Hello, I use STM32F469I-DISCO-REV-AU1 and want to connect RTC DS3231 as my external clock. I am trying to connect. I tried to connect using I2C but couldn't get any response on the screen after this. Can anyone help me with this?

STM32469? Do you have this board?

[JPann.1]

its STM32F469I-DISCO-REV-AU1

So the RTC is attached to the I2C connector on the board, correct?

Have you tried to debug? Do you know how to use the debugger?

Should be able to use I2C on D14(SDA)/D15(SCL) and GND from shield connector.

ST uses LEFT aligned 7-bit I2C addresses, so (addr << 1) compared to Arduino sketches
