Full textAbstract:
The emerging technology of active RFID tags has strong potential in the areas of real time health monitoring, sorting of cargo, and large scale inventory management because of their longer communication range and larger data storage capacity. The market of active RFID is growing very rapidly and therefore there has been an increase in the number of companies engaging in this field. But very often it is found that the products available in the market are not always suited to the application at hand. To overcome this problem, off the shelf active RFID products which were reconfigurable and followed a standard PHY and MAC layer protocol were used for this work. By reprogramming the application layer protocol of the RFID hardware, these devices were made suitable for the desired application. This also allowed the RFID tags to extend their functionality by interfacing extra modules with themselves. The work presented in this thesis describes the way in which the microcontroller on board the active RFID tags and readers can be programmed so that the functionality of the RFID hardware can be changed as per requirements. It also shows that extra modules can be added to the tag by successfully interfacing an accelerometer module with the tag.Master of Science

Full textAbstract:
Legacy computer systems are systems where several of the main hardware and software components date back several decades. Modernizing these systems is often considered a large monetary and temporal investment with high risk, and to keep maintaining them usually becomes more and more difficult over time, which is why these legacy systems are still being used to this day in many industry sectors. A solution is therefore to try and integrate the legacy system components into modern systems, and there are several ways of achieving this. This bachelor thesis project work aims to analyze one approach known as “wrapping”. More specifically it analyzes NESizer2 Method, a method which utilizes relatively simple hardware and software interfaces to control the Ricoh RP2A03 processor found in the Nintendo Entertainment System, using an Atmega328 microprocessor. During the design and development phases of the project work a literature study was conducted, and experimental research method was utilized. The testing and experimental phases of the project work was focused on examining how identified key variables behaved when modifying certain parameters in the system. While we were able to produce some valid data, the results proved to be somewhat inconclusive, as certain operations such as memory operations did not work, leading to the conclusion that our circuit contained a faulty component.Legacydatorsystem är system där många av de huvudsakliga hårdvaruoch mjukvarukomponenterna är flera decennier gamla. Att modernisera dessa system ses ofta som en stor monetär och tidsmässig investering, och att fortsätta att underhålla dem blir vanligtvis svårare och svårare med tiden. En lösning är därför att försöka att integrera legacy-systemets komponenter i moderna system, och det finns ett flertal tillvägagångssätt att uppnå detta. Detta kandidatexamensarbete ämnar att analysera ett tillvägagångssätt känt som “wrapping”. Mer specifikt analyseras NESizer2-metoden, en metod som utnyttjar relativt enkla hårdvaruoch mjukvarugränssnitt till att kontrollera Ricoh 2A03-processorn som finns i Nintendo Entertainment System, med hjälp av en Atmega328 mikroprocessor. Under designoch utvecklingsfaserna av projektarbetet utfördes en litteraturstudie, och experimentiell forskningsmetod användes. Testoch experimentfaserna av projektarbetet fokuserade på att undersöka hur identifierade nyckelvariabled betedde säg då man modifierade vissa parametrar i systemet. Även om vi lyckades producera en del riktig data visade sig resultaten vara ofullständiga, då vissa operationer såsom minnesoperationer inte fungerade, vilket ledde till slutsatsen att vår krets innehöll en defekt komponent.

Full textAbstract:
Control applications are used in almost all scientific domains and are subject to timing constraints. Moreover, different applications can run on the same platform which leads to even more complex timing behaviors. However, some of the timing issues are not always considered in the implementation of such applications, and this can make the system fail. In this thesis, the timing issues are considered, i.e., the problem of non-constant delay in the control of an inverted pendulum with a real-time kernel running on an ATmega328p micro-controller. The study shows that control performance is affected by this problem. In addition, the thesis, reports the adaptation of an existing real-time kernel based on an EDF (Earliest Deadline First) scheduling policy, to the architecture of the ATmega328p. Moreover, the new approach of a server-based kernel is implemented in this thesis, still on the same Atmel micro-controller.

Full textAbstract:
Upcycling can be described as an activity where outdated or discarded products are used as raw-materials in the construction of a new object, for which an increased quality or value is achieved. Some ideas for upcycling of technologically simple products have prooved successful, in the sense that those ideas have become widespread and practically implemented within a certain target audience. This thesis explores how an idea concerning upcycling of an electric product can be developed into a prototype, with the intent to simplify application of the idea within the target audience of electronic hobbyists. This is achieved through the development of a prototype for an adapter, the purpose of which is to extend the functionality of a character based LCD module with the Hitachi HD44780 control circuit. This allows for using such LCD module for displaying text in additional languages, and (for certain applications) using it as a substitute for a monochromatic graphical LCD module. The conclusion of the study is that the adapter prototype is capable of increasing the number of user defined characters that can be displayed simeltanously by a character LCD module, and that the prototype may be of use for certain types of applications within the intended target audience."Upcycling" kan beskrivas som en syssla där föråldrade eller kasserade produkter används som material vid tillverkning av ett nytt föremål, vilket har högre kvalitet eller värde. Det finns exempel på idéer för "upcycling" av teknologiskt enkla produkter vilka har visat sig framgångsrika, i bemärkelsen att de har nått spridning och tillämpas praktiskt inom någon målgrupp. I detta arbete undersöks hur en idé för "upcycling" av en elektrisk produkt kan utvecklas till en prototyp, med syftet att underlätta tillämpning av denna idé inom målgruppen elektronikhobbyister. Detta sker genom utveckling av en prototyp till en adapter, som utökar funktionaliteten hos en teckendisplaymodul med styrkretsen Hitachi HD44780. Adapterns funktion är att öka det antal användardefinierade tecken som kan visas på en sådan teckendisplaymodul. Detta möjliggör att teckendisplaymodulen kan användas för att visa text på fler språk, och att den för vissa ändamål kan användas som substitut för en monokrom grafisk displaymodul. Slutsatsen av arbetet är att prototypen av denna adapter kan användas för att öka det antal användardefinierade tecken som samtidigt kan visas på en teckendisplaymodul, samt att prototypen kan vara användbar för vissa syften inom den avsedda målgruppen.

The aim of this master thesis is to propose a system for monitoring and regulating the climate in groups of terrariums using the Raspberry Pi platform and subsequent transparent display through the web server. Each group of terrariums has its own control device that wirelessly communicates with the Raspberry Pi control computer. The measured values are stored in the MySQL database on the control computer. The measured values are graphically displayed on the web page.

The Sensor Integration Kit was applied to connect the system and the sensors in the way which was simplified on the wiring system by RJ45 and the Program Puzzle was designed to use the expansions of mBlock for automatic puzzle build-up. The mBlock was used as the system programming tool to form the puzzle program by the integration programs of JavaScrip and S2E, which integrated 7 different sensors and electronic devices such as super-sonic, buzzer, motor, line sensor, flame sensor, sound sensor and LED lights for further applications by the integrated Puzzle Program and Sensor Circuit. The platform designed in this study is specifically suitable for education units on further control of devices for projects and is able to combine the other sensors for the more complicated data analysis and the extra sensor applications.

O presente documento relata o trabalho desenvolvido, no âmbito do estágio
curricular que frequentei durante o presente ano letivo. Estando a entidade
acolhedora inserida no ramo do Controlo de Acessos, o desafio que me foi
lançado, consistiu no projeto de um circuito eletrónico, com capacidade de
abrir remotamente os equipamentos da empresa, através da tecnologia de
comunicação LoRa.
Para além do circuito, foi também definido como requisito, a criação de uma
interface gráfica, onde o utilizador possa tirar partido da solução desenvolvida,
em termos de hardware.
Sendo assim, este relatório de estágio, descreve as várias fases do trabalho
desenvolvido, nomeadamente, a definição dos requisitos do sistema, tanto
a nível do hardware como do software/firmware, a apresentação do estudo
realizado sobre a comunicação LoRa, incluindo o seu principio de funcionamento,
as suas características, as suas mais-valias e limitações, bem como
as principais áreas de aplicação e finalmente, a descrição mais detalhada da
solução desenvolvida.
Desta forma, pretende-se descrever, com o detalhe possível, todo o trabalho
realizado ao longo de seis meses de estágio.This document reports the work developed within the scope of the curricular internship which I attended during this school year. As the company is part of the Access Control business, the challenge that was set for me was the design of an electronic circuit, with the ability to remotely open the company’s equipment, through the LoRa communication protocol. In addition to the circuit, the creation of a graphical interface was also defined as a requirement, where the user can take advantage of the developed solution, in terms of hardware. Therefore, this internship report describes the various phases of the developed work, namely, the definition of the system requirements, both at the hardware and software/firmware level, the presentation of the study carried out on the LoRa communication, including its working principle, its characteristics, its strengths and limitations, as well as the main areas of application and finally, a more detailed description of the developed solution. Thus, it is intended to describe, with as much detail as possible, all the work carried out over the six months of the internship.

In recent years, semiconductor technology has been evolving very quickly. The channel lengths of semiconductor devices have been in the nanometer scale for a long time. The miniaturization of the semiconductor devices can indeed enhance the efficiency of an integrated circuit (IC). However, accompanying with the advances in IC technology are some important issues that remain to be coped with,such as signal integrity (SI) and electromagnetic compatibility (EMC). During this study, I requested Huang-Chin Technology Inc. to fabricate Atmel 8-bit microcontroller test circuit boards for me and asked ATM Electronic Technology Inc. to write the relevant drivers for the microcontrollers in order to carry out EMC measurement. The clock signals generated by the test circuit board can be adjusted by changing the relevant parameters needed by the drivers. The signals radiated from the circuit board were measured using a transverse electromagnetic cell (TEM cell) and a near-field probe, and were simulated using an IC-EMC software tool developed by Institute National des Sciences Appliquees (INSA) in France. Since the fabricated hardware only functioned partially and since this is the last year (four years in total) allowed for my master program, measured and simulated results, which although had the same trend but seemingly did not agree with each other well enough, were separately presented without comparison.

Para este efeito, foi elaborado um módulo de pesagem possível de ser compar
ável com os módulos anteriormente concebidos pela empresa e, consequentemente,
testado e usado em condições semelhantes.
A par do módulo, foi elaborado software, de modo a facilitar uma futura
implementação do mesmo numa pesadora não combinatória e num calibrador

na indústria modernaIt is considered that the present thesis did not focus on a single problem, but rather on improving or reducing the cost of manufacturing of existing machines, already manufactured by the company MCM-eletronic solutions, with a view to designing a new one, with the material that was developed in partnership with the company. For this purpose, a weighing module has been developed which is comparable to previous modules designed by the company and, therefore, tested and used in similar circumstances. At the same time, there was an attempt to add some kind of innovation to the existing material, including wireless communications and adding possibilities in the eld of accessibility, trying to present an innovative but also standardized solution with methods used in modern industry

Full textAbstract:
This thesis is based on the design and production of teaching kits with expansion modules which are based on the Atmel AVR microcontroller. Kit consists of a plate containing processes and basic power modules directly on the board and expansion modules "SIMAČ". "SIMAČ" modules are virtual elements that simulate the real elements and they are commonly used in industrial automation. Because of their cost they are integrated in extension kit as programmable modules. It also contains basic theoretical information about working with ATMEL AVR microcontrollers. Expansion modules with module development board and disc which will be loaded all the schemes, programs and technical documentation for individual districts will be attached to the thesis.
