I2c vs uart performance










UART, or Universal Asynchronous Receiver/ Transmitter, is a physical circuit in a microcontroller or single integrated circuit (IC) that is used to implement serial communication between devices in an embedded system. Common I2C applications can include reading memory, reading hardware sensors, and accessing DACs and ADCs. What applications use I2C? I2C is a suitable protocol for connecting short-distanced, low-speed peripherals on printed circuit boards (PCBs). By using the unique address, the master device is able to signal its read/write command to exchange communication between the two over the bus. Because all communication takes place on only two wires, all devices must have a unique address to identify it on the bus. A microcontroller is often used as the master device, and other peripheral devices are used as slave devices.

I2C is used to connect devices like microcontrollers, EEPROMs, I/O interfaces, and other peripheral devices in an embedded system. It is a bidirectional two-wire serial bus that uses serial clock (SCL) and serial data (SDA) wires to send and manage data between devices connected to the bus.īecause I2C operates using a serial clock, it considered to be synchronous, which allows the output of bits to be synchronized to the sampling of bits by a clock signal shared between the master and the slave. I2C, or Inter-Integrated Circuit, is a communication protocol often used in embedded systems as a way to transfer data between a master (or multiple masters) and a single slave (or multiple slaves) device. In this article, we’ll cover the basics of I2C and UART communication, and the differences between them.

Both are often used for similar objectives, but do have some notable similarities and differences.

There are multiple forms of communication that can be used in an embedded system, including a communication protocol, such as I2C, or through a physical circuit like UART. They are what governs how data is sent over the bus, including whether data is sent serially, parallelly, asynchronously, or through a master/slave paradigm. Communication protocols are some of the essential building blocks of an embedded system.
