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.

Accelerometer-based monitoring of steering wheel angle
Navrátil, Tadeáš ; Jirgl, Miroslav (referee) ; Mihálik, Ondrej (advisor)
This thesis deals with the design of a device which will be used for measuring the steering wheel angle. Main goal was to design basic concept of device which is using data gathered from three accelerometers in the reconstruction algorithm to get steering wheel angle. Discussion of various reconstruction algorithms (with regards to simulated output noise levels from acceleromater) and final Implementation of reconstruction algorithm (in MATLAB simulink enviroment) is also part of this thesis. Furthermore, thesis deals with the selection of suitable components. Mainly selection of accelerometers, microcontroller and the selection of a suitable communication bus for mutual communication between them. Thesis also deals with design improvements of algorithm and realization of the whole device. In the end, we compare results of measuring device and inner senzor of steering wheel.

Communication assembly for optical cableless linking
Kapuš, Martin ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
This Graduate Thesis is about communication module for optical wireless network. This device read data from RS232 port and two analog inputs and sends it through internet to a remote Computer. Furthermore allows voice communication between local user on module and user on remote computer. Device allows communication with standard headphones and microphone, or with Bluetooth handsfree. Basic part is microprocessor MCF5223 and Bluetooth Ezurio BISM II module. Control program has been written in C language. Printed circuit is created by EAGLE program. This device is managed via web interface and settings have been stored into EEPROM memory. Work contains description of separately parts and blocks, source code of program, description of source code and printed circuit designs.

Controll Module for Circuits with ADF4360 and Selected DDS
Lambor, Jiří ; Vágner, Petr (referee) ; Urbanec, Tomáš (advisor)
This bachelor’s thesis is focused on issues of communication between microprocessor unit and frequency synthesizer circuits - direct digital synthesis circuit (DDS), voltage control oscillator with phase lock loop (ADF). The basic theoretical function of DDS, ADF and SPI interface is described in the introduction. The solution and drafts of modules hardware are shown in next chapter. Last chapter describes programming of DDS and ADF circuits with examples of this code in C language. Schemes and board layouts of modules are attached in appendix.

Harness tester
Smola, Tomáš ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
This thesis deals with issue and construction of wire harness tester. In the first place, is this thesis focused on market exploration and comparison of comercial testers with concrete requirements for small batch production. I will try to find a suitable product in worldwide market, which would be convenient for company producing construction machinery. For testing switchboard harness we need to test interconnections between connectors, resistors, relays, diodes, transils and switches in the dashboard. If I can not find some product, I will try to design some new tester. My priorities will be testing all components in harness, maximum flexibility of tester for the future trends in contruction of rollers and user friendly control.
