The thesis examines hardware IoT platforms, surveys existing platforms and designs modular IoT platform consisting of printed-circuit boards interconnected with M2.COM standard. LoRaWAN modem is used for wireless data transfer. External sensors are connected to the device using connector mikroBUS and QWIIC. Whole system is tested by counting pulses from selected water flow-meter.

The content of this work is the design and implementation of HW supported by SW for viewing subtitles into the movie, which translates from the projection equipment on 16 mm film, synchronizing subtitles with the movie, at the same time the work also addresses the issues of principle changes the distance of the canvas. Subtitles are loaded by using the SD card slot control by using the control, which is used to display graphics monochrome buttons that are also used for setting the device and its modifications.

This report details the process of developing libraries to handle data management on two types of non-volatile memory interfacing with an STM32 microprocessor. This was done at the request of Suonobouno AB, who are developing digital and analog synthesizers. This work included the development of generic open-ended memory management functions, as well as functions for handling the specific data structures used in the company's instruments, the later building on the former. In the end, a library was developed that can perform the reading and writing of data to the storage mediums through a clean interface devoid of unnecessary detail. The solution is highly modular, with a clear strategy for managing coupling, to allow the library to grow and develop with further integration. / I denna rapport beskrivs arbetet med att utveckla bibliotek för hantering av externa lagringsenheter som används av en STM32 mikroprocessor. Detta utfördes på uppdrag av Suonobouno AB som utvecklar digitala och analoga syntar. Detta arbete innefattade framtagandet av generiska funktioner för minneshantering, så väl som funktioner anpassade för de specifika datastrukturer som förekommer i det system som är den tilltänkta applikationen. I slutändan åstadkoms ett bibliotek som kan utföra den nödvändiga läsningen och lagringen av data till de två lagringsmedia som omfattades av projektet. Detta kan kontrolleras genom ett rent interface som inte kräver kännedom om tekniska detaljer bakom lagringsteknikerna. Biblioteket är modulärt, med en tydlig strategi för att hantera beroenden, så att det kan växa och utvecklas med vidare integrering.

Η παρούσα διπλωματική εργασία αφορά την μοντελοποίηση και προσομοίωση της συμπεριφοράς ενσύρματων τηλεπικοινωνιακών καναλιών. Αρχικά, αναλύθηκε το θεωρητικό υπόβαθρο των ενσύρματων τηλεπικοινωνιακών καναλιών και αναπτύχθηκαν τα βασικά μοντέλα που υλοποιήθηκαν στην διπλωματική εργασία. Στην συνέχεια, περιγράφηκε η πλατφόρμα ανάπτυξης STM32-H107 όπου πραγματοποιήθηκε η προσομοίωση του συστήματος και αναλύθηκαν τα βασικά περιφερειακά του επεξεργαστή που χρησιμοποιήθηκαν. Στις τελευταίες ενότητες, αναλύθηκαν το γραφικό περιβάλλον του χρήστη, το σύστημα που τρέχει στην πλατφόρμα και η επικοινωνία μεταξύ των δύο, ενώ μετρήθηκε η αξιοπιστία του συστήματος μέσα από μετρήσεις και σύγκριση των επιθυμητών τιμών SNR που εισήγαγε ο χρήστης με αυτές που επιτύγχανε το σύστημα. / This master thesis deals with the modeling and the simulation of wired telecommunication channels’ behavior. Firstly, the theoretical background of wired telecommunication channels was explained and their basic models were developed. Also, the development board STM32-H107, which was used for the simulation of the system, was described, and the basic processor’s peripherals were analyzed. In the final chapters, the graphical user interface and the application which run on the board, as well as their communication, were presented. System’s reliability was evaluated through comparing the real SNR with the desired SNR.

This paper describes the design of Stepper motor controller module controlled over Ethernet for positioning system. Part of this work describes analysis of the assignment, design of modular circuit, choosing right components and prototype design of communication and power module. In another part each module is described with emphasis to modularity. It deals with description of manufactured prototypes and their tested paramethers.

This thesis deals with determine location using very low power consumption device. The main target was to design and construct device using right platform and sensors for localization, sending data using IoT LoRa network and than processing data on server's side. To solve the problem, it was used community network TheThingsNetwork. In thesis I created power efficient device, which can find current location using GPS system and deliver it to user using LoRaWAN network.

The main objective of this work is to inform the reader of the communication protocols Modbus TCP and Modbus RTU and create an embedded device based on the microprocessor STM32 capable of conversion between Modbus RTU and Modbus TCP protocols. The device should be capable of simple first run configuration with simple user interface.

My task was to build a smaller structure triaxial CNC milling. I designed electronics for motion control. The main part is the implementation of the control unit, which will provide control of the machine. The work includes the complete design, PCB design and program description for the uP ARM. The unit can work independently as well as hardware interpolator connected to the PC.

This thesis is about construction of a monitoring unit for motor vehicles. The unit is equipped with microcontroller, graphical LCD for displaying all measured values, GPS module and SD card slot. For measuremet of motor RPM, various methods of connecting to the motor are supported. Temperature is measured with few DS18B20 sensors, picking up engine temp, outsider and inside temp. GPS module is for measuring speed and height above MSL. All measured values can be recorded on SD card for future analysis on PC.

This thesis describes the design and realization of terminal for time attendance system. The introductory part shortly presents several solutions currently available on the market. The main part of this thesis is divided into two sections. The first of them deals with design of hardware platform, and the second describes the development of software. The terminal is realized as a compact with wide possibilities for future functional expansion. Special attention is given to the flexibility and user-friendly interface.
