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.

FLATcon system – CCD detection of media meters with RF communication
Lancz, Michal ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
Bachelor’s thesis deals with designing the concept of battery powered miniature microcontroller system based on CCD detection of media meters. The FLATcon design concept contains the necessary inputs and outputs for communication with microcontroller and with peripheral devices. The aim of the thesis is to detect the state of a media meter equipped with an analogue dial, to save the scanned image along with the scanning time and forwarding through the RF module. The bachelor thesis describes FLATcon system design, soldering and supplying the system and testing peripheral devices.

Modbus TCP interface
Krotký, Pavel ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
Main puropose of this thesis is to design and develop Ethernet to serial interface converter. Ethernet and serial line protocols are briefly described. Appropriate microprocessor and hardware for realisation of each physical layars were choosen. Convertor uses Texas Instrument's TI-RTOS operating system. Convertor's purpose is to pass on communication between physical layers and also fulfill webserver role with configuration possibilities.

System for communication between model car and PC
Petrov, David ; Beran, Jan (referee) ; Macho, Tomáš (advisor)
Bachelor thesis addresses communication between PC and carriage. It includes analysis of possible ways to transfer commands from PC to mobile robot. The resulting solutions are selected hybrid wireless modules Aurel RX BC-NBK-433 and TX-SAW433 / s working in the band 433 - 868 MHz. For the processing of transmitted data is used microcontroller PIC16F627A.

Programmable timer configurable via USB
Dresler, Jan ; Číž, Radim (referee) ; Lattenberg, Ivo (advisor)
This thesis describes the design of printed circuit boards and programming AVR microcontroller, that communicates with the digital thermometer Dallas, also with photoresist circuit and RTC. Using sensors and relay allows switching of different devices. The switch allows direct configuration with computer via USB using the auxiliary circuit UART.

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.

Design of electronics and control for touch screen devices tester
Hrůzek, Jan ; Bednařík, Josef (referee) ; Krejsa, Jiří (advisor)
This thesis deals with a complex design of control electronics for device dedicated to testing touch panels and subsequent implementation of basic communication interface between microcontroller and service PC. There is a detailed analysis of selection procedure of suitable sensors for testing device and of suitable components for control and power circuits as well. The connection and interconnection of all necessary components is solved, including the temporary replacement of the main microcontroller with the Nucleo development board. The UART protocol is used as a tool for communication with the operating PC and Python is used on the operating PC side. It also outlines the extension of the content of this thesis when extending the system with a second device.

Arduino based serial bus decoder
Giertl, Juraj ; Lattenberg, Ivo (referee) ; Krajsa, Ondřej (advisor)
This project deals with possibilities of capturing and decoding data from different serial buses. Then describe ways of automatic recognition of the buses. The project include hardware and software development of device used for capturing data from different serial buses such as SPI, UART and I2C. Characteristics of these busses are described in detail. Device is design as shield to support Arduino boards. The Shield includes four fully isolated inputs and five non isolated imputs for capturing data, Ethernet interface, SD card and two display interfaces witch supports up to ten displays.
