What is I2C?

I2C (Inter-Integrated Circuit) is a serial communication protocol used to connect low-speed peripherals to a microcontroller or microprocessor. It uses two wires, SDA (Serial Data) and SCL (Serial Clock), to transmit data between devices. It is commonly used for communication between microcontrollers and sensors, memory chips, and other integrated circuits on a printed circuit board.

I2C Complementary Technologies

GPIO

GPIO pins are general-purpose input/output pins that can be used to control or monitor digital signals. I2C communication is often controlled or monitored using GPIO pins for tasks like address selection or interrupt handling. Thus, GPIOs complement I2C.
