Get started with a pair of STM32 evaluation boards such as the NUCLEO or Discovery boards. Download the STM32Cube software package associated with your evaluation boards. Build and run the I2C example project included in the STM32Cube package. Set the I2C peripheral (clocks, timings etc etc). Set one device as MASTER and the other as SLAVE. Set the SLAVE device address (I2C peripheral I2C_OAR1 register). Master sends the START with SLAVE device address and SLAVE dice ACKs it. You can communicate between the devices.
