System for Serial Communication Monitoring
Perný, Jan ; Kováč, Michal (referee) ; Kolouch, Jaromír (advisor)
There is a need for a serial communication testing tool when software or hardware developers have to solve serial communication problems. This tool must accurately catch and record the whole communication. Some type of timestamps in the record is necessary for future analysis. This diploma thesis deals with programming a serial communication monitoring equipment software with the possibility of the insertion of timestamps. Possible timestamps types and inserting methods are also discussed. The programmed monitoring software for the FOX Board hardware platform is able to catch and record the serial communication at RS232 ports and add timestamps to the record in accordance to three independent rules. The record is saved to a standard USB flash drive.

Embedded System for Orienteers Race Organization Support
Kavan, Tomáš ; Přibyl, Bronislav (referee) ; Beran, Vítězslav (advisor)
This thesis deals with the design and production of prototype terminal for supporting organization within orienteering races. The aim of this work is to integrate all important computer facilities, currently used in the practice of orienteering races or training, into a portable compact embedded system in the size of a common terminal for accepting credit cards. The secondary objective of this thesis is creation of cross-platform Open Source library for communication with SPORTIdent control units.

Design and realization of serial communication monitor
Šnajder, Jan ; Králík, Jan (referee) ; Krejsa, Jiří (advisor)
Aim of this thesis is design and realization of serial communication monitor. The thesis describes creation of hardware device responsible for collecting data from analyzed communications and for distribution of these data by USB bus. Thesis also explains connection between serial monitor and software Wireshark by extcap interface. Visualization of data in readable format is done by decoding script, which is tested by selected protocol. The last part of the study is focused on evaluation of data permeability of hardware device according to data line fullness.

Tactile Feedback Stimulation
Lang, Matěj ; Harabiš, Vratislav (referee) ; Kopečný, Lukáš (advisor)
This bachelor's thesis is focused on building and testing a tactile interface. As a first step, it describes various methods of creating a tactile stimulus and mentions basic physical principles used. The direct electrical stimulation was chosen as suitable candidate for replication. For this there was created high voltage DC voltage source controlled by Arduino Nano. Also a PCB accommodating series of electrodes connected to control the flow of current. The system is controlled by STM32F4-Discovery. In thesis is described design of PCBs and all created software. The board has been tested and improvements were proposed.

Synchronization of Graphic Application Running on Two FITkits Simultaneously
Kaplan, Tomáš ; Tobola, Jiří (referee) ; Žádník, Martin (advisor)
This bachelor thesis describes development application on platform FITkit. Development on mentioned platform amounts making configuration for programmable gate field (FPGA) by company Xilinx and program making for micro-controller by company Texas Instruments. Application have as one's task demonstrate synchronization of graphic application running on two FITkits simultaneously. Inter-device communication proceeds over serial line.

Communication Adaptor for Data Acquisition System Hardware and Software Design
Kašpar, Petr ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
The aim of this bachelor thesis is to create adaptor with microcontroller for data acgusition system. Function of the device is to receive serial asynchronous string of ASCII characters which was send from ultrasonic thickness gauge. Baud rate of transmittion is 2400Bd. Transmittion is realized according to RS-232 standard. Part of the string contains numeric information about value which was measured by thickness gauge. This numeric information is in microcontroller multiplied with corrective constant and decimal point in result is placed to right position. Corrective constant is stored in EEPROM memory. After that adaptor transsmits data to superior system in format of serial asynchronous string of ASCII with baud rate 9600Bd. Thesis describes service code for microcontroller in Assembler language and hardware construction of device.

Synchronization of the time using the GPS
Švábeník, Petr ; Šmíd, Petr (referee) ; Vyskočil, Pavel (advisor)
This thesis discusses about using the worldwide satellite system GPS for time and frequency synchronization. This thesis presents study about basic principles of the GPS system, its segments and ways of using this system. Some GPS receivers suitable for receiving the time marks (pulses) used for time synchronization are described. Thesis contents designing of the circuit that will receive time marks and it will digitalize and record external signal and send it with precision time information to PC for displaying and post processing. Thesis also discusses about both hardware and software development of the synchronization module and software used in PC.
