Simple one-chip microcontroller programmer
Verner, Lukáš ; Číž, Radim (referee) ; Daněček, Vít (advisor)
The main purpose of my bachelor thesis is acquaint with issue programming of Atmel AVR microcontrollers and to create a simple chipprogrammer with component units like LEDs, switches, LCD display, DA converter for testing and development. The first part deal about questions of theory programming memory inside microcontrollers and descrption of programming algorithm. The memories is possible program in three way. The most used method is method call „In System Programming“ ISP. This method provide easy and fast manupulation. Order method of programming memory require 12V supply. These method are parallel and serial high voltage programming. The concept of programmer is design to all method of programming memory. From previous information about programming memory was written source code of program to control programmer that receive command from computer and ensure performing of right algorithm in target microcontroller. In the next chapter is clarified design of hardware items and there is the simple user manual of items and installation of programmer. The final part of thesis explains how to use programmer's tworowconnectors and setting jumpers for programing in daily work. In attachments are electrical scheme, list of devices, printed circuit board, files of circuit board and scheme in Eagle format, source code and binary program to control microcontroller of simple chipprogrammer. These attachments are needed for make a chipprogrammer.

Control of multiple-steer vehicle
Krsek, Jiří ; Kopečný, Lukáš (referee) ; Šolc, František (advisor)
The subject matter of the bachelor thesis is a creation of functional model of mobile robot equipped with multiple-steer chassis. The robot will have its own control unit consisting of 32-bit processor and wireless communicatin unit, which enables the contact with superset system. The superset system serves as visualization interface robot - operator and enables to enter the data for requested movement of robot. The calculation of movement of each actuator is ensured by control unit of robot.

Remote control of targets
Tkáč, Stanislav ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
The task of this work is to make a functional device, that is intended to close only one of several (38 to 55) of electromagnetic valves. Which valve is going to be switched is elected either of the push-button keypad, or from a PC via RS 232. Equipment must be made using one or more PIC processors.

Real Time Recorder of Events
Nezval, Tomáš ; Kosina, Petr (referee) ; Šandera, Josef (advisor)
In this bachelor project I have been working on the design and construction of a device for storing 8 bits information on a SD/MMC memory card. The main problems are: storing of data on a memory card by microcotroller PIC in a way that will be readable on a PC (TXT file); implementation of file system FAT16; storing the data in defined time intervals by RTC (real time circuit), and ensuring the overall design enables minimal consumption of the battery power supply.

Autonomous programmer of AVR microprocessors with Ethernet connectivity
Verner, Lukáš ; Daněček, Vít (referee) ; Kravka, Martin (advisor)
he main purpose of this semestral thesis is to get to know programming of Atmel AVR microcontroller, working with SD/MMC cards, working with ethernet (TCP/IP) to create a standalone programmer of AVR microcontroller with ethernet connectivity. The first part deals with the questions of programming theory of memories inside microcontrollers and description of programming algorithm. The most used programming method is called „In System Programming“ - ISP. This method provides easy and fast manipulaton. Concept of this programmer is designed for this ISP method. In this thesis is too explain how to work SD/MMC card and file systém FAT16. This knowledges are necesary to store binary program inside standalone programmer. In final part and in attachments there is hardware design, electrical scheme, bill of materials, printed circuit board.

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.

Micro cooling with Peltier cell
Brázdil, Marian ; Bogdálek, Jan (referee) ; Pospíšil, Jiří (advisor)
This work concerns detail description of thermoelectric cooling modules, principles and practical utilization of thermoelectric cooling modules. Experimental part of this work studies computer cooling. Distribution of temperature at the cold and hot side of the thermoelectric cooling module as a function of load of a processor was measured. The obtained temperatures were compared with the common cooling methods.

Technology Development of Mobile Devices
Stejskal, Jiří ; Benáčanová, Helena (advisor) ; Řezníček, Dušan (referee)
This thesis is focused on the technology of mobile devices. In the first part I analyse the technical parameters of the mobile device in detail, I mention each parameter and its importance, pitfalls and benefits. The second part is focused on mobile operating systems, especially iOS, Android and Windows Phone. The operating systems are analysed from the perspective of technological complexity, which builds on the analysis of the technology of mobile devices. The third part consists of future prediction. I describe hypothetical future development for both of previous parts of my survey. Approximate future development is mentioned in each chapter of of both first and second parts. The main benefit(contribution) of this work is the compact view on the issue of the technology of mobile devices. It helps reader to make a complex overview of the evolution and possibilities on the current mobile devices market.

Hardware for Small Companies
Bešta, Václav ; Měsíček, Libor (advisor) ; Pitka, Lukáš (referee)
I have been encountering the concept of hardware for many years and I am really interested in it. That is why I have decided to deepen my knowledge in this subject field and to write the thesis named Hardware for Small Companies. At the present time, when the modern technologies are used in many departments, is hardware becoming more and more demanded goods. Also the fact, that hardware as a structural unity cannot be upgraded to more efficient unit, may assist. If the user wants to upgrade one concrete part, he can't do anything else than to buy a new, upgraded unit. The spectrum of the hardware conception is very wide and I pursue mainly the part, which can be used in the small company environment and its accessibility at the Czech market. Then I mention the history of hardware and its prominent world producers. Writing the theoretical part, I used web-based sources and the scientific literature, that is concerned with the conception of hardware the most. Writing the practical part, I made use of the knowledge that I got from my studies and from the online offers of the prominent hardware suppliers. The main contribution of the thesis is the project described in the practical part. This project will serve as a rough basis for getting a capital grant for the creation of the new training center in the pension Dubina in Litoměřice.
