Serial communication protocol

In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus.This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels.. Serial communication is used for all long-haul communication and most computer networks. Before starting with Serial Communication Protocols, Let's break the terminology in three parts. The communication is very well known terminology which involves the exchange of information between two or more mediums. In embedded systems, the communication means the exchange of data between two microcontrollers in the form of bits. This exchange of data bits in microcontrolle

Any communication protocol where devices share a clock signal is known as synchronous. SPI is a synchronous communication protocol. There are also asynchronous methods that don't use a clock signal. For example, in UART communication, both sides are set to a pre-configured baud rate that dictates the speed and timing of data transmission Serial communication initially begins when one device that wishes to communicate sends out data via digital pulses via a serial communication bus (wires) to another device at a rate that the protocol supports. The receiving device picks up the pulses, looking for pulses coming in at the same rate. This type of serial communication is called asynchronous serial communication, where sending and. communication protocols have been designed to achieve data exchange. The most common serial communication protocols are RS232, RS485, RS422, USB, and Ethernet.

Serial communication is a simple means of sending data to long distances quickly and reliably. The most commonly used serial communication method is based on the RS232 standard. In this standard, data are sent over a single line from a transmitting device to a receiving device in bit serial format at a prespecified speed, also known as the Baud rate, or the number of bits sent each second. In RS485 communication protocol, the commands are sent by the node which is defined as a master. All other nodes connected to the master receive the data over RS485 ports. Depending on the information sent, zero or more nodes on the line respond to the master. With that said, this type of communication is not the only possible way to exchange data over RS485 protocol. There are some other.
