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.

Trajectory Planning with Laser Proximity Scanner
Přecechtěl, Vít ; Burian, František (referee) ; Žalud, Luděk (advisor)
This thesis deals with a trajectory planning for a mobile robot using measured data obtained from proximity laser scanner, which is mounted on mobile robot. The document begins with brief explanation of the trajectory planning problem in an unknown environment. Thesis continues with description of proximity laser scanner, physical principles and its aplication in robotics. After that hardware and software resources used for implementation and testing algorithms are described. The most important hardware is proximity laser scanner SICK LMS111 and evaluation board STM32F4-Discovery with 32bit microcontroller ARM Cortex-M4F. Software SOPAS Engineering Tool provided by SICK company is used for setting LMS111 scanner. Microcontroller programming has been done in integrated development environment CooCox CoIDE. Last part of thesis describes the algorithms of data segmentation, planning the longest trajectory and planning wall following trajectory of mobile robot.
