Η παρούσα διπλωματική εργασία ασχολείται με την μέτρηση της κίνησης ενός αντικειμένου στους τρεις άξονες και ασύρματης μεταφοράς των δεδομένων αυτών σε ένα σταθμό βάσης. Η μέτρηση και μεταφορά γίνεται με χρήση δύο ενσωματομένων συστήματων, τα οποία είναι βασισμένα στην οικογένεια μικροελεγκτών STM32 της εταιρίας ST Microelectronics. Tα συγκεκριμένα σύστηματα εχουν το χαρακτηριστικό STM32-103STK και παρέχονται από την εταιρία Olimex. Αρχικά περιγράφονται τα χαρακτηριστικά και οι ιδιότητες του συγκεκριμένου συστήματος και στη συνέχεια παρουσιάζεται η μεθοδολογία πάνω στην οποία στηρίχθηκε η ανάπτυξη της ενσωματομένης εφαρμογής. Συγκεκριμένα, ο προγραμματισμός του συστήματος προϋποθέτει την συνεχή μέτρηση των τιμών της κίνησης στους τρεις άξονες και στη συνέχεια την ασύρματη αποστολή τους σε ένα δεύτερο σύστημα το οποίο είναι κατάλληλα προγραμματισμένο να δέχεται τα δεδομένα και στη συνέχεια αυτά να εγγράφονται στην οθόνη για να γίνουν ορατά από το χρήστη. / This diploma thesis is about measuring an object’s movement and then the wireless transfer of the measured data to a base station. The measurement and wireless transfer is performed via two embedded systems based on the STM32 microcontroller family by ST Microelectronics. The referenced system is the STM32-103STK provided by Olimex. At the beginning of the thesis there is a description of the main features and characteristics of the STM32 system and then the methodology used to develop the embedded application is presented. In more detail, the system is programmed to measure 3-axis acceleration and send the measured data wirelessly to a second system which then presents the data on an LCD screen.

The thesis is focused on developing a control system for a students project of racing car Falcon with pneumatic propulsion system. The electronic design was splitted into 4 standalone modules to increase reliability and mainain- ablitity of the system. The modules are engine control unit, power supply, human machine interface and speedometer. A CAN bus with customly designed communication protocol is used to interconnect these modules. Except the pneumatic circuit control the elekctronics takes care also about measuring the race related data (pressures in the pneumatic circuit, car speed, etc.). These values are stored on SD card and optionally sent over a wireless link to PC. In the second part of the thesis design of the firmware is described. For the debugging purposes a logging system was developed. The log messages from all modules are sent over CAN and stored on the SD card for post-mortem analysis. Unit tests were written for all elementary software blocks. The Falcon vehicle with this control system participated in the competition organised by the Hungarian company Aventics during May 2019. The Falcon ended on 8th place in long distance race and on 7th place in arcade race.

This master thesis deals with development and construction of ultrasound diagnostical system with USB interface.

Steiger, V. Usage of ARM processors in heating control system. Diploma thesis. Brno: Mendel University, 2016. This thesis aims to simplify the process of controlling heating and cooling systems with standardised, widely accessible computers on purpose of integration into smart home systems. In theoretical part, heating systems available on the market are reviewed, mainly with focus on communication interfaces and protocols in use. Then the specifications of one of the most widely used protocol in heating systems communication OpenTherm, and one of the most widely used protocols in industrial computers communication RS485 Modbus are examined. Theoretical part also contains a description of integrated development environment and platform-specific development properties for STM32 ARM platform. In desing and Implementation is described RS485 Modbus OpenTherm converter firmware written in C language. Behaviour of the converter is then tested in practise.

This thesis deals with designing and implementing autonomous decoder for RTTY communication. Theoretical part of the thesis deals with researching the RTTY technology and FSK modulation, which it uses, focusing mainly on the methods of demodulation. Next part of the thesis compares suitability of available platforms. Practical part of the thesis describes the design and implementation of circuit board, firmware and computer application. The device is using STM32 microcontroller. Firmware was developed in C++ using Arduino. The computer application was created by using C\# and WPF. 3 methods of FSK demodulations were implmented. One is using a FFT algorithm. Other two calculate frequency based on the period of square signal.

This thesis deals with the design and realization of a DC/DC converter, which allows power conversion from 10-52 V input voltage to 10-52 V output voltage at a maximum output current of 3 A. The converter can communicate with the superior system via the CAN. In the first chapter I deal with the available integrated circuits of DC/DC converters, from which I choose one for my application. In the second chapter, I propose a block scheme of the converter, which includes the requirements from the assignment as well as my additional ones. In the third chapter I deal with the design of an electronic circuit and with the calculation of control loops. In the fourth chapter I propose firmware for the STM32 MCU, which controls the device and communicates with the superior system. In the last chapter the DC/DC converter is tested.

The diploma thesis deals with the issue of plasma generators. Specificantlly, the work focuses on the design of HMI devices for plasma generators, including the design of the control part of the generator. The main advantage of controlling the plasma generator using an HMI device is the ability to quickly change important parameters. The HMI device allows convenient switching of the generator output frequency without the need to interfere with the wiring, which leads to higher efficiency when working with the plasma generator. Another advantage of the HMI device is the display of all important information on the LCD display. The work deals with the basic theory of plasma and its use, the division of microcontrollers and the description of their peripherals, the selection of components used and their wiring. The last part of the work is devoted to the software of the plasma generator.
