Image Processing in Embedded Systems
Frank, Igor ; Nosko, Svetozár (referee) ; Najman, Pavel (advisor)
This thesis deals with creation of unusual input device based on image processing. More specifically, it's input device where camera captures keys printed on paper. Those keys are then used by user to control multimedia applications. The goal of this thesis was not only creation of such device, but also gaining new knowledge about image processing. The whole work is then devoted to analysis of existing solutions, basic theory, design and device implementation itself.

Embedded Device for Robotic Arm Control
Kyzlink, Jiří ; Goldmann, Tomáš (referee) ; Orság, Filip (advisor)
This diploma thesis deals with a design and implementation of an embedded device (module), used to control a robotic manipulator. The module instructs servomotors of the manipulator to move according to the commands received via USB interface. The module consists of two double-sided printed circuit boards. The first one allows connection to the CAN bus, redundant and thus reliable power supply for servomotors as well as the whole module. The second board, compute oriented one, embeds powerful microcontroller used to communicate with the servomotors and to solve the kinematics tasks. As a part of the thesis a graphical user interface as well as a web-oriented interface were developed. Both interfaces allow full control of the manipulator. All the communicating buses, tools and methods used during the design and implementation phases of the work are described in the thesis. Finally, measurements proved improvement of the motion smoothness and response times in several orders of magnitude in comparison to the previous system.

Embedded system for date collection
Varga, Kamil ; Štohl, Radek (referee) ; Macho, Tomáš (advisor)
This master's thesis is describing problems of embedded systems and their development. Furthermore, the operating system GNU/Linux and it's cross-compiling is described. Hardware problems are analyzed too. Concrete solution is system which is able to boot from the USB disc and it is based on OpenWrt distribution running on Edimax BR-6104KP router. The whole solution is described the way which can lead to any general embedded system.

Microcomputer in Ultramicro Aircraft/Helicopter
Široký, Adam ; Přibyl, Bronislav (referee) ; Zemčík, Pavel (advisor)
This thesis deals with the development of embedded system for ultra light airplanes and helicopters. The aim is to suggest, make and test the system with help of which it would be possible to take notes of a flight data set. The set is formed by GPS coordinates, altitude, speed and leans in both axes. The base of the system is created on microcontroller of the MSP430 family by Texas Instruments. A reader will be offered the used hardware, the system suggestion, its realization, the way of function verification and the possibility of using of the suggested system.

Gateway for Smart Home
Čechmánek, Martin ; Žádník, Martin (referee) ; Novotný, Tomáš (advisor)
In area of Smart-home control, there are requirements for miniaturisation, security and advanced control logic of individual member of system at present. One of the challenges is the way of data collecting from terminal nodes and data processing, including their distribution to the others nodes of Smart-home. The goal of this thesis is to design and to produce Smart-home control node, which will be a gateway between sensoric net and database and will be developed and produced on embedded system with speci c HW boards. Functionality of this gateway should include error states, e.g. should cache sensor messages when the connection between gateway and server interrupts, or take care about time synchronising. The thesis describes theoretical side of gateway design and also practical side of programming and producing SW for the gateway in Smart-home system.

Remote device control over TCP/IP
Skalník, Marek ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
This work describes an application of the ATMEL micro-controller AT91SAM7X512, with ARM architecture, for use with ethernet interface. A part of the work gives attention to the development environment Eclipse used for design and compilation of applications and also to the SAM-BA software by ATMEL utilized for upload of the particular application into the micro-controller memory. Next part describes possible usage of the Real-time operation system (RTOS) in embedded systems and shows a demo application of a webserver with an option to set IP addresses.

Wireless Signal Transmission of DMX512 Interface
Polóni, Pavol ; Jaroš, Jiří (referee) ; Šimek, Václav (advisor)
Master's thesis deals with design and implementation of a system for wireless transmission of DMX signal 512, which is primarily designed for the management of lighting effects. Its electrical specification is based on the EIA485 standard. Text of the work describes the design stage. First is the issue of implied actual protocol DMX 512 or EIA485. Next sign on selecting a suitable architecture for wireless transmission, management and compilation of the block diagrams. Describes the operation of the component selection and circuit implementation of the scheme, which is using the DPS Eagle compiled. In conclusion, this work is to evaluate the results of the proposed system and showing the way to its further development so that it can be realistically implemented in practice.
