Firmware for the Robotic Vehicle
Otava, Lukáš ; Sojka,, Michal (referee) ; Kučera, Pavel (advisor)
This thesis is focused on a firmware for robotic vehicle based on the ARM Cortex-M3 architecture that is running a real-time operating system (RTOS). Theoretical part describes available solutions of embedded RTOS and concrete HW implementation of the robotic vehicle. There is also comparison of the three selected RTOS with their measurements. Result of this thesis is base firmware compounded by a program modules that controls HW parts. There is also a sample PC and firmware application that extends base firmware. This sample application is able to communicate with robotic vehicle, control wheel motion and measure process data.

LED light with adjustable spectral radiation for breeding and growing
Satora, Ondřej ; Hrach, Petr (referee) ; Klozar, Lukáš (advisor)
The aim of my master’s thesis is the design of the LED lighting system for breeding and growing purposes as replacement for the classical high-pressure sodium lamps and other sources of light used today. The whole system can be controlled locally by buttons or remotely by web server using Ethernet interface. LEDs are powered by five-channel step-down converter with current feedback. Converters are controlled by pulse width modulation generated by microcontroller.

Utilization of ARM GCC toolchain
Ledvina, Jan ; Matěj, Zdeněk (referee) ; Fedra, Zbyněk (advisor)
The subject of this thesis is to study the existing development toolchain for the microprocessor LPC23xx in course MPOA. Main goal is to explore the feasibility of new development toolchain, based on the GCC. The outcomes of this thesis are demo applications with the microprocessor LPC2378 and the GCC. Parts of the outputs are also tutorials for the students, how to implement these demo applications. The demos include basic applications, RTOS and Ethernet

Universal Control System for Quadrocopter
Gábrlík, Petr ; Kříž, Vlastimil (referee) ; Žalud, Luděk (advisor)
The Thesis objective is the design and implementation of the universal control system for a flying robot, quadrotor concept. The first part deals with ways of solving program for microcontrollers. The special attention is given to the FreeRTOS real-time operating system, which is designed for microcontrollers. The second part of the Thesis is focused on the description of the chosen microcontroller LM3S8962 and the hardware solution. One chapter is devoted to the integration of the robot to the Cassandra-WPF robotic control system. The third part deals with the identification of the new robot construction and the mathematical model creation. Using the model controllers for stabilization pitch and roll are designed and their functionality is verified on a physical model. The last part of the Thesis is focused on the FreeRTOS implementation and the control application creation.

TCP/IP and Modbus modules for OS FreeRTOS
Šťastný, Ladislav ; Macho, Tomáš (referee) ; Valach, Soběslav (advisor)
The aim of this work is to get familiar with operating system FreeRTOS and its usage in device design. It also explains usage of SW module LwIP (TCP/IP stack) and Free-MODBUS. Consequently is designed example device, simple operational panel. The panel communicates through ethernet interface using Modbus TCP protocol with connected PLCs on separate network. Its meet function of webserver, HID and also source of real time.

Signal processing algorithms on AVR32 platform
Záplata, Filip ; Fajmon, Petr (referee) ; Fedra, Zbyněk (advisor)
Master‘s thesis reviews the characteristics of the AVR32 architecture, AVR32UC microarchitecture, and especially AT32UC3A0512 microcontroller. This microcontroller is mounted on the board EVK1100, which is used for debugging applications. The entire analysis is focused on the ability to process audio signals on this board. For the board is created AD/DA interface and its control library. Follows necessary description of used DSP-lib library. The last part is a description of the theory and implementation of two sound effects and implementation of operating system FreeRTOS.

IPv6 for Wireless Sensor Networks
Polak, Martin ; Komosný, Dan (referee) ; Červenka, Vladimír (advisor)
This thesis deals with the issues 6LoWPAN protokolu and implementation of IPv6 on the specied platform. Introduction thesis deals with the explanation of wireless sensor networks. Next it was descibed 6LoWPAN protocol, which maps IPv6 on standard IEEE 802.15.4. The thesis further concentrates to exploration of possible operation systems, that are designed for sensor networks and then followed by comparison of their characteristics and advantages. The fth chapter is focused on he implementation of the operating system to the sensor node Iris, introduction Iris and with the structure of the operating system Contiki OS. At the end of thesis is description of the implementation of this system in the sensor node Iris.

Atmel AVR32 UC processor demo application
Zajíc, Jakub ; Hanák, Pavel (referee) ; Fedra, Zbyněk (advisor)
The diploma thesis provides a brief overview of the architecture Atmel AVR32 UC. Project deals mainly AVR32 processor UC3A and processor AVR32 UC microarchitecture. From The Microarchitecture AVR32 UC3A was derived processor AT32UC3A0512. This processor is used for the development board EVK1100. Options of this plate are also investigated. Basic information about programming and AVR32 Studio development environment for these processors are given. After the acquisition of control of the IDE and study the attached sample application a simple program was created. This program was integrated as a task operating system FreeRTOS along with several another tasks.

Module of electronic security central with Ethernet communicator
Strašil, Ivo ; Pust, Radim (referee) ; Burda, Karel (advisor)
This diploma thesis deals with a design of a burglar alarm control panel, equipped with an Ethernet interface. The thesis contains a discusson of present solutions of control panels and of present usage of Ethernet communication. An idea of sensors, directly connected to LAN, was discarded on basis of a component price survey. Finally, a new concept of the panel has been chosen. This concept allows a free definition of internal logic using a C-like scripting and provides a possibility to create a network of these panels in a LAN network, using a software-only supervising main control panel. A new control panel following this concept was designed and succesfully tested.
