Design and realization of a developement board for BeagleBoard
Ťapucha, Andrej ; Hanák, Pavel (referee) ; Krajsa, Ondřej (advisor)
Contents of the thesis is to design and create an expansion board for the BeagleBoard computer one plate . The first and very important part was to find out all the possibilities for an extension of the computer itself . Choose the right expansion port . To study the possibility distribution of individual pins . Followed by the appropriate extension election districts that demonstrate the function of each enlargement . Test was designed PCB that contains circuits that change the voltage level of the BeagleBoard to protect a mini computer to the testing of each gusset periphery prevent damage to itself or part of the BeagleBoard . The peripherals themselves bind different parts of theoretical introduction. More specifically the extension of the LCD display is selected segment and includes two lines of 16 characters . When the possibility to add additional components were necessary to deal with the shortcomings of the output pins , this problem was solved by using an expander . He extends itself BeagleBoard by another 16 pins . On these pins are connected together on the LCD matrix keyboard . The creation of the board are two circuit temperature sensors , but have a different type of communication using I2C and one second using 1 -Wire bus . The board also contains various other bus outputs , for example, UART bus. It also contains an output pin which can be controlled PWM modulation . The remaining pins are versatile GPIO pins which can be programmed to define a function using the Linux operating system . The result is a final board of the package control programs which make it possible to verify the individual peripherals.

Control Unit for Autonomous Vacuum Cleaner
Matějů, Jan ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
This paper is in introduction focused on review of robotic vacuum cleaning and evaluation of available products qualities. However the main focus of this paper is system design of all subsystems, control systems and PCD design of robot electronics. In this paper is also described a method for evaluating approximate distance of robot from the obstacle. There are also described problems of system design of IR proximity sensors. The last part of this work is development of control software for robot and its testing.

Wireless temperature sensor with high temperature warning indicator
Dvořák, Petr ; Petržela, Jiří (referee) ; Hruboš, Zdeněk (advisor)
This thesis deals with a proposal of a wireless temperature-sensitive element at high temperature. It analyses some different variants of the temperature sensors. Furthermore, the thesis describes the Industry Science Medical (ISM) bands, in which it will be possible to communicate with the wireless communication modules. These wireless modules are discussed and described. By the devices „the transmitter and the receiver" it is focused on the communication of the microcontroller Atmel with the wireless modules, with the temperature sensors, microswitches on the control and display unit (LCD).

Control and measurement unit for plasma generators
Paulovics, Petr ; Boušek, Jaroslav (referee) ; Zemánek, Miroslav (advisor)
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.

Control and signalling unit for sport match
Bohutínský, Jaroslav ; Chmelař, Milan (referee) ; Kolouch, Jaromír (advisor)
The aim of this study is a design of a control and signalling unit for sport meetings controlled by a microcontroller. The unit should display the time, the state of the match, eventually another data important for a course of the match. It should be fitted by an audible alarm of the end of the match. A touch control panel with a liquid crystal display serves as input of control data. The unit operates in a countdown mode, it is possible anytime to start or to stop the time by pressing the button. The equipment is mains-operated and backed up by an external battery. In the case of a power failure, it is switched over to the battery. A representation of the time, the state of the match and other data is done by LED displays. The unit allows a connection to PC.
