In receiver side, the data is being extract using the clock provided by the transmitter and converts the serial data back to the parallel form. In transmitter side, there is a shift of the data onto serial line providing the clock as a separate signal as there is no start, stop and parity bits are added to data. Also there is no mismatch in baud rate in this interface. The data transmission becomes faster with same bus to share clock and data. In this type of interface, all the devices use single CPU bus to share data and clock. It is a point-to-point connection from a master to slave. Synchronous Serial Interface and Asynchronous Serial Interface. The clock is different for serial devices and it is classified in two type viz. So, the clock synchronisation becomes very important when using serial communication. Malfunction of the clock results in unexpected data transmission even sometimes data loss. The well-known example is mobile phone.Īpart from this, for appropriate data transmission, the clock plays important role and it is one of the primary source.
#SERIAL COMMUNICATION PROTOCOL TYPES FULL#
In full duplex method, both receiver and transmitter can send data to each other at the same time. The well-known examples of the half duplex is the internet where the user sends a request for a data and the gets it from server. So if the sender is transmitting then receiver can accept but cannot send and similarly vice versa. In half duplex method both sender and receiver can be active but not at the same time. The well-known examples of simplex method are Television and Radio. So simplex method is one-way communication technique. So if the sender is transmitting the data then receiver can only accept and vice versa. In simplex method either of the medium i.e sender or receiver can be active at a time. The transmission modes are classified as Simplex, Half Duplex and Full Duplex. There are several types of serial communication depending on the type of transmission mode and data transfer. binary pulses and it is well known that, binary one represents the logic HIGH and zero represents the logic LOW. Transmission Modes in Serial CommunicationĪs already said above that in serial communication data is sent in the form of bits i.e. The protocol is the secure and reliable form of communication having a set of rules addressed by the source host (sender) and destination host (receiver) similar to parallel communication. Every electronics device whether it is Personal Computer (PC) or Mobile runs on serial communication.
Serial communication is the most widely used approach to transfer information between data processing peripherals. In this article, the different types of Serial Communication Protocols will be discussed. Similarly there are several examples of Serial Communication Protocols such as CAN, ETHERNET, I2C, SPI, RS232, USB, 1-Wire, and SATA etc.
Examples of Parallel Communication Protocols are ISA, ATA, SCSI, PCI and IEEE-488. Similarly the protocols are divided into two types such as Serial Communication Protocol and Parallel Communication Protocols.
There are different types of data transfer available in the digital electronics such as serial communication and parallel communication. More specifically, the data bits are transmitted one at a time in sequential manner over the data bus or communication channel in Serial Communication. one after the other then the communication protocol is known as Serial Communication Protocol. This exchange of data bits in microcontroller is done by some set of defined rules known as communication protocols. In embedded systems, the communication means the exchange of data between two microcontrollers in the form of bits. The communication is very well known terminology which involves the exchange of information between two or more mediums. Before starting with Serial Communication Protocols, Let’s break the terminology in three parts.
