FlexRay can handle any type of network configuration, it is 10 times faster than CAN, however it is more expensive, hence it is highly suited to high-performance power train, drive-by-wire, active suspension and adaptive cruise control systems. Example of routing protocols includes OSPF, RIP, EIGRP and IS-IS.

Here we go with the basic networking questions and answers. Q) SPI has a higher throughput than I2C – True / False? You can see this article, Difference between I2c and SPI. Guest Article Every FlexRay node is synchronized to the same clock, and each nodes waits for its turn to write on the bus. There are four main parts to a communication cycle: Figure 1: Communication Cycle 1. Q) How many wires are required for SPI communication? Question5: What is the difference between Datacom testing and Telecom testing? 08. I have got the response to create a list of interview questions on the “SPI Protocol”. Question2: What is Protocol testing? If you know the answer, then please write in comment box or email me directly. In the case of asynchronous serial communication, every byte consists of a start and stop bits which create extra overhead on communication. Explain Transmission Control Protocol, TCP. An electrical single wire is used in the LIN protocol.

Q) How to set SPI bus speed in the master device? Higher data transfer rate than I2C (almost twice as fast). Previously I have created a list of “embedded c interview questions” that is liked by many people. The FlexRay bus protocol is an in-vehicle network on its way to the starting line providing large transmission bandwidth for fast control systems. Q1. Q) What is the difference between SPI and I2C (I2C vs SPI)? Dynamic Segment The dynamic segment behaves in a fashion similar to CAN and is used for a wider variety of event-based data that do… Every writes there is dummy read and every read there is dummy write. No need for precision oscillators in slave devices as it uses a master’s clock. Q) What are the limitations of the SPI interface? Q) Can devices be added and removed while the system is running (Hot swapping) in I2C and SPI? The duration of a cycle is fixed when the network is designed, but is typically around 1-5 ms. Answer: Network is defined as a set of devices connected to each other using a physical transmission medium. Tutorials Point Interview Questions and Answers for freshers and experienced pdf. Your effort will be helpful to others. (An Important Networking Interview Questions) EIGRP Interview Question with detailed Answers A researcher’s interview protocol is an instrument of inquiry—asking questions for specific information related to the aims of a study (Patton, 2015) as well as an instrument for conversation about a particular topic (i.e., someone’s life or certain ideas and experiences). 1) What is a Link? Enter your email address to follow this blog and receive notifications of new posts by email. Unlike the serial com port, SPI is the synchronous communication protocol. Blog Posts The SPI bus specifies four logic signals: SCLK: Serial Clock (It is produced by the master to start the communication), MOSI: Master Out, Slave In (This line is used to carry data from the master to the slave), MISO: Master in, Slave out (This line is used to carry the data from the slave to the master), SS: Slave Select (This line is used to select the slave in case of the multi-slave communication). Study these Interview MCQ Questions and Answers on 2G/3G GPRS Architecture Interfaces and Protocols. If a node uses in one FlexRay cycle, other nodes cannot use the same index in following cycles. Networking Interview Questions. About Q) Does the clock stretching support by SPI? CAN INTERVIEW QUESTIONS: 1. Routing protocols define the path for forwarding packets; they find the best path for each destination using different programming algorithms. But I cn sure provide you some very basic information about CAN if it would support your interview. Difference between UART and USART(UART vs USART), How to get com port properties in windows using the Win32 API, 8051 Microcontroller Interview Questions and Answers, Difference between RS232 and RS485 (RS232 vs RS485), C Interview Questions for Experienced with Answer, C program to convert Hexadecimal to Decimal. Ethernet may replace FlexRay for bandwidth intensive, non-safety critical applications. 1. affiliate-disclosure The FlexRay communication cycleis the fundamental element of the media-access scheme within FlexRay. the protocol interview questions are providing them soon as threshold values the thing that ensures that it will always a controller. Basic characteristics of the FlexRay protocol are: Synchronous and asynchronous frame transfer Here data is transferring to the slave using the MOSI bus and at the same time receiving the dummy data from the MISO bus and vice versa. I have got the response to create a list of interview questions on “CAN Protocol”. Both protocols help in to establish the connection and transfer data between two ends of the communication. Q19. The following advice is adapted from both lectures and our work with students as we guide them through both writing dynamic interview protocols and conducting interviews. Interview questions on bitwise operators in C. 10 questions about dynamic memory allocation. Top Networking Interview Questions. Q – 1 Wh a t are your salary expectations as Protocol Officer?. A FlexRay cluster is set of nodes (ECU’s) which communicate to each other over a fixed baud rate. Introduction of SPI communication protocol. If you are looking for “can protocol interview questions” or “can protocol basics, then you are at right place. FlexRay in theory and practice: This workshop teaches you the fundamentals of the time-triggered bus system FlexRay. FlexRay is much faster and more reliable than existing CAN systems, it is also a deterministic system, which gives high reliability of communications. A wakeup symbol is composed of n bits that are transmitted at a LOW level followed by m If there is more than one slave in communication then the wiring will be complex. Here we focus on the writing of an interview protocol to gain in­depth information from users, stakeholders, or experts to guide design decisions. Interfacing EEPROM with 8051 Microcontroller – I2C Based. Q20. I am an embedded c software engineer and a corporate trainer, currently, I am working as senior software engineer in a largest Software consulting company . FlexRay can be used as the bus protocol for highly advanced vehicle technologies, requiring absolute reliability, such as drive-b… If a node is attached to a single channel it does not matter if it is channel A or channel B.
