Overview:The I2C communication interface is the most commonly used MCU peripheral in our daily applications. Initially, before the MCU had hardware I2C, I2C communication was achieved by simulating the I2C timing through GPIO ports. Later, with the introduction of hardware I2C peripheral interfaces in MCUs, the use of hardware I2C became commonplace. More importantly, it … Read more
