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.

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.

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.
