I2C in STM32 The initialization process for STM32 peripherals is handled by the Cube IDE.The physical I2C bus. This is just two wires, called SCL and SDA. SCL is the clock line. It is used to synchronize all data transfers over the I2C bus. SDA is the data line. The SCL & SDA lines are connected to all devices on the I2C bus. There needs to be a third wire which is just the ground or 0 volts.Clock Stretching. In an I2C communication, the master device determines the clock speed. Unlike RS232 the I2C bus provides an explicit clock signal which relieves master and slave from synchronizing exactly to a predefined baud rate. However, there are situations where an I2C slave is not able to co-operate with the clock speed given by the.Boot and Reset Buttons. In order to upload code to the STM32 MicroMod Processor Board, you'll need these two buttons to put the board into Boot mode.
