I want to use STM32F103RB6 MCU to connect to STM8S103 MCU via I2C. Can I get data of STM8S103 via STM32F103RB6 and control the operation of STM8S103 by STM32F103RB6 via I2C interface? These two MCUs operate in different frequency. The STM8S103 MCU is the master running the electronic device. The STM32F103RB6 is a slave. I want to get data of STM6S103 about PWM, sensor data via STM32F103RB6 and display the data via wifi to smartphone. The wifi module is connected to STM32F103RB6. I have no idea how to do that.
