I2C pins

[Rushit]

Hello,

I used STM32L031K6 Nucleo board.

When I Enable I2C it select by default PA10(SDA) & PA9(SCL) pins for Communication it not work, Then I change Pins for I2C PB7(SDA) & PB6(SCL) it work well.

so any additional configurations need for use PA10 & PA9 pins ?

Hi @Rushit 

No additionnal Configuration required.  Can you confirm me that your GPIOs are in pull up mode?
