USB thermometer
Holub, Jiří ; Kubánek, David (referee) ; Lattenberg, Ivo (advisor)
This bachelor thesis deals with a problem of electrical measurement of temperature. It describes a various types of temperature sensors and processing data obtained from these. It describes in short the USB interface and its parameters. It also contains a design of hardware and software solution of thermometer using temperature sensor SMT 160, managed by microcontroller ATmega16 and communicating with PC via USB interface. Designed thermometer also offers possibility to save measured data to built-in memory and later load them from there. Measured data will be also displayed on LCD. Last part of these thesis is design of application for PC, which will serve for displaying measured data and adjustment of thermometer.

Remote Control for Positioning Device
Ťapucha, Andrej ; Hanák, Pavel (referee) ; Schimmel, Jiří (advisor)
This thesis describes the design of 2D adjustable, equipment for acoustic measurements in laboratories. It uses models and linear axes MAXS1BR PAS41BR ILS1R573PB1A0 with engines from Schneider Electric. Engines include power electronics and their Steering operation takes place via communication protocol RS - 485th It was therefore suggested communication hardware which, from a personal computer orders transferring the corresponding protocol. Operation takes place in two modes, the first setting of the measuring microphone is fixed in position and the second is a shift between two points specified speed. The device of prevodníkom drafted by the USB processor to ATMEGA 162 and then the log RS - 485th Part of the work is and design of mechanical parts, serving to link the two axes and subsequent attachment of the stand. Other mechanical devise was part of a bracket for fixing the measurement microphone and would meet the requirements of universality.

Induction Heating Control Unit
Válik, Martin ; Čožík, Ondřej (referee) ; Macháň, Ladislav (advisor)
The text is focused on development induction heating coltroller. The motivation to create such a device was to correct deficiencies and add the necessary functionality for a device of this type. This was achieved mainly by adding the graphic display and USB interface. Graphic TFT display with buttons and a rotary encoder creates user interface. Part of the control unit is also circuit evaluateing temperature from three thermocouples. The paper dealt with the optimal solution for power supply, communication between control unit and power part, way of controlling graphical TFT display and selection of other components. The core is of course, suitable microcontroller, which manage all parts of the device.

USB Key
Slimařík, František ; Růžička, Richard (referee) ; Strnadel, Josef (advisor)
These days USB interface belongs to the most used interfaces for communication between computer and external devices. It must satisfy strict requirements to be provided its multiplatformity. In the process this interface found its use even in microcontrollers. This thesis is focused on design, compilation and programming of hardware USB key of HID standard with usage of microcontroller MC68HC908JB8.

Digital Oscilloscope on FITkit Platform
Veškrna, Ondřej ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
This thesis deals with the design of a device that enables to monitor the behavior of the measured signal on the computer screen, using the principle of the digital oscilloscope. The control element of the device is the field programmable gate array (FPGA) on FITkit platform. The FPGA configuration controls the input signal sampling and sends the received samples through the USB interface to the PC. The graphical application implemented in the computer tries to restore the signal and then displays it on the screen.

Temperature Monitoring
Kotačka, Aleš ; Winter, Jan (referee) ; Kubek, Ján (advisor)
This master's thesis deals use FITkit for longtime temperature monitoring without necessity connection on PC. Describe possibilities connection different heat-sensitive elements to FITkit inclusive physical realization. Further this thesis deals with measuring of temperature, displaying temperature and saving to memory, blocks-partitioning of memory. Is defined communication protocol between FITkit and PC for bulk downloading of data. So are solving problems with saving measure data to text files and next processing in table processors.

Peristaltic pump control via USB interface
Balogh, Jaroslav ; Chmelař, Milan (referee) ; Čech, Petr (advisor)
The purpose of this bachelor’s thesis is to practical realization of connection between peristaltic pump Rainin Dynamax RP-1 and PC, using USB interface. Integrated circuit device FT232R has been used in USB-RS422 converter, due to modified RS422 interface, which the pump RP-1 uses. There was also developed software for pump’s remote controll. RP-1’s functions can be driven from remote side or eventually automatized with this software. This work is based on semestral thesis and in future can be used in another aplications with RS422 or with RP-1 pump. Department of Biomedical Engineering, attached to FEEC, Brno University of Technology, will use this remote controll in analysis of DNA.

Design of the sinusoidal high voltage source
Uherek, Jaromír ; Boušek, Jaroslav (referee) ; Frk, Martin (advisor)
Object of the master´s thesis is design of a high voltage power supply for testing insulation materials with output voltage 50 V - 2 kV at fixed frequency 50 Hz. The power supply is controlled by personal computer and measured data are sent back to the personal computer. The Universal Serial Bus (USB) is used for communication between the PC and the device.

Communication Environment for Spectral Analyzer Control
Smělík, Martin ; Šebesta, Jiří (referee) ; Dřínovský, Jiří (advisor)
The aim of this master‘s thesis was design a new communication interface for spectral analyzer Seaward EMC Spectrum Receiver, which instead of the RS 232 interface is connected to a computer via the USB interface. This thesis contains both hardware and software solution based on the analysis and comprehensive understanding of communication between the spectrum analyzer and the computer. Further it contains the whole realization of communication interface and an example of measurement of the EMC problems too. Last part of this thesis was a realization of the automatic measurement via the development environment MATLAB and Agilent VEE, which was used for measurement of noise background.
