I2C Bus to RS232 Bus Convertor
Votava, Martin ; Marvan, Aleš (referee) ; Orság, Filip (advisor)
The main goal of this Bachelor's thesis is to create I2C bus to RS232 bus convertor. Using I2C bus the convertor drives 8bit I/O expander. In theoretical part buses I2C and RS232 are described along with PCF8574. There is also mentioned selection appropriate microcontroler and design of comunication protocol. Practical part is dedicated to creating control program for microcontroler, appropriate comunication protocol processing and convertor testing. There are also described some auxiliary products and program testing.

Algorithms for decoding the Reed-Solomon error control code
Tieftrunk, Tomáš ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
Thesis discuss about effort to ensure from error, which may occur during transmission over noisy channel. There's used Reed Solomon code. It's block, cyclic and systematic code, which is symbol orientated. Computational process of decoding is mathematically time-consuming. In thesis is closely described Berlekamp-Masey algorithm, used in decoding to evaluate error polynomial. Process is illustrated in application in Matlab. Practical realization uses Reed Solomon code in communication over RS232. Communication is established between computer and microcomputer.

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.

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.

The remote-control workplace of sensor technology
Knopp, Daniel ; Vaško, Cyril (referee) ; Adámek, Martin (advisor)
This thesis is focused on a specific virtual laboratory support, which is designed and created as a device capable of data transferring to display and/or computational unit via serial port. Both the device and common PC are generally a corner stone of each virtual laboratory, which can be also accessed via internet. Technique, significant factors with impact of analog disturbances on digital communication and realization of standalone virtual laboratory are described in detail.

Graphics indicator
Dvořák, Roman ; Šír, Michal (referee) ; Bradáč, Zdeněk (advisor)
This thesis is consisting of three parts. In first part was conducted market research and then start preparation concept of project Graphic indicator units using in industrial environment. Creating a basis for continued in making electronic schemes and board. Then the board was made in external specialization company. Then all components were installed. After testing all of function the device was ready for implementation firmware. Firmware was consist of few parts – communication with RS232 protocol, RS485, web interface and last parts is communication with touch display.

HC08 Microcontroller Development Kit
Hájek, Ondřej ; Sekora, Jiří (referee) ; Čížek, Martin (advisor)
Presented bachelor degree programme is aimed on design and implementation of a development board for Freescale HC908QB8 microcontroller from HC08 family. The board will allow the user to test a variety of typical microcontroller applications including temperature measurement, intelligent LCD interfacing and I2C bus communication. The development board can be programmed using universal DBG08 serial programmer. Care was taken to minimize the probability of an accidental misconnection causing potential damage to the circuit, which makes the device suitable for educational purposes.

Multifunction data acquisition, measurement and control device
Trávníček, Ivo ; Vlachý, David (referee) ; Grepl, Robert (advisor)
The thesis deals with and tests the Multifunction data acquisition, measurement and control device. The unit is based on the microcontroller ATmega, which was programmed in the language C. The unit contains functions for the measurement of physical quantify, filtering record, regulation of the dynamic systems and communication with PC. Configuration of the unit is real-time in special software created in the language Matlab or by a terminal. The purpose of the unit is controlling a DC motor by the PID regulator, long-term measurement of temperature or measurement of acceleration by an accelerometer.
