how to activate I2C
Good morning
I'm trying to make a project that requires the I2C1 bus work
if I load the compiled project on arduino
from debug the application crashes because it can't read the EEPROM on RTC
I've read various documents but I can't understand how to activate the bus on the STMF411 processor
I'm quite new to STM
with esp32 there are no problems
here it seems more complicated to me

STM32F4 series

Yes, programming hardware frequently more complicated than presented by Arduino where someone else has worked out the drivers and libraries

The 7-bit Slave Address on STM32 is the High Order 7-bits, not the Low Order. So frequently (SlaveAddr << 1) in translation/conversion.

Look at the documentation for the IC you are connecting, usually sets forth the expectations.

Hello @ezioall ,

You can refer to this example from STMicroelectronics: I2C_TwoBoards_ComPolling Example. This example demonstrates how to handle I2C communication between two boards, which might be helpful for your case involving STM32 and Arduino.
