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.

Door control module
Šrámek, Jiří ; Burian, František (referee) ; Fiedler, Petr (advisor)
The thesis deals with development of the control module of a permanent magnet synchronous motor (PMSP) which is being developed as a reliable part of the platform door system. The whole electronics (including reliable, safe and information parts) will be a product of STARMON company. The paper fully describes the determination of requirements and limitations coming from the national standards involved. Furthermore, it describes the process used for the identification of PMSM parameters, the method used for controlling the PMSM by the original electronics and other generally known methods, while choosing the most optimal one for this application, including the process of designing appropriate controllers. After that, it deals with designing appropriate schematic and realization of hardware. The end of the thesis describes the structure of communication protocol, developed firmware as well as the developed PC application and its user interface.

Firmware for Multi-Unit Wireless Sports Timekeeping Device
Gál, David ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This paper describes the design and subsequent implementation of software for multi-unit wireless sports timekeeping device. Used hardware is based on a different thesis and is composed of a control, the primary unit, and end, secondary, units. Both types are equipped with 16-bit PIC24F microcontrollers and wireless communication is catered by RF modules broadcasting in the 868MHz band. The design is aimed primarily at wireless use of secondary units to measure time and to eliminate measurement errors associated with wireless transmission. It also deals with reducing the consumption of units and the use SD cards to store the measured times. Implementation is done in C.

Remote maintenance of the microcontroller systems
Vágner, Martin ; Hynčica, Ondřej (referee) ; Kučera, Pavel (advisor)
This thesis deals with methods of remote maintenance of microcontroller systems based on Atmel AVR family over the Ethernet interface and TCP/IP protocols. To create communication through TCP/IP, an embedded server NE-4100T is used. At the beginning, key features of the server and methods of handling with content of a program memory are discussed. The final solution is based on the bootloader method. It includes bootloader firmware and user program for PC. The hardware part covers design of interconnection electronics, DC-DC step down converter, real time clock and printed circuit board. The remote maintenance of program memory has been sucessfully solved, but the embedded server NE-4100T produces a problem with an auhentification without a sufficient solution.

Communication SW ARION
Kaczmarczyk, Václav ; Kašík, Petr (referee) ; Zezulka, František (advisor)
The main goal of this thesis is creating diagnostic software for analyse communication via protocol ARION. That software would record and store communication data which can be analyzed late and also allows direct communication analysis in real time. Except that there will be visualization functions, for effective representation of data (stored or real-time recorded). This software can be used either by net developers or by end-users like easy visualization software. Next point is describing communication protocol ARION and create developer’s handbook. The practical part of this thesis consists of two points. The first one is developing simple device which allows communicating via protocol ARION. In second communication firmware for that device is written and tested.

Diagnostic tool for SD card protocol
Frnka, Peter ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
The objective of this diploma thesis is to design and implement a diagnostic tool for communication protocol of SD memory cards. The diagnostic tool will be able to monitor and interfere with communication of an SD memory card. The hardware implementation will be based on platform with Kinetis K66 microcontroller. A PC application designed for windows is also a part of diagnostic tool. There is a conclusion of the diagnostic tool limitation at the end of the thesis.

Protection of highspeed communication systems
Smékal, David ; Martinásek, Zdeněk (referee) ; Hajný, Jan (advisor)
The diploma thesis deals with 128–bit AES data encryption and its implementation in FPGA network card using VHDL programming language. The theoretical part explains AES encryption and decryption, its individual steps and operating modes. Further was described the VHDL programming language, development environment Vivado, FPGA network card Combo–80G and configurable framework NetCOPE. The practical part is the implementation of AES–128 in VHDL. A simulation was used to eliminate errors, then the synthesis was performed. These steps were made using Vivado software. Last step of practical part was testing of synthesized firmware on COMBO–80G card. Total of 4 projects were implemented in FPGA card. Two of them were AES encryption and decryption with ECB mode and another two describe the encryption and decryption with CBC mode.

Generic BIOS Update Mechanism for Linux
Mariščák, Igor ; Šimek, Václav (referee) ; Kašpárek, Tomáš (advisor)
This work provides overview of creating of a simple driver for the BIOS flash memory by accessing the physical computer memory. Although, the BIOS is one of a system's core components, there is no standardized update mechanism approach. Purpose of thesis is to create module driver by taking advantage of existing interface subsystem MTD, to suggest and implement driver for one specific device to Linux kernel operating system. Also explains technique allowing write access to registers of the flash memory with utilization of configuration file.

Audiostimulation
Sobotková, Marika ; Walek, Petr (referee) ; Sekora, Jiří (advisor)
The aim of this bachelor thesis is to design a device for audio stimulation, which will be used during examination with functional magnetic resonance. The next aim is to familiarize readers with magnetic resonance and stimulation. Whole device is controlled by microcontroller from open-source platform Arduino, model Due. Hardware is based on a non-soldering contact field. There is also draft of printed circuit board. Software is represented by flowcharts. Algorithm is designed and realized in wiring Arduino's library (which belongs to Arduino). Microcontroller is controlled by graphical user interface made by MATLAB.

Testing equipment for small electrical motors and linear actuators
Červínek, David ; Vejlupek, Josef (referee) ; Grepl, Robert (advisor)
Aktuální postup testování je příliš zdlouhavý a nepřesný, zároveň není měření některých vlastností motoru vůbec možné. Hlavním úkolem zařízení je zrychlení a zjednodušení procesu testování spolu s možností otestovat všechny vlastnosti motorů. Realizace zařízení začala definováním požadavků zákazníka, dalším krokem byla analýza daných požadavků a návrh zařízení. Následovala výroba a programovaní firmwaru spolu se softwarem. Výsledkem práce je funkční přístroj schopný automatického testování sedmi základních typů motorů, měření všech požadovaných funkcí spolu s novou možností měření počtu tiků enkodéru, periody FG signálu z řídící elektroniky BLDC motorů a napěťové úrovně těchto signálů. Dalšími rozšířeními jsou možnost uložení výsledků z uskutečněných testů pro možné budoucí využití a možnost vizualizace proudu motorem. Uživatel je tedy schopný otestovat velké množství motorů v kratším časovém úseku a zároveň se o testovaných motorech dozvědět mnohem více informací než doposud.
