WebDescription. Driver API for I2C Bus Peripheral (Driver_I2C.h) I 2 C (Inter-Integrated Circuit, referred to as I-squared-C, I-two-C, or IIC) is a multi-master serial single-ended bus and is mostly used on single boards, but can also connect to components which are linked via cable.. Most significant features of the I 2 C bus include:. Only two bus lines are required
Web16 dec. 2024 · I2C is flexible and useful for connecting multiple devices. It allows users to integrate multiple master and slave devices – up to 128 devices on a single bus. I2C also has flow control and performs data validation, so the integrity of the data and how it was transferred is reliable. I2C is also generally faster than UART, and can reach speed ...
