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.

An external pulse generator for neuromodulation
Flídr, Lukáš ; Čech, Petr (referee) ; Chmelař, Milan (advisor)
The main objective of this work is to explain and familiarize with neuromodulation, its use and possibilities of its application in current medicine. It will also focus on the basic configuration and the block concept of an external generator and the time courses of the generator are described. In the first phase the base of neuromodulation is explained, then the main application, the implementation of this technology and the possibility of its application in modern medicine. Further to the work we will find an overview of equipment used for neuromodulation. The other part is focused on a design of an external generator using a MOTOROLA Nitron HC08 series microcontroller, its configuration and finally description of the time courses (impulses) from the device, that are used for neuromodulation.

Developmental kit width AVR microcontrollers
Dostál, František ; Čížek, Martin (referee) ; Dlouhý, Jiří (advisor)
The topic of my bachelor´s thesis is the implementation of development kit with AVR ATmega16 processor and creation a simple program to verify the functionality of all the peripherals. Part of the solution is the JTAG programmer. Programs are developed in C language and tested with all necessary peripherals microcontroller, timer / counters, A/D converter, ports, USART unit. Also there were programms developed, that ensure scanning the keyboard matrix, LED lighting, crystal transducer activation, measurement using tilt sensors ADXL 330, communication with the LCD and easy connection to a mobile phone.

Industrial programmer Atmel AVR microcontrollers
Gryžboň, Jan ; Hanák, Pavel (referee) ; Pavelka, Ondřej (advisor)
The aim of this thesis is to design and implement an industrial programmer AVR microcontrollers from Atmel. The first section provides the theoretical knowledge of the AVR microcontroller. Furthermore, comparison of methods for programming the microcontroller and the selected method is an analysis of the speed of programming. The following is the entire design of industrial programmer which is implemented in the programming environment Eagle. In the penultimate part of the proposal is designed PCB. The final section is devoted to the revival of the programmer and programming.

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.

External pulse generator for neuromodulation
Flídr, Lukáš ; Říčný, Václav (referee) ; Chmelař, Milan (advisor)
This thesis deals with the treatment of chronic pain by using neuromodulation, where a external generator is used in a trial period. In the first section the principle of pain management is described and then the main nature of neuromodulation. The possibilities of chronic pain suppression are described, where we are mainly dealing with neurostimulation (stimulation with electric current). For better understanding, examples of neurostimulation usage are shown, where and in what problems it is used. Because this work deals with an external generator for a trial period (a trial system), the possibilities of testing electric impulses are described, which are then used in a implantable generator IPG. The requirements for such a external generator are also described, which are important for the design of such a device. The design of the device is firstly modeled by a block scheme, where function of the separate blocks is described and afterwards, the entire design of the external generator for neuromodulation is given. The test sample of the external generator is manufactured and tested.

Multifunction data acquisition, measurement and control device
Trávníček, Ivo ; Vlachý, David (referee) ; Grepl, Robert (advisor)
The thesis deals with and tests the Multifunction data acquisition, measurement and control device. The unit is based on the microcontroller ATmega, which was programmed in the language C. The unit contains functions for the measurement of physical quantify, filtering record, regulation of the dynamic systems and communication with PC. Configuration of the unit is real-time in special software created in the language Matlab or by a terminal. The purpose of the unit is controlling a DC motor by the PID regulator, long-term measurement of temperature or measurement of acceleration by an accelerometer.

Recruitment and selection of employees in selected sectors
Lukačovičová, Estera ; Němec, Otakar (advisor) ; Stříteský, Marek (referee)
The aim of this Bachelor thesis is to analyze and compare the processes of recruiting and selecting of employees in the specific selected companies. The theoretical part is an introduction into the topic that mainly describes the differences between the profit and non-profit sector. Followed by the description of the recruitment and selection of the employees from the identifying the need of a new employee to the final selection and acceptance or non-acceptance of any of the candidates. The practical part introduces a company eProvement and a voluntary organization Okamžik, further precise description of the processes of recruiting and selecting of the employees in both companies. In conclusion, there are compared both activities and suggested the recommendations in order to improve these processes.
