An overview of the I2C protocol
I2C is another commonly used protocol. Let’s explore what it is, its key features, how it works, and its data format.
What is I2C?
I2C is a multi-master, multi-slave, packet-switched, single-ended, serial communication bus invented by Philips Semiconductor (now NXP Semiconductors). It’s designed for short-distance communication within a single device or between multiple devices on the same board. I2C is known for its simplicity and ease of use, making it a popular choice for communication between microcontrollers and other ICs. Let’s see its key features.
The key features of I2C
I2C has a number of unique features, which makes it ideal for various applications in embedded systems:
- A two-wire interface: I2C uses only two wires, Serial Data (SDA) and Serial Clock (SCL), which simplifies the wiring and reduces the number of pins required on the microcontroller.
- Multi-master and multi-slave: Multiple master devices...
