Signal Processing for UHF RFID Reader
Novotný, Jan ; Zamazal, Michal (referee) ; Povalač, Aleš (advisor)
The master’s thesis is focused on the UHF RFID reader EXIN-1 signal processing. The first part describes the concept of the EXIN-1 front end, its basic testing and possible communication interfaces for reader control and for receiving and transmitting baseband signals. The second part of this work is aimed to a simple description of EPCglobal Class-1 Generation-2 UHF RFID Protocol, especially to used modulations and codings. In the last part, a block connection between the front end and an ARM Cortex-M4 microcontroller discovery board is designed. The microcontroller is used for generating of all required signals and also for receiving incoming signals and processing them for identification numbers of RFID cards (tags), which are in the reading range of the reader. A decoding algorithm is designed in MATLAB software and implemented to the selected microcontroller. Obtained identification data are displayed on an LCD display and also sent to a PC through a serial communication.

MODAS DataPoint binary and analog inputs tester
Beránek, Jakub ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
Main accomplishment of this master’s thesis is to make a module for verification of the function binary and analog inputs (analog inputs only for current loop between 0-20mA) on data logger MODAS DataPoint. Hardware testing device will be made on development kit STM32F3-Discovery from STMicroelecronics Company. Device generates testing signals for confirmation of the function MODAS DataPoint device. Testing device communicates with MODAS DataPoint device via Ethernet, communication between PC application and hardware of the testing device is realized by USB interface in DFU mode. Solution included PC application, where you can connect to the tester device and tested Modas DP device. Furtheremore, the test starts here and application inform user about during a test, processed measured data and generate output protocols.

Computational Performance Of Arm Cortex M4 Andm7 Microcontroller On Motor Control Application
Otava, Lukáš
The paper is focused on a comparison of three microcontrollers from computational performance point of the view. The comparison is performed on motor control and fault detection algorithm code executed from microcontroller internal FLASH memory. This code contains more complicated mathematical functions. The computational performance is compared according to computational time on STM32F4, STM32F7 and SAM E70 microcontrollers. Another aspects (like core clock frequency, FLASH configuration, cache configuration, etc.) of microcontroller settings are taken into account in experimental results.
