Secure PC Connection
Winter, Jan ; Škarvada, Jaroslav (referee) ; Kubek, Ján (advisor)
Aim of this master's thesis is the creation of serial communication interface for FITkit. This serial interface is a full duplex industrial bus based on 20mA loop circuit and it should allow connection of two FITkits by RS-485. Aim of this paper is to design simple software allowing communication of two FITkits and to secure this communication on RS-485 link against interference or transfer errors.

Serial communication
Novotný, Bohumil ; Šilhavý, Pavel (referee) ; Martinásek, Zdeněk (advisor)
Bachelor work is focused on the issue of a serial communication interface RS-232,USB, I2C and SPI, and also discusses the use of the laboratory module for experimental purposes. Laboratory module is designed with respect to the functional elements that will resist daily use of students. This work is detailed principles of serial communication in relation to each interface. The second part is devoted to method the module structure, functions of its individual components and functional solution output connectable to an oscilloscope and other measuring devices.

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.

Wireless interface for digitally-controlled applications
Valouch, Martin ; Rumánek,, Jaroslav (referee) ; Brančík, Lubomír (advisor)
The thesis aim is in practical realization of wireless interface, which is created by infrared relay in motorcycle Simson. Infrared relay is used for speed measuring. This work describes the realization of digital controlling by microcontrollers. Digital controlling can easily improve and upgrade functions for better driving comfort. It’s possible by getting information about condition of selected motorcycle parts. This information can be engine temperature, battery charge, total distance and etc.

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.

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.

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.

Intelligent monitoring device
Nosek, Zdeněk ; Šteffan, Pavel (referee) ; Kadlec, Jaroslav (advisor)
This master thesis discusses design and realization of a security device for vehicles. This device can determine its actual location, discover unauthorized trespass and send information about this to a distant master system too. This distant master system can show the exact position of the security device on a map. The hardware and software for this security device and the software for the master system are described in this paper.

Microprocessor Controlled Power Measurement System for Frequencies below 10GHz
Klíma, Martin ; Lukeš, Zbyněk (referee) ; Urbanec, Tomáš (advisor)
The aim of this work is to design a microprocessor controlled power measurement system which is based on the logarithmic detector AD8317, then to create a printed circuit board and to test its functioning. The logarithmic detector AD8317 is acceptable for measurement of high frequency signal’s power of the level between approx. –55 dBm and – 3 dBm in the frequency bandwidth of 1 MHz to 10 GHz. Its output provides DC voltage which is corresponding to the decibel-scaled level of the input signal. This is suitable for A/D conversion and digital processing by the microprocessor. The result of the work is a complete measurement system.

Periphery tester with Single chips AVR ATMEL acquisition
KROUPA, František
The objective of this Bachelor?s thesis was to design a tester of I2C, SPI and 1WIRE interfaces. In the theoretical part of the thesis, these interfaces as well as protocols are described. In the practical part, a design of the device and description of its functions are presented. The device is composed of two main components, a "master" (PC visualization of tester controlling) and "slave" (microcontroller ATmega-8 and FTDI 232). Function of the device was verified in practice.
