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.

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.

Hardware Indicator of Notifications for Smartphones with Android
Bártl, Roman ; Zemčík, Pavel (referee) ; Herout, Adam (advisor)
This thesis deals with design and development of a notification device depicting all kinds of notifications from smartphones. The core of this device is an Arduino board. This thesis also includes an implementation of Android application which handles these notifications and sends them to the device via Bluetooth Low Energy. There is an emphasis on simplicity and intelligibility of the whole embedded system.

Profiler for Generic Simulators of Microprocessors
Wilczák, Milan ; Přikryl, Zdeněk (referee) ; Masařík, Karel (advisor)
This thesis presents design and implementation of profiling tool for newly created microprocessors. For microprocessor description specialized language ISAC is used which describes processor resources, instruction set and behavior. Final profiler is an extension to existing simulator and can be used for optimizing of both processor and its applications. Principle of the profiler is generating events by simulator and processing these events into statistics.

The FITkit3 Tester
Stehlík, Petr ; Strnadel, Josef (referee) ; Bidlo, Michal (advisor)
This work solves the problem of testing a certain set of ARM Kinetis Cortex-M4 \newline (MK60DN512ZVMD10) microcontroller modules on the FITkit3 learning platform (also known as Minerva). Specifically, it deals with the design of test firmware in the C programming language for automated testing, the design of a hardware module for testing platform input/output interfaces using the MCP23S17 integrated circuit and the design of a software with text-based user interface in Python3 for the testing control from a PC. The selected test set of modules are Periodic interrupt timers (PIT), Low-power timer (LPTMR) and Real time clock (RTC), further modules for serial data transmission via UART and SPI interfaces, speaker and GPIO ports. The created solution provides a comprehensive tool for analysing the functionality of frequently used modules on FITkit3, which automates the analysis process almost completely. The main benefit of this work is the facilitation of testing and a rapid detection of errors in a large number of kits.
