What are the different protocols involved in networked embedded systems?

Popular communication protocols in Embedded systems – Part I

• SPI(Serial Peripheral Interface) Protocol:
• I2C(Inter-Integrated Circuit) Protocol:
• USART(Universal Synchronous/Asynchronous Receiver/Transmitter) Protocol:
• CAN(Control Area Network) Protocol:
• USB(Universal Serial Bus) Protocol:
• ETHERNET Protocol.

What is the difference between UART and serial?

Simply, a UART is a serial port, but a serial port is not neccessary a UART. Serial port is a general term for anything serial, without further specification, while a UART defines a tranceiver for a specific asynchronus format.

What is the embedded protocol?

Embedded System is an electronic system or device which employs both hardware and software. A processor or controller takes input from the physical world peripherals like sensors, actuators etc., processes the same through appropriate software and provides the desired output.

What are the types of communication protocol?

Types of Communications Internet Protocols (IP)

• Transmission Control Protocol (TCP) – used for data transmission.
• User Datagram Protocol (UDP) – used by programs to send short datagram messages.
• Internet Control Message Protocol (ICMP) – messages used for diagnostic or error-generating purposes.

What is difference between UART and RS232?

Rs232 is just a standard for serial data transmission including voltage levels pin allocation, bit rate etc. A UART is a universal asynchronous receiver transmitter which is used as part of some asynchronous rs232 hardware implementations.

What is the difference between UART and SPI in embedded systems?

When you are dealing with the nuances of getting things to work in an embedded system, this can be easy to overlook. However, UART is an actual piece of hardware (a microchip) while SPI is a protocol or specification for communication.

What is USB communication protocol in embedded systems?

USB (Universal Serial Bus) Protocol: USB is one of the well developed and most used communication protocol. Despite having different standards and hardware types, it is considered to be versatile and effective in embedded systems. USB communication takes place by means of polling where the host device initiates the data transfer.

What are the different types of communication protocols used in microcontrollers?

When we’re talking communication protocols, a UART, SPI and I2C are the common hardware interfaces people use in microcontroller development. This article will compare the various interfaces: UART, SPI and I2C and their differences.

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.
