Modular RGB LED display with Ethernet
Zemánek, Petr ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with an electronic circuit and a PCB of a modular RGB LED display with the Ehernet interface. Firstly, author describes a RGB colour model, features of RGB LED displays, ways of control them. The next chapter contains a short description of the Ethernet interface, UDP and TCP protocols and a lwIP TCP/IP stack. The last theoretical chapter is an introduction to ARM Cortex-M3 and Cortex-M4 based microcontrollers. The next chaper is deals with a hardware design of the modular RGB LED display. The device is designed to be modular. Individual devices can be combosed together and create a larger display. Data from the Ethernet interface will be displayed on the RGB LED matrix, resolution of the matrix is 32 × 32 (1024 diodes). A refresh frequency is 100 Hz, a color depth is High color (16 bits) and a scanning 1/16 (two rows is driven at the same time). The next chapter describes the firmware for the RGB LED display, all its logical parts including a web page. Author also created the PC application, which sends pictures using UDP protocol to individual modules.

Design of the user-friendly touch screen GUI and a physical connection to an existing simulation hardware device
Husar, Jan ; Kaczmarczyk, Václav (referee) ; Štohl, Radek (advisor)
Práce uvádí základní informace o průmyslové sběrnici AS-Interface a popisuje její funkce. Dále se zabývá rozšířením stávajícího FTZ AS-Interface Slave Simulátoru o dotykový display, který značně usnadní ovládání tohoto simulačního nástroje. Je zde nastíněn návrh a řešení uživatelského dotykového rozhraní k tomuto simulátoru s použitím Amulet LCD modulu STK 480272C. Vývoj tohoto rozhraní je proveden pomocí GEMstudia, softwaru firmy Amulet Technologies a grafických programů. Dále tato studie pojednává o softwarové úpravě FTZ AS-i Slave Smilulátoru. Jedná se o úpravu řídícího FPGA v jazyce VHDL zajišťující komunikaci s dotykovým displejem. Poslední kapitola se týká problematiky spojené s návrhem uživatelsky přívětivé aplikace.

Compiler of source code for SIMATIC PLC
Kubát, Zdeněk ; Kaczmarczyk, Václav (referee) ; Pásek, Jan (advisor)
The thesis discusses an independent compiler for STEP 7 and WinCC V7.0 applications of the SIEMENS company. The compiler processes source files generated in STEP 7 and subsequently saves the processed data in .xls type intermediatefiles. The data of the intermediatefiles serve as source data for functions generating files with tags to be imported into WinCC V7.0. The compiler was created using the C# programming language in Visual Studio 2010.

Use of the software PLC in thermal engineering of buildings
Hubený, František ; Kaczmarczyk, Václav (referee) ; Pásek, Jan (advisor)
This presenting master’s thesis deals with a problem of digitaly controled room temperature using the software PLC. The result of this work was creating of an algorithm to control temperature on the requested leve ofl setpoint, minimizing operating costs of the building. The PLC softwares from different manufacturers were analyzed and compared with conventional PLC. The testing facility was disigned and used to control the temperature in the room and data visualization. Room temperature was regulated by PS controller or two point regulator.

Analog system SW simulator
Košta, Ondřej ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
This Master’s Thesis focuses on development and realization of analog system software simulator for simulation of various kinds and orders systems and for function verification of microcontrollers’ control systems. The development and realization of PSD controller is part of this thesis as well. The simulator is written in C++/CLI programming language which combines fast execution of native code and provides an advantage of managed code which has its execution managed by the .NET Framework. The data acquisition is performed via National Instrument’s USB multifunctional DAQ. The PSD regulator is realized by using modern ARM processor architecture.
