Mičulka, Lukáš ; Bidlo, Michal (referee) ; Herrman, Tomáš (advisor)
This Bachelor thesis is focused on connection design of information board with LED diode matrix and creation of firmware for 8-bit microcontroller from 8051 family, which aim is to control the matrix and communicate with PC over RS232 interface. Marginally there is mentioned the application for PC, which can handle with text imaging and changing data in memory of microcotroller. Within this thesis there was completed and tested the working prototype of this appliance.

Room Temperature Controller
Hruškovský, Antonín ; Tříska, Vít (referee) ; Mičulka, Lukáš (advisor)
This bachelor thesis deals with a production of a room thermostat for regulation of temperature in a house or flat. The text describes several types of sensors for measuring temperature according to various physical principles. Afterwards, one of the types of sensors has been selected and used in a measuring unit. Subsequently, a hardware design of the thermostat has been described, including the creation of the PCB design on a computer, component selection and the thermostat production itself. This is followed by the description of algorithms implemented on the microcontroller MSP430 to ensure the proper functioning the thermostat. A software has been installed into the side of the computer used to communicate with the thermostat. The communication with the thermostat has been realized by means of an USB bus.

Building Heating System Controller Using Zigbee
Mičulka, Lukáš ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This thesis is focused on the design and implementation of heating controller system of the model house. In terms of design is the emphasis on simplicity, efficiency and scalability. Implemented heating controller system includes a central controller unit and modules that are placed around the model house and can perform several functions - temperature measurement, control actuators or remote parts of the wireless link. This thesis describes the complete development from the initial system design through assembly of all elements of hardware, firmware implementations for each module type and a control program running in the control unit. It also describes the communication between system elements. Suitably chosen solution combines wired and wireless connections, depending on how it is ideal in terms of the model house. The whole system of functional prototypes was tested and the results were summarized in the conclusion.

FPGA-based MP3 player
Náplava, Tomáš ; Mičulka, Lukáš (referee) ; Kaštil, Jan (advisor)
This work deals with the design and implementation of a hardware unit that is capable of playing MPEG-1 Layer III files, compliant with ISO/IEC 11172-3. There are given the benefits of using the MP3 format and principles that make it possible to compress the size of the resulting music recordings. The file format and all parts of the header are thoroughly studied as well as the method of encoding information. The process of the data decoding is divided into several consecutive, more or less discrete functional units and these units are designed and described in a hardware description language VHDL. There are also discussed features of FPGA chips - programmable gate arrays. Those are used for physical realization of the MP3 player. A development board is selected, including such an FPGA chip and other resources that allow synthesis of the entire circuit and playback in real time.

Usage of Modern Methods for Increasing Reliability of Control System Implementations
Szurman, Karel ; Mičulka, Lukáš (referee) ; Kaštil, Jan (advisor)
At avionics control and critical systems is necessary guarantee a minimal level of fault tolerance and their high reliability. On the electronic components in these devices has an undesirable influence environment conditions and mainly cosmic ray. In this paper are described the most common failure types of semiconductor components and devices together with modern methods which can be increased the system fault tolerance and its overall reliability. There are introduced aspects of the avionic systems design due to finally certification and ways to evaluate its safety. This thesis describes design and implementation of the CAN bus control system for the FPGA platform which uses the CANAerospace application protocol. Created system design is improved by the TMR architecture. Fault tolerance of both system version is tested by the SEU framework which allows using the dynamic partial reconfiguration generate an SEU failures into running FPGA design.

Web Portal for Fault Tolerant Methodology Application
Poupě, Petr ; Kaštil, Jan (referee) ; Mičulka, Lukáš (advisor)
This master's thesis deals with the development of web portal for the application of fault-tolerant methodologies. It introduces the issue of fault-tolerant systems and analyze system requirements, that have users working in this field. It describes the development cycle from analysis and specification of application system design through to implementation and testing part. More thoroughly it is focusing above design portal that provides a comprehensive and versatile solution to the problem that leads to the final implementation of this portal. This realization is part of the thesis.

Information Modules Supporting Bluetooth Communication
Knytl, Marek ; Tříska, Vít (referee) ; Mičulka, Lukáš (advisor)
This bachelor thesis describes the creation of two information modules, which are controlled by microcontroller and command using keyboard and display. These devices communicate with server, running on PC, using Bluetooth technology and they are designed for mutual transmission of short text messages. The introduction is devoted to the Bluetooth theory, than goes to the core of this bachelor thesis, which is the design and implementation of information module hardware and its firmware development. Developing server application for the PC is mentioned at the end of this document.
