Trouble initializing the I2C interface

[emmanuelkatto]

Hi everyone, My name is Emmanuel Katto. I am having trouble initializing the I2C interface on the STM32F4 series. Could someone provide a simple example or point me to resources that detail the setup process?

Looking forward to your responses.

Thanks in advance!

Best,

Emmanuel Katto

Welcome to the forum.

You posted this under STM8 - I've moved it to STM32 for you.

The best way to get started would be with an STM32F4 Nucleo board

If you're using STM32CubeIDE, start a project for one of the Nucleo boards;  there are examples which illustrate most of the STM32's features - including I2C.
