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.

I/O Card Controlled by SMS
Bachtík, Martin ; Pavelka, Ondřej (referee) ; Orság, Filip (advisor)
The aim of this bachelor's thesis is design and implementation of a universal device with input-output character. The device detects incitations on few inputs and sets few outputs. The user controls the device via SMS or short multiple dialling. The device interacts with the user via LED diodes, SMS or hort multiple dialing.
