System for Programming Minerva Platform
Dohnal, Michal ; Strnadel, Josef (referee) ; Bidlo, Michal (advisor)
Theoretical part of this thesis studies several concepts and interfaces being used for programming microcontrollers (MCUs) and reconfiguration of field programmable gate arrays (FPGAs) with closer look at those, which are available for MCU Kinetis K60 and FPGA Spartan-6 in circuitry given by the architecture of educational kit Minerva. This knowledge is employed in practical section which describes deployment of the supporting firmware belonging to group of firmwares so-called bootloaders. Finally the application QDevKit3 is introduced, that is based on this firmware, representing effective and fast way for easy programming of FLASH memory on Kinetis MCU using USB interface.

Measuring of System Load in Embedded Linux
Skopal, Jakub ; Korček, Pavol (referee) ; Viktorin, Jan (advisor)
The bachelor thesis describes the quantities which characterize the load of the embedded systems based on the Linux kernel. The library was designed and implemented to observe the load of the system in order to facilitate and unify the observation of individual quantities and their reciprocal coherence. Due to the lack of external dependencies of the library the memory requirements are low. To demonstrate the use of the implemented library, a program was designed which depicts the graphs of measured quantities in real time on a remote computer.

Implementation of RTOS into STM32 microcontrollers with ARM Cortex-M4F core
Gothard, Adolf ; Valach, Soběslav (referee) ; Macho, Tomáš (advisor)
This masters's thesis deals with choice and implementation of two free real-time operating systems into powerful 32-bit microcontroller with ARM Cortex-M4F core. First, there is shortly described the ARM architecture in general, its programmer's model, instruction set and Cortex-M4F core in brief. Next is description of the architecture of used microcontroller STM32F407VGT6 from ST Microelectronics, description of its integrated memories and their organization and functions of its integrated A/D and D/A converters. Next part of this thesis deals with searching real-time operating systems with ARM Cortex-M4F core support and then choose two of these systems for the implementation. The chosen operating systems are more closely described in two following chapters. Next chapter analyses possible implementations of the digital PSD controller and more complex system of such controllers using real-time operating system. Following chapter describes implementation of chosen operating systems and designed controllers. Last chapter deals with evaluation of features and qualities of the chosen real-time operating systems for implementation of embedded control system.

Motion detection based on an accelerometer measurement
Štancl, František ; Šimek, Milan (referee) ; Pál, Tamás (advisor)
This thesis is devoted to detect motion and it is focused on energy consumption. The introduction involves possible ways for acceleration measuring and discusses The MEMS technology in accelerometers. It also describes components used in a low-power module and some suggestions leading to resolution of this issue. This thesis includes the module design as well, PCB design and software equipment. Finally, it evaluates the results and the solution accuracy.

Analysis of State Automatas for Embedded Applications
Maťas, Marek ; Blaha, Petr (referee) ; Václavek, Pavel (advisor)
This master’s thesis deals with analysis of state machines for embedded applications. The issue of finite-state machine is described theoretically. The document also contains a proposal for funding for modeling finite state machines in Matlab/Simulink. It is designed data representation of finite automaton. Over this data representation algorithm of minimization is applied. Finally, the algorithm is implemented to generate code in C language.

Monitoring device for level crossings
Navrátil, Tomáš ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
Bachelor‘s thesis deals with a design of a safety appliance. The device will be used particularly at grade crossing. The record device allows monitoring of digital signals with the basic board and with microprocessor ATMEGA 128. Signals are patterned each second. The device is equipped with a USB interface, RS 485, ethernet and SD card. The capacity of SD card is designed for 40 days. The basic development board Ethernut, to which additional circuits were connected, was used for testing basic functions. Records are saved on a removable memory SD card in FAT 16 format. Old records are overwritten when the card is full. The project includes a description of communication with USB interface, a technical design of USB interface with photography of the hardware. Bachelor‘s thesis characterizes features of the SD card, communication and a description of the file system FAT 16. I also introduce a design of connecting SD card to the microprocessor within the SPI interface. All software was written in programming language C. There are described main functions of the code and their parameters.
