Hi, I am using STM32F100RBT6B discovery board and I need to use I2C1 bus. I saw on datasheet that gpio PB6 and PB7 should be used for clock and data. I think to use PB8 and PB9 for the alimentation. Is it correct?
Now I see that I have to use also PB4 and PB5, but which is their function for I2C1?
Thanks
