  • Unit 4 Part 1: Communications – Serial Protocol
    1300 Henley Court Pullman, WA 99163 509.334.6306 www.store.digilentinc.com Unit 4 Part 1: Communications – Serial Protocol Revised May 23, 2017 This manual applies to Unit 4 Part 1 1 Introduction “Telecommunication is the transmission of signs, signals, writings, images and sounds or intelligence of any nature by wire, radio, optical, or other electromagnetic systems, as defined by the International Telecommunication Union (ITU). Telecommunication occurs when the exchange of information between communication participants includes the use of technology. It is transmitted either electrically over physical media, such as cables, or via electromagnetic radiation. Such transmission paths are often divided into communication channels which afford the advantages of multiplexing. The term is often used in its plural form, telecommunications, because it involves many different technologies.”1 Telecommunications can be divided into two basic types: digital communications and analog communications. Common residential telephone systems as well as AM and FM radio are forms of analog communications. The focus of this unit is digital communication where the information is communicated as encoded discrete level signals. The digital signals can represent computer generated values or be the result of digitization of analog signals. Serial communications involves sending data one bit at a time. This is opposed to parallel communications where multiple bits of data are sent simultaneously, such as the interface with the character LCD that was the focus of Unit 3. One of the biggest motivations for implementing serial communications is to minimize the number of processor pins and wires needed to pass data between two points. The longer the physical distance between these two points (the endpoints), the more expensive the communications media becomes, whether that is wireless or wired based.

What is the highest frequency that can be sampled without aliasing? . 1 Problem 3 20 Points To choose an A/D converter and program it, we need to know the resolution (number of bits), the sampling rate (time between samples) and the number of points to sample (duration of the sampling period). Assume a sensor outputs .05 ◦ ◦ volts/ C with a range of up to 100 C. How many bit A/D converter is needed ◦ to get a resolution of 0.1 C? . Problem 4 20 Points Suppose we wish to compute the Fourier Transform (FFT)of a signal. We choose the sampling rate based on how fast the sampled signal can change and the duration of sampling based on the resolution in frequency. Note that the A/D is normally programmed to sample every Ts seconds and take N samples. Then, NTs determines the period of each frame of sampling and hense the resolution in frequency as ∆f =1/NTs 1.

  • Buses and Networks for Contemporary Avionics by Mike Glass Principal Marketing Engineer Data Device Corporation
    Buses and Networks for Contemporary Avionics By Mike Glass Principal Marketing Engineer Data Device Corporation © SAE 2008 (assigned by Data Device Corporation). The SAE’s policy is not to endorse any service or product. November 2007 Buses and Networks for Contemporary Avionics White Paper Buses and Networks for Contemporary Avionics Abstract MIL-STD-1553 has served the needs of military system integrators for over 30 years, particularly in the area of command and control applications. Nevertheless, contemporary applications such as high-speed digitized sensors, file transfers, processor clusters, and displays require much higher data rates than 1553’s 1Mb/s. For some environments, particularly for legacy aircraft, the optional solution is to transmit faster data rates over existing 1553 buses. However, there are other applications that can accommodate and benefit by the deployment of gigabit or multi-gigabit copper or optical switched fabric networks. In addition to MIL-STD-1553, this paper presents and comments about several avionics networking technologies including High-Speed 1553, Fibre Channel, Gigabit Ethernet, and ARINC 664, a form of profiled Ethernet. Introduction For decades, MIL-STD-1553 has served as the workhorse networking standard for the integration of military/aerospace avionics platforms. However, modern avionics applications provide increasing demands for network bandwidth beyond 1 Mb/s. In addition to 1553’s traditional command and control functions, these applications include processor and DSP clusters, digitized sensor interfacing, displays, file transfers, and data storage. This paper discusses the directions in which military avionics networks are now evolving. One nascent trend is the use of modern telecommunication modulation techniques for providing order(s) of magnitude increase in data rate while leveraging the existing 1553 cable infrastructure.

  • Serial Data Transfer Schemes
    Microprocessors and Microcontrollers P a g e | 1 UNIT-5 SERIAL DATA TRANSFER SCHEMES SERIAL COMMUNICATION INTRODUCTION Serial communication is common method of transmitting data between a computer and a peripheral device such as a programmable instrument or even another computer. Serial communication transmits data one bit at a time, sequentially, over a single communication line to a receiver. Serial is also a most popular communication protocol that is used by many devices for instrumentation. This method is used when data transfer rates are very low or the data must be transferred over long distances and also where the cost of cable and synchronization difficulties makes parallel communication impractical. Serial communication is popular because most computers have one or more serial ports, so no extra hardware is needed other than a cable to connect the instrument to the computer or two computers together. SERIAL AND PARALLEL TRANSMISSION Let us now try to have a comparative study on parallel and serial communications to understand the differences and advantages & disadvantages of both in detail. We know that parallel ports are typically used to connect a PC to a printer and are rarely used for other connections. A parallel port sends and receives data eight bits at a time over eight separate wires or lines. This allows data to be transferred very quickly. However, the setup looks more bulky because of the number of individual wires it must contain. But, in the case of a serial communication, as stated earlier, a serial port sends and receives data, one bit at a time over one wire.
