Which digital communication is better I2C or SPI?

I2C supports multiple devices on the same bus without any additional select lines (work on the basis of device address). SPI requires additional signal (slave select lines) lines to manage multiple devices on the same bus. I2C is better for long-distance. SPI is better for a short distance.

What is SCL and SDA?

This is just two wires, called SCL and SDA. SCL is the clock line. It is used to synchronize all data transfers over the I2C bus. SDA is the data line. The SCL & SDA lines are connected to all devices on the I2C bus.

Which is faster I2C or UART?

I2C is also generally faster than UART, and can reach speed of up to 3.4 MHz. Some of the disadvantages of I2C include its increasing circuit complexity with additional master/slave setups, and is only able to operate in half-duplex, meaning data can only be transmitted in one direction at a time.

What is 12c draw 12c protocol using bus structure?

I2C Bus Physical layer: But we generally see a single master with multi slave in I2C communication. I2C Bus consists of only two wires and is named serial data line (SDA) and a serial clock line (SCL). At the physical layer, both SCL and SDA lines are of the open-drain design, thus pull-up resistors are needed.

What is the difference between I2C and SPI communication protocol?

The important difference between I2C and SPI ( I2C vs SPI ) communication protocol. I2C can be multi-master and multi-slave, which means there can be more than one master and slave attached to the I2C bus. SPI can be multi-save but does not a multi-master serial protocol, which means there can be only one master attached to the SPI bus.

What is Serial Peripheral Interface?

The serial peripheral interface is four wire-based full-duplex communication protocol these wire generally known as MOSI (master out slave in), MISO (master in slave out), SCL (a serial clock which produces by the master) and SS (slave select line which use to select specific slave during the communication).

What are the different types of communication protocols?

In this series of articles, we will discuss the basics of the three most common protocols: Serial Peripheral Interface (SPI), Inter-Integrated Circuit (I2C), and Universal Asynchronous Receiver/Transmitter (UART) driven communication. First, we’ll begin with some basic concepts about electronic communication, then explain in detail how SPI works.

What are the basic requirements for interfacing of EEPROM with microcontroller?

Basic Requirements for interfacing of EEPROM. Knowledge of I2C protocol. When you want to interface an EEPROM with microcontroller then you need to have a good knowledge of I2C protocol. If you are not aware of the I2C protocol then don’t need to worry, it is a very simple serial communication protocol.
