C2 simple missing in CubeMx ?

Regards, Sebastian

Hi Sebastian J.,

Go to the page 10/115 (table2), the third footnote indicates that I2C2 is not present. So, ther is no bug related to CubeMx.

Your right. Thank you . It was my fault. So i have to use I2C1.
