Táto práca sa zaoberá vývojom a testovaním konfigurovateľného SPI slave zariadenia, ktorého hlavným účelom je testovanie reálnych SPI master zariadení. Zariadenie je implementované pomocou STM32 mikrokontroléra na vývojovej doske NUCLEO. Medzi základné funkcionality zariadenia patrí meranie frekvencie SPI prenosu, stream mód, ktorý umožní umožní presne sledovať, čo pripojené master zariadenie posiela po SPI zbernici a LUT mód, ktorý umožňuje nakonfigurovať zariadenie tak, aby odpovedalo prednastavenými odpoveďami na aktuálnu príchodziu správu. Rozšírená funkcionalita sa skladá z EEPROM emulátor módu. V tomto móde sa zariadenia správa ako virtuálna náhrada reálneho EEPROM zariadenia. Zariadenie je pripojené k počítaču pomocou sériového portu a je možné toto zariadenie konfigurovať pomocou python programáterského rozhrania. Zariadenie taktiež hlási každú aktivitu na SPI zbernici tomuto python programátorskému rozhraniu.

The goal of diploma thesis is design of programmable control system. This system can be used for regulation of basic parameters in an aquarium. Primary parameters for selection of this device are the price and the easy realization of final device. In first step there are selected parameters, which are needed to control. In second step there is described which kind of sensors can be used for measuring of selected parameters and suitable regulation of necessary parameters. The device is supposed to communicate with PC by USB and this communication is going to be compatible with an old RS-232. Device must be completed with hardware design. Device will be in principle system with real time, that is the reason why device will contain microcomputer. A microcomputer must communicate with other integrated circuit in the device and it supposes to communicate with PC. In specific chapter it will be described, how many different kinds of communication it is possible. For microcontroller it is necessary to create a program, which can figure the measured parameters and it also allows setting up the way how parameters can be regulated. Measured parameters are supposed to storage in the specific memory for the later interpretation. The completely device must be put into a case, which is calculating with a damp place. There must be created a host application for PC. This application suppose to detect if device is connected, figure measured parameters and also allows to set up the way, how to regulate the parameters and display the storages parameters. The application is suppose to run on the operation system created by Microsoft (Windows XP and Windows Vista or later). Diploma thesis contains a problem of the analysis which parameters may be controlled and the way how it can be controlled. There will be selected the sensors, which are suppose to measure and there will be described the basic data transfer and the specifications. It will also contain description of the hardware and software implementation of the device and possibilities of the user’s settings. There will be described the host application and its possibilities. Finally there will be described a functionality of the device and the host application. It will be also imagined some system upgrades for future.

This diploma thesis is about design and realization of universal control unit of technologic processes in food-processing industry. The main goal of this work is to create a device, which will be able with respect to desired values and using measured data autunomusly regulate output. In this work was done the realization of the control unit both from hardware and software aspect. Designed control unit is able to change the output power according to measured temperature. Furthermore is able to control of 2 relays. To set up the desired values and control of relays is used PC software.

Αρχικά εξετάζεται η φυσιολογία της καρδιάς και η λειτουργία της ως αντλίας, οι διάφορες φάσεις του καρδιακού κύκλου και τα αίτια των φαινομένων που παρατηρούνται σε αυτόν. Στη συνέχεια μελετώνται οι καρδιακοί ήχοι, η προέλευσή τους και μέθοδοι παρατήρησής τους, το ηλεκτροκαρδιογράφημα, τα χαρακτηριστικά του και οι εφαρμογές του.

Presented Diploma thesis is aimed on design and implementation of car diagnostic interface of engine control units EDC. Diagnostic interface provide communication between car and computer by USB interface. User will be able to task commands by developed computer application. For developing application is necessary to get information about used protocols and basic knowledge in car’s hardware. Understanding OBD2 standard and communication protocol CAN, eventually KWP is necessary for design the solution. Main purpose of this thesis is to store enough usable information about car diagnostic for future continuation.

This thesis deals with the implementation of a system for measuring the amount of water in the tank using a 12V water pump. The whole system is controlled by the ESP32 microcontroller. The introduction deals with the theoretical analysis of various principles of measuring the level of liquids. The next part deals with the procedure of the construction of the measuring device and its theoretical analysis. The last part of the work deals with the control of the pump and the individual functions that provide this control. The ultrasonic distance sensor AJ-SR04M was chosen for the implementation of the device. The volume of water in the tank is calculated from its data. The ESP32 microcontroller provides system control via a web interface. The whole system was implemented and tested to measure the volume of water and its pumping in the IBC container.

Diploma work deals with industrial display systems, indicators and their proposal. These systems are used everywhere that is necessary to mediate transmission of information. Own proposal of indicator is very specific and depends on given application and used display. In practice there is possible to use a few types of displays but in this diploma work there are used only sedmisegmental and matrix. Common component of proposal is microcontroller. No less significat and important part of the proposal is a choice of interface and communication protocol. The correct choice of hardware that is completed with software we will obtain complete status indicator.
