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.

USB Keylogger
Lojda, Jakub ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
This bachelor's thesis deals with the design and practical implementation of USB keylogger. The theoretical part is devoted to the USB bus and the description of SD cards. It also describes the selected MCU Vinculum VNC2 and available drivers. The next part analyzes the design and implementation of such device, including the final throughput measurement and identification of the weakest points of the proposed solution. Next part mentions the making of PCB. The thesis includes a CD with full source code, schematic and PCB layout in Eagle, part list and photographs of the finished keylogger.
