Audio digitizer using recording to SD card
Harsa, Jan ; Hubík,, Vladimír (referee) ; Šebesta, Jiří (advisor)
This thesis deals about a digitizer design. The digitizer is part of air-band monitoring receiver. Requirement is digitalization of two audio signals. The device communicates with PC through USB interface and it provides reading and writing to SD card. The STM32F4DISCOVERY development board with processor STM32F407VGT6 was used for design and function testing. This development kit is supplemented with other peripherals on an extern board (input audio circuits and SD slots). The thesis describes briefly theory for each issue which this project deals with. One part is engaged to the hardware design. Then there is a description of the PC software for the device controlling. The main part of the thesis is about the development of the firmware for MCU, which manages AD conversion, formatting of the voice signal, USB communication (HID and Mass Storage class), recording and reading from the SD card and additional peripherals.

[Elko EP] Access Point for Wireless Control System of Electrical Appliances
Vrana, Ondřej ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This work is concerned with development of module for communication with intelligent instalation into houses system. The aim was to familiarize with the products of RF Control of ELKO EP, s.r.o., USB bus and wireless communication components for the 868 MHz band. And afterwards, in cooperation with the ELKO EP company, to design an electrical scheme and printed circuit board motive of this module. For cooperation with the module and for the system components control an aplication was programmed. The application name is RF-AP USB.

Electronic power-supply for high-pressure lamps
Prachař, Petr ; Kubíček, Michal (referee) ; Šotner, Roman (advisor)
This paper describes the principle functions of high pressure sodium and metal halide lamps. Electronic control circuit involves specific feaures (dimming effect). The proposal is implemented with emphasis on high efficiency and high power factor. An important factor in the proposal is also possibility to connect a many types of high-pressure discharge lamps with different electrical properties. The output inverter operates in resonant mode at high frequency and it is controlled by a microprocessor. It is powered by a bridgeless buck power factor correction.

Numeric keyboard
Hladký, Pavel ; Novák, Lukáš (referee) ; Šteffan, Pavel (advisor)
This thesis deals with design of numeric keyboard, which can be connected to personal computer or laptop through USB interface. This numeric keyboard can be also configured using application for operating system Windows. Backlight pattern generator is also part of this application. Theoretic part deals with various types of keyboards, switches and closer description of USB interface. Practical part deals with sole design of circuit that detects keystrokes and sends information about active switches through USB, description of used components, description of microcontroller service routine and description of the application for backlight pattern generating. At the end of this thesis are described results of measurements which were made to choose mechanical switches with shortest debounce time and keyboard response to key press.
