Which is a popular protocol for serial communication in embedded system?

Serial Peripheral Interface, which is commonly known as S-P-I or “spy” is one of the most popular interface specifications used in embedded systems. Since its introduction in the late 1980’s by Motorola, the SPI protocol has been widely used for short distance communication in embedded systems.

What are the commonly preferred communication protocols used in embedded systems?

In this series of articles, we will discuss the basics of the three most common protocols: SPI, I2C and UART. SPI, I2C, and UART are quite a bit slower than protocols like USB, Ethernet, Bluetooth, and Wi-Fi, but they’re a lot simpler and use less hardware and system resources.

What are different protocols used in serial communication?

Similarly there are several examples of Serial Communication Protocols such as CAN, ETHERNET, I2C, SPI, RS232, USB, 1-Wire, and SATA etc. In this article, the different types of Serial Communication Protocols will be discussed.

Why do we prefer serial interface protocols in embedded systems?

For embedded systems that must interface with a general-purpose computer, a serial interface is often easier to use than the ISA or PCI expansion bus. “Memory-mapping” peripherals has been a technique commonly used for systems with address and data buses. This tendency allows parallel access to off-chip peripherals.

What are different modes of communication in embedded system?

Types of Inter System Communication Protocols USB Communication protocols. UART Communication protocols. USART Communication protocols.

What are the embedded protocols?

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 are the limitations of the RS232 protocol?

The limitations of RS232 protocol are, it doesn’t support full-duplex communication and it is a single-ended protocol which shifts the ground potential. Moreover, the longer cable length introduces cross talk during serial communication. Hence, this protocol is restricted for long distance communication.

How is RS-232 used in an embedded system?

Many embedded systems that use the RS-232 bus either interface with PCs or PC peripherals such as modems. Other systems use RS-232 so that bus traffic can be monitored easily with an inexpensive protocol analyzer or a PC equipped with two serial ports.

What kind of communication does a RS-232 bus do?

An RS-232 bus is an unbalanced bus capable of full-duplex communication between two receiver/transmitter pairs, named data terminal equipment (DTE) and data communication equipment (DCE). Each one has a transmit signal that is connected to the receive signal on the other end.

How are serial interfaces used in embedded systems?

Serial buses dot the landscape of embedded design. From displays to storage to peripherals, serial interfaces make communications possible. Many serial communication interfaces compete for use in embedded systems. The right serial interface for your system depends on several key factors.
