Hi all

I am using 4 sensors on my project. These are comminicated with stm32f4 board via I2C. However there ara 3 I2C channel on stm32f4 board. Is it possible to connect them to same channel via  ı2c multiplexer ? As ı researched, the multiplexer is used with the same sensors. The multiplexer i mentionoed is TCA9548A.

Maybe this will help you: https://wiki.st.com/stm32mcu/wiki/Getting_started_with_I2C

 

This is for STM32L4, but may be of use:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
