Microcontroller programming in GNU/Linux
Jančík, Martin ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
This project is dealing with programming problems of the micro-controllers Atmel AVR in the system GNU/LINUX. It demonstrates wide programming possibilities micro-controllers of the system GNU/LINUX not only for the programming tasks, but for upload program to 8-bits controllers as well. The Project is aimed at the software, equipped with a graphic user´s interface, conceivably at a software enabling its control from a console. Further more, there are programming methods for the micro-controllers Atmel AVR described here, a survey of programs for micro-controllers AVR within the system LINUX is comprised there, as well as the proposal of some simple serviceable application using the micro-controller – displaying of the system information from a PC on an external LCD screen.

Emulator of 3.5" diskette drive using RS232 and SD memory card
Sedláček, David ; Hanák, Pavel (referee) ; Pavelka, Ondřej (advisor)
This thesis deals with the design of the 3,5" floppy drive emulator with ATMEGA microprocessor unit. The emulator has been designed according to the principles of designing electronic devices, there is also object-control application and firmware for a microcontroller, which supports MFM coding. The thesis also lists all the formats of data stored or transmitted along with some flowcharts.

Design of Flow, Temperature and Pressure Measuring System
Macíček, Ondřej ; Čížek, Martin (referee) ; Sekora, Jiří (advisor)
This master’s thesis contains complete design of the complex measuring system for temperature, pressure and flow. Objects of measuring are pressure in rabbit’s heart ventricle, flow of the saline through the heart and the temperatures of physiological solution. Work is interested in programming of microcontroller and program for LabVIEW environment, which is used to view and export relevant data related to measuring. Text also contains technical documentation of functional sample of measuring system.

Position system design
Balogh, Jaroslav ; Čížek, Martin (referee) ; Čech, Petr (advisor)
The purpose of this diploma thesis was to explore possibilities, design and build 2D position system driven by PC via USB. ATmega16 and FT232R were used as the most important parts of hardware solution. Software for control of the position system was designed in C++ Builder and it can run under MS Windows XP. This work is based on semestral thesis and in future can be used in other applications or modified. 2D position system will be later used by UBMI in education and scientific applications.

Biological Signal Generator
Kadeřábek, Jan ; Čech, Petr (referee) ; Sekora, Jiří (advisor)
This semestral thesis describes signal EKG, it’s origin, evaluation and device for his generation. After identification with standard course of EKG signal, was such as signal created in program language Matlab. It’s consisting of 10 sinus courses, where each of them has it’s own frequence, start phase and amplitude. Each of this part of EKG signal is beat frequence variant. Rates of it’s durations and sizes were fixed from medicin literature. Such as created program were rewritten to program language C and is basic of main program, which control signal processor. Finally was propoused preparation, which will be generated this signal. Outcome of this thesis is teoretic treatise about signal EKG, created program for generation of this course include part control and machine doing realization of biological courses.

Control of graphic OLED display with Atmel microcontroller
Bartošík, Vladislav ; Lattenberg, Ivo (referee) ; Hanák, Pavel (advisor)
This Master's thesis deals with design and a realisation of a device controlling an OLED display, Densitron DD-25664-1A. This display has a resolution of 256 x 64 pixels and allows displaying of 4-bit grayscale. The proposed utility software implements the initialization and termination functions, two sets of fonts { Latin and Greek letters and functions for rendering graphics and text. The result of the project is a device with the controlling software.

Design of evaluation network for in-vehicle networking communication chips
Kupčík, Ondřej ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
Cílem této diplomové práce bylo navrhnout moduly určené k demonstraci a testování některých obvodů, používaných v automobilové technice. Jedná se o LIN transceiver NCV7420 a osmivýstupový výkonový budič AMIS-39101. Návrh spočíval ve vybrání a popisu parametrů vhodných podpůrných obvodů, vytvoření celkového schématu a navržení desky plošných spojů tohoto modulu s ohledem na kompaktní rozměry a předpokládané testy. Dalším krokem byla tvorba firmware řídicího mikrokontroléru (C8051F344), jež zajišťuje LIN komunikaci, řízení budiče a základní monitorovací funkce. Poslední část popisuje software pro hostitelský PC umožňující komfortní řízení sítě složené z těchto modulů. Pro úplnost byl tento projekt doplněn o přehled vlastností sběrnice LIN a metodiky testování LIN transceiveru z hlediska funkčních parametrů i některých EMC měření. V příloha obsahuje kompletní schéma modulu, výkresy desek plošných spojů, seznam řídicích příkazů a fotografie modulu.

Onboard computer for status and functional parameters evaluation of internal-combustion engine
Jaroš, David ; Legát, Pavel (referee) ; Kuchta, Radek (advisor)
This thesis deals with design and realization of the onboard computer for evaluating functional parameters and status of the gas engine. Designed solution is consisted of two main parts. The first part is measuring unit whose obtains actual information on engine especially consumption of fuel, rotate per minutes and temperature of engine head. The second part of the solution is formed by pocket computer with appropriate software. The application for the pocket computer processes data from the measuring unit and from GPS receiver, which is integrated in pocket computer. Wireless bluetooth technology is used for data transfer between measuring unit and pocket computer. The application in pocket computer displays and records each of obtained and computed data.

Microcontrollers programming possibilities
Šubrt, Stanislav ; Kovář, Jiří (referee) ; Houška, Pavel (advisor)
This work is focused on inner structure and programming possibilities of microcontrollers. The work goal is to describe inner structure of microcontrollers from the programmer’s point of view, find out advantages and disadvantages of their programming in Assembly language, C language and higher-level languages. Code portability between different microcontrollers’ families and architectures is discussed further.
