Graphical LCD display
Kulka, Branislav ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
Bachelor's thesis "Graphical LCD Display" is focused on designing graphical diplaying unit for displaying industrial data, which is equipped with RS232/RS485 interface and digital inputs and outputs. Device is equipped with I51 series microcontroller. In this work MODBUS protocol is discussed and implemented. Data can be dispayed on circle scale or in form of bargraph indicators.

Precise function generator
Snopek, Petr ; Horský, Pavel (referee) ; Kolka, Zdeněk (advisor)
The aim of the project is to design a concept of function generator with digital synthesis. The device will be controlled using microprocessor which allows synthesizing basic functions (sin, square, raw) as well as arbitrary functions stored in memory. User friendly graphical interface will be controlled by keyboard and rotary switch (IRC). The work emphasizes correct selection of DDS clock source, circuit elements and proper application of signal filtration method with attention to low distortion and low output phase noise.

Additional LCD Display for Laboratory Kit with a Programmable Device
Pajskr, Jaroslav ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
The main part of the digital application is its user interface. Users can check the status of the programme or change its state. There are many ways to obtain a suitable interface. During the design stage the simplest interface is chosen that provides the necessary functions. In most cases the interface contains a display. This diploma thesis deals with the design of an extension board to plug in a display to a programmable device, a control algorithm for the display and the design of a simple display interface. There are two ways to design software. The first of them is achieved by the processor PicoBlaze, which contains all the required functions. The second solution is by the state machine written in VHDL language. Both solutions can be used in the same way, but the latter solution is quicker and requires less hardware resources.

Electronic Compass
Špaňhel, Petr ; Slaný, Karel (referee) ; Šimek, Václav (advisor)
This bachelor's thesis deals with a design and construction of equipment that should offer an easy approach to measurement of temperature, air pressure and angular orientation to the Earth surface. Subsequently, this set of infromation will be shown in a concise way on a graphic LCD display. The introductory chapter provides a general outline to the hardware conception, which primarily involves reading of data from sensors and their graphical visualization. Details on control firmware aspects are included in the following two chpaters. Fourth chapter is aimed at device operation and its user interface. Finally, evaluation of the results and conclusion is provided.

Radiocommunication Monitor for ISM Band at 868 MHz
Frecer, Petr ; Zamazal, Michal (referee) ; Povalač, Aleš (advisor)
This thesis deals with the design and the realization of the radiocommunication monitor for the 868 MHz band. In the thesis, a description of licence-free radio bands complying ITU recommendations and ETSI standards is given. A special attention is paid to the 863 MHz - 870 MHz band. The transceiver CC1020 that forms the base for the monitor is described in detail. The circuit design, the monitor assembly and the firmware creation are presented step by step. The radiocommunication monitor is portable and battery powered. The monitor is able to display RF signals in the 868 MHz band, to indicate the frequency error of the transmitter and to receive FSK modulated signal. Demodulated data can be transferred to the personal computer via the USB.
