Ultrasonic distance measurement
Klich, Michal ; Krajsa, Ondřej (referee) ; Lattenberg, Ivo (advisor)
The aim of this bachelor thesis is the design and manufacture of a controlling program of equipment for distance measurement using ultrasonic sensors. It focuses on a detailed description of the whole design from the basic properties of the components to the creation of schemes and PCB design. It subsequently describes in detail the development of controlling software of the equipment. The work briefly describes the most important parts of the code. It summarizes all theoretical and practical knowledge gained during the creation of the whole design, it explains the principles of the functions and works of individual parts and it suggests the best possible options of connection of the whole equipment. It also suggests the best possible variants of the entire circuit. The bachelor thesis also describes the microprocesor AVR ATmega8 from the Atmel Corporaton, which controls the entire device, as well as EEPROM memory chip 24LCXXX, SRF05 ultrasonic sensor and communication with the PC via USB using a microchip FT230XS-R.

Embedded System with Communication Interface NFC and Wi-Fi
Bugár, Loránt ; Valach, Soběslav (referee) ; Horák, Karel (advisor)
This master’s thesis deals with communication system design via the NFC and Wi-Fi interface. The thesis has two basic goals. The first goal is to create a device that is capable of storing of data and its subsequent transfer via the NFC interface. The second aim is to utilize this device for measuring various physical variables. The IoT technology is employed to fulfill the aforementioned goal. IoT technology is capable of visualizing data in real time and make them accessible via the Internet. The result of this work is an universal device, that contains the most popular communication interfaces, such as I2C, SPI and that is capable of processing measurement data from digital, analogue, and wireless sensors.

Generic logic analyzer
Tajč, Martin ; Povalač, Karel (referee) ; Kubíček, Michal (advisor)
The aim of the project is to design a generic logic analyzer based on an FPGA. The analyzer should be able to analyze protocols such as I2C, SPI, RS232, RS485 and GPIO. The captured data can be observed using an embedded graphical display or using a PC. The PC can be used to control the analyzer and to save the captured data. The thesis is divided into several parts. First, the basic structure of the analyzer is described including detailed description of its particular components. Later on, the most common protocols that can be decoded using the analyzer are described. Finally, the FPGA subsystem and microcontroller application are presented together with corresponding source codes.

Firmware for Testing Platform JaQT
Veverka, Jiří ; Drahanský, Martin (referee) ; Malaník, Petr (advisor)
This bachelor thesis is about the JaQT (Just a Quick Test) platform which was developed for simple and fast software-hardware testing. The theoretical part of this thesis is describing used MCU, control board, peripherals and interfaces. The USB protocol and its CDC ACM class which is used for interfacing the device to enable communication with the board is described in this part as well. In the practical part is described how the JaQT was implemented, debugged, tested, used and evaluated.

Industrial state indicator
Růžička, Zdenek ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
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.

Telepresence Autonomous Robot for Exploration of Unapproachable Areas
Krkavec, Martin ; Janoušek, Vladimír (referee) ; Rozman, Jaroslav (advisor)
The subject of this master's thesis was to get familiar with a robot developed at the Department of Intelligent Systems of FIT VUT Brno. The goal of this work was to design and then implement hardware and software improvements of the robot so it could be capable of telepresence exploration of a narrow cave using remote control, including autonomous return back to the entrance. Also suggest possible extensions for a further improvement of the robot.

Microprocessor-controlled autonomous source of constant current and voltage
Kováč, Marek ; Lattenberg, Ivo (referee) ; Pavelka, Ondřej (advisor)
The task of bachelor thesis is proposal of switching source for the construction of leadacid battery charger 6/12V controlled by microprocessor. It is based on buck converter of voltage. The first part presents the activity of converter and properties of lead-acid batteries, followed by a proposal of converter for a given application. The second part describes a criteria for selection of individual components and dimensioning them. The result of this thesis is simulation of converter in PC program Micro-Cap 9, along with the necessary calculations, a proposal of circuit with the calculation of inductor and methods of measurement of output quantities. Finally, is realized circuit board with a couple measurements and control program for the microcontroller. The entire proposal is focused to achieving the greatest simplicity of facility and efficiency and quality of charging accumulators together at low cost to the product.

Analog input device for industrial automation
Nekovařík, Jakub ; Šír, Michal (referee) ; Bradáč, Zdeněk (advisor)
The main subject of this bachelor thesis are design and implementation of the device, which is used to convert digital values to analog output value in the range 0-10V. This actual trasformation arises in electrical component called Digital-to-Analog Converter. There is a separate chapter, which presents theory and problems of varios types of converts. The following chapters theoretically analyse design of each parts of the device. The conclusion of this thesis deals with specific proposals of used electrical components and a description of the software equipment.
