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.

Real-time Control of Ball on Wheel Model
Krejčí, Roman ; Otava, Lukáš (referee) ; Hynčica, Ondřej (advisor)
This diploma thesis deals with control the Ball on the wheel system in real time. In the first part there is made mathematical model of system, which is described by state equations. Then the laboratory model of Ball on the wheel system and its parts are described. The laboratory model consists servo drive, servo amplifier, microcontroller with real-time operating system and distance sensors. In the practical part of the thesis there is designed control of system by linear quadratic regulator and its implementation with control peripherals into microcontroller with real-time operating system. Ball on the wheel system is controlled by microcontroller, which sends a commands to servo amplifier by CAN bus.

6 Axis Manipulator Control
Semrád, Michal ; Chromý, Adam (referee) ; Hynčica, Ondřej (advisor)
This master thesis discusses about designing and realization of a control system for a 6-axis robotic arm. The controlling system consist in a microcontroller LPC1756 with its firmware implemented under the Real-time operating system FreeRTOS and GUI application, running on a PC. The Microcontroller communicates with the PC through a serial line via SLIP protocol. Theoretically, it will deal with an explanation of the important terms, and describes the used robotic arm and its controlling unit. The practical part describes kinematics problems solving, firmware’s realization and GUI application.

Features real-time operating system for LabVIEW
Válek, Petr ; Beneš, Petr (referee) ; Čejka, Miloslav (advisor)
This thesis deals with certain properties of real time operating systems (RTOS) Ardence PharLap ETS, WindRiver VxWorks and LabVIEW RT module. Three methodologies of RTOS quality comparison are proposed, two of which are practically tested with described experiments on CompactRIO hardware from NI. Furthermore, there is explained need for RTOS usage and experimental comparison of jitter error influence on total harmonic distortion THD defined by two definitions.

Self-service station for charging of electric automobiles
Kubizňák, Jan ; Fojtík, Pavel (referee) ; Kučera, Pavel (advisor)
The subject of this diploma thesis is a creation of SW for the self-service charging station of ELNICO Ltd. company. The work consists of two main parts. The first part contains an overview of general charging stations for electro cars at current market. After this the prototype of the ELNICO system is described. It's main components and the control system realized by the development kit DK-LM3S9B96 are characterized here. The real-time operating system FreeRTOS, that is used by the kit, is also specified. The second part of the document deals with the SW design and realization. The thesis describes the structure and the main modules of the program. The functionality is then demonstrated by photos of running application.
