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.

In-System Programmer for ICSP Interface of Pic Microcontrollers
Doležal, Pavel ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This thesis is dealing with a design of programming device with the expected use for Microchip PIC 16F and 18F microcontrollers. Individual chapters are dedicated to aspects of circuitry, printed circuit board design and user software tools. The proposed device is based on PIC18F67J50 microcontroller, graphic LCD diplay, and memory card interface. Design can be easily adjusted in order to support wide range of devices. Microchip's In-Circuit Serial Programming protocol is described with focus on previously mentioned family of devices. Working prototype of the programmer is attached to this thesis as a demonstration of a practical outcome.

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.

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.

Automated measuring device for testing ELNEC programmers
Pražák, Jiří ; Štohl, Radek (referee) ; Šedivá, Soňa (advisor)
This thesis deals with the verification of parameters of Elnec BeeHive304 programmers. First, the reader is briefly introduced to the Elnec BeeHive304 programmer. Much emphasis is placed on the previous manual parameter verification. The aim of the work is to design and implement possible solutions for automation of the measuring process. In the main part of the thesis, two prototypes of a suitable automatic electronic measuring instrument for automated parameter measurement of the Elnec BeeHive304 programmer are designed and implemented.

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.

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.

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.
