I was unable to retrive data from RTC DS3231 using I2C.

And I am perfectly getting from ADXl325 accelerometer using I2C.

RTC DS3231 works perfectly with arduino mega 2560 but problem getting data for STM32F103C8T6.

Dont know why?

I am using STM32CubeMX and TrueSTUDIO

Hi

HAL I2C relative functions, require the Slave Address of DS3231 to be shifted one bit left to work.
