Implementation of a Serial Communication Interface for a Signal ProcessorEriksson, Jens, Nilsson, Kristian January 2003 (has links)
<p>The purpose of this thesis was to implement a serial communication port model for a digital signal processor. It is a behavioral model, developed using VHDL, that is instruction comparisable to the Motorola digital signal processor DSP 56002. It supports five different data transfer modes and provides a programmable baud rate generator. </p><p>This report starts out by giving a description of the external port, port C, the pin control logic and general purpose functionality. Then a more detailed description of the three pin dedicated serial communication interface is presented, the different operating modes and the baud rate generator are described.</p>

Design and Implementation of a Security Mechanism for SmartcardYang, Shih-Sian 28 August 2009 (has links)
In this thesis, we used a encryption mechanism based on AES(Advenced Encryption Standard). Except for this mechanism, we also combine RS-232 Serial Communication Control, Smartcard and EM card which originally used in the Entrance Guard System to implement a new system. Eventually, this new system applies to a certain rental system practically. We also introduce some functions of this rental system based on the encryption mechanism, station initialization, bike rental, bike allocation and bike rental for credit card for example. In addition, we will describe what problems we met and the solutions we introduced to the problems finally.

Termoregulační zařízení - návrh, konstrukce a měření / Thermoregulation device - design, construction and measurementKOUDELA, Zdeněk January 2019 (has links)
This master's thesis is aimed at development and realisation of a thermoregulation control unit with applications at school and in practice. The work briefly introduces the reader into the principles of electronic temperature measuring in practice and peripheral interconnection of Arduino platform using different types of serial communication. The main part of the thesis is the creation of the control unit itself and its subsequent application for school and laboratory purposes. The work contains several example laboratory tasks, which can fully utilise the potential of the constructed device.

Microcontroller-based Multiport Communication System For Digital Electricity MetersBestepe, Firat 01 December 2004 (has links) (PDF)
This thesis explains the design of a microcontroller-based device, which provides an efficient and practical alternative for the remote reading of digital electricity meters over Public Switch Telephone Network (PSTN). As an alternative application, a system is constructed providing file transfer capability to the PC connected to the port of implemented device in addition to remote reading of digital electricity meters. This thesis also provides detailed explanations about
the basics of serial asynchronous communication over modem for PICs (peripheral interface controllers) together with description of each component included by the constructed system, which can be used in energy metering sector commonly.

Evaluation and Measurement of IoT GatewaysLiu, Yilin January 2017 (has links)
With the vigorous development of Internet of things, IoT gateways as the communication bridge of the whole IoT system has attracted more and more people’s attention. So the objective of this project is to measure and evaluate the performance of two kinds of IoT gateways including Arduino Uno and Vinnter IoT gateway. In order to reach this objective, the concrete implementation is to create a demonstrator via JAVA program to establish serial communication and measure the latency and throughput of respective IoT gateways. The measurement is implemented under a specific scenario which is to control the action of an actuator such as a LED connecting with IoT gateways via GPIO pins. Finally, the results will be presented via statistical data and line charts. Through analyzing the results, the performance of these two IoT gateways can be compared in terms of latency and throughput easily. Besides implementing the measurement in practice, this paper also involves the scientific research of many different industrial-level IoT gateways and their performance are compared on both hardware and software sides. Consequently, this thesis will show you the comparison of various IoT gateways both in theory and in practice.

Connecting Arduino Sensors to SensibleThingsGuan, Xiao January 2016 (has links)
The Internet of Things is going to bring the Internet into every objectsaround us. To enable this ambitious idea, tiny devices have to be connected within the global Internet. Such devices are extreme small so it’sbecoming a challenge to connect it to the Internet via TCP/IP. The thesispresents a way of connecting microcontrollers with other devices to jointlyform a distributed network.The thesis investigates and takes advantage of Internet of Things platform to implement the connection. SensibleThings is used as the platform. Limited by the hardware, microcontroller can’t run such a bloatedplatform. The thesis investigates different microcontrollers characteristics and chooses Arduino as a representative in the work. Then it realizes a bridge connection between Arduino and SensibleThings. Arduinois connected with a single-board computer, Raspberry Pi by a USB cable.SensibleThings is running on Raspberry Pi to process the network messages. The channel throughput, latency and general usability are measured and interoperated. As a result, the data indicates this is a promising, flexible, cost effective network topology. Microcontroller can join adistributed network by the bridge. Comparing to dedicate hardware solution, the bridge connection cuts down the implementation difficultiesand cost. The thesis also covers possible problems in such connection andproposes future work.

Jednosměrná sériová komunikace laserem na větší vzdálenost / One-way serial laser communication over longer distancesValent, Adam January 2021 (has links)
The subject of this thesis is the construction of one-way communication device. This device consists of the transmitter and the receiver, both of which are connected to its respective computer via USB interface. This device allows sending UTF-8 characters or files from one computer to another. Both computers are running a graphical user interface program. The core of a transmitter is a digital signal modulating laser diode. The receiver is made of photovoltaic panel with a resonance circuit and an amplifier. Communication between the electronics and the computer is driven by microcontrollers. Received messages are verified with one of multiple error detection algorithms, which can be selected by user in the utility program.

Zařízení pro monitorování sériové komunikace / System for Serial Communication MonitoringPerný, Jan January 2008 (has links)
There is a need for a serial communication testing tool when software or hardware developers have to solve serial communication problems. This tool must accurately catch and record the whole communication. Some type of timestamps in the record is necessary for future analysis. This diploma thesis deals with programming a serial communication monitoring equipment software with the possibility of the insertion of timestamps. Possible timestamps types and inserting methods are also discussed. The programmed monitoring software for the FOX Board hardware platform is able to catch and record the serial communication at RS232 ports and add timestamps to the record in accordance to three independent rules. The record is saved to a standard USB flash drive.
