Library for graphic objects for microcontrollers Atmel AVR and graphic displays
Skopal, Miroslav ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
This bachelor’s thesis is concerned about the graphic LCD display control by the Atmel´s AVR microprocessors. Toshiba T6963 controller is described in detail. The overall result of my bachelor’s thesis is the modular library written in C language (GCC). It provides a set of functions for simple graphic objects and controls drawing. The library is designed as a multi - layered one. It supports the usage of different LCD display controllers without any extensive program code modification.

Minidarpa robot - electronic layout design
Groulík, Tomáš ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
Bachelor`s thesis is bent on problems mobile robotics. In forepart is genarally circumscribed architecture AVR and individual used microprocessors. Next part is intend for distance evaluation by the help of ultrasonic sensores and concrete description of used modulus. Last part is specialized in motor control and regulation of DC motor. There are described possibilities of motor control by the help of PWM and used draft of motor control and projecting of regulator.

Design and making of low-frequency power amplifier in class AB
Dušek, Martin ; Kratochvíl, Tomáš (referee) ; Brančík, Lubomír (advisor)
In this bachelor thesis I am occupied with low frequency amplifiers, theirs important parameters, classes and with integrations end-level. Next I am occupied with miscellaneous types of preamplifiers and additional circuits. There are simulated schemes of corrective preamplifier, protections scheme and high power amplifier in PSpice software in this thesis. These schemes and next additional modules are connected with DPS. This thesis contains result of measurement and photo functional sample.

Microprocessor Controlled Power Measurement System for Frequencies below 10GHz
Klíma, Martin ; Lukeš, Zbyněk (referee) ; Urbanec, Tomáš (advisor)
The aim of this work is to design a microprocessor controlled power measurement system which is based on the logarithmic detector AD8317, then to create a printed circuit board and to test its functioning. The logarithmic detector AD8317 is acceptable for measurement of high frequency signal’s power of the level between approx. –55 dBm and – 3 dBm in the frequency bandwidth of 1 MHz to 10 GHz. Its output provides DC voltage which is corresponding to the decibel-scaled level of the input signal. This is suitable for A/D conversion and digital processing by the microprocessor. The result of the work is a complete measurement system.

Communication system for the blind - the fixed part
Botko, Ondřej ; Koton, Jaroslav (referee) ; Herman, Ivo (advisor)
The thesis deals with problems of navigation blind in buildings, where is not possibility navigation by GPS (Global Positioning System). This thesis contain resolution through the use of communication units, placed in floor of buildings. This comunication units, equipped with receiver and transmitter, can give direction for blind by send own identification to transceiver in speciál stick (the thesis does not contain solving of the stick), which can information blind of position. Two comunication unit solution are available, that differs by using component part. The main difference is in use control unit of circuit. First circuit use as control unit ATAR862-3 (microprocessor and transmitter in one case) and the second one use microprocessor ATmega 8L. Both component made by Atmel corporation. Circuit with ATmega 8L is more exacting on curent consumption, but solving this problem is available and communication unit has low pretensions and long life. The part of thesis is program, which solving communication protocol for no-problem communication between unit in floor and special stick.

Present-day Programming Method of Microcontroller
Medla, Eduard ; Matyáš, Pavel (referee) ; Zuth, Daniel (advisor)
This bachelor thesis is dedicated to modern methods of programming microcontrollers. In this work are examined some programming languages, various programming environments and graphic editors. In every methods of programming are explained their advantages and disadvantages. Here are two examined methods of loading program to microcontroller, so called flashing. Choosed method is programming language C, which was used to programme two-state regulator with hysteresis in environment AVR Studio 6.2.

Manipulator control via microcontroller
Šíl, Petr ; Liška, Radovan (referee) ; Zuth, Daniel (advisor)
This bachelor thesis is dedicated to the control of the manipulator by microcontroller. It is a scale model of the manipulator, which will demonstrate the functions of a similar manipulator in the real time practice. The design of the manipulator consists of two parts, the mechanical part and driving part. In each section were chosen suitable parts to fulfil requirements of desired functions. The functionality, simplicity of manufacturing of all sections, the price and simplicity of control were the main criteria during the design of the manipulator. The system utilised ATmega 128 and development environment AVR Studio 4 to control and test microcontroller ATmega128.

The intelligent wiring and application of Atmel AVR microcontrollers
VOLF, Jiří
The aim of the thesis is to explain and introduce the indiviudal components and control proceedings in the systems of automatic control of intelligent houses. The thesis is divided into three parts. In the first part I deal with the general description and structure of the house automatic systems, their availability and application in wiring practise. The second part is focused on the proceedings used in RC5 infra-red area and the most used X10 PowerLine protocol and its processing by AVR microprocessors. The third part is concentrated on the practical construction of a module with a microprocessor enabling the development and education of user applications for the substance of the automation system and that extend it in other possibilities of communication such as ethernet and WiFi networks, eventually GSM mobile network.

Microcontrollers Atmel AVR, use hardware development kit STK 500 and AVR Studio development environment and programming language Bascom
VOLF, Jiří
Goal of this work is a description of 8-bit microprocessors of AVR series with RISC architecture, instruction set and programming environment, Bascom and AVR Studio. Furthermore, this work deals with communications with the microcontroller environment, focusing on a specific type ATmega32. The work is divided into four parts. The first section deal with the general history and development of programmable logic circuits. The second part is attended to the micro{$\neg$}controller ATmega32 its basic parameters, HW core and instruction set. In the third part we deal with a comparison of software programming tools and Bascom AVR Studio and possible cooperation with a hardware development kit STK 500th The fourth part is focused on practical demonstration of communication and MCU IPchip Nano{$\neg$}SocketLAN using a set of AT commands. The design module allows any device equip{$\neg$}ped with TCP / IP communications.
