Rotational Display
Konečný, Ondřej ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This thesis describes the process of hardware and software development of a rotational display, that uses accelerometer for acquisition of placement data. It explains the principle of operation of the rotational display and of the components that were used. There are discussed various ways of accelerometer usage for these purposes and there is also explained the solution of the problem of timing for the purposes of displaying. In the end the thesis summarizes the results of the development process and outlines possible future development.

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.

Graphics Library for Touchscreen LCD
Klubal, Ondřej ; Šimek, Václav (referee) ; Bartoš, Pavel (advisor)
This work deals with description of graphic library for a touch screen educational kit with a microcontroller from Freescale. Part of this library is a driver that accelerates gradient rendering and supports reading from video RAM. The library allows inserting images with transparency and their upscaling. Multiple fonts are also supported. Fonts can be upscaled and their weight can be set.

DMA Support for HCS08 Microcontrollers Family
Novosád, Adrián ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
Embedded systems are dedicated to perform specific tasks, so design engineers can optimize them to reduce the size and cost of the product and increase the reliability and performance. However, result of these optimizations is that some architectures may lack commonly used technologies such as direct memory access (DMA). We may encounter with this situation in family of microcontrollers HCS08. The main theme of this work is to describe a design of DMA controller that can be added into the family of microcontrollers HCS08.

Miniaturization and Range Extension of W-DMX v1.0 Module
Rojček, Martin ; Jaroš, Jiří (referee) ; Šimek, Václav (advisor)
The aim of this master thesis is to design a wireless system which would be primarily used for a control of stage lighting. Our idea is to establish wireless links, that will carry DMX512 protocol, between individual lighting devices based on wireless transceiver nRF2401A. The foundation of our project comes from a previous design, which was not completely suitable for a practical use because of its rather large proportions and a short RF range. The project resolves the issue of relatively short range coverage through the deployment of RF amplifier RF5722. In the same tme, it also takes into account other technical aspects such as the use of antenas with a higher gain, front-end circuits or increased transmission reliability through frequency hopping scheme. Proper attention is also given to a minimalization of the module dimensions by using SMD components and layout adjustements, so it would be possible to place the whole board inside XLR connector. Set of printed circuit boards with the specified characteristics, which is the expected outcome of our project, were designed with Eagle PCB design environment.

Design of ZigBee device - Analog inputs in range 0 - 10 V
Vepřek, Jan ; Kacz, Peter (referee) ; Štohl, Radek (advisor)
This bachelor thesis deals with design and realization device with analog inputs for ZigBee module. The first part of thesis contains analyse of possible solutions design of device and selecting the best choice. In the second part is function and connection of real circuits which I have used in device. In the third part is introduced function of software and description of functions. The communication between microcontroller and circuits through the use of programmed function is described. The last part is attended to user manual. There are descriptions controls of device and radio communication between two devices.

IEEE802.15.4 and ZigBee technologies, examples of applications
Skládaný, Vojtěch ; Frýza, Tomáš (referee) ; Kováč, Michal (advisor)
The main goals of diploma thesis are application and realization of tool for projection and installation wireless networks according to IEEE802.15.4. The thesis is specialized in construction of transmitter and receiver device in term of mobility and visualization of data measured in terrain. Than the software support for measuring and control appropriate periphery are summarised and described. The system is defined in C programming language and uses OpenMAC library. Last part of thesis is focus on practical measurement and testing tool for projection and installation wireless network.
