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.

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.

Electronic attendance book
Nezval, Tomáš ; Macháň, Ladislav (referee) ; Šandera, Josef (advisor)
This Master’s thesis deals with analysis of available identification chips and the design electronic attendance book that these chips will use and store the measured information to a file on a memory card. One of the tasks is to compare different kinds of identification cards and chips, and select the most appropriate type for the implementation process. Additionally, the work described the FAT file system, which is used for data storage card.

Controlled power generator of current impulses
Gabriel, Viktor ; Vrba, Kamil (referee) ; Rampl, Ivan (advisor)
The goal of this thesis is to design and realise microprocessor-controlled generator of current impulses, which are being brought in induction load. Thesis contains description of individual functional generator parts, mainly microprocessor program equipment. The text also aims for inductor design as an induction load and other solutions of power parts with the selection of the most suitable one. The generator of current impulses itself is realised on two-sided printed circuit board.

Development board with 32-bit ARM-based processor
Jůn, Lukáš ; Šebesta, Jiří (referee) ; Frýza, Tomáš (advisor)
The content of this thesis is to create a detailed description of 32-bit ARM-based processors. Reader will be inform about the each one of the family of ARM-based processor, about the options of creating applications for these CPUs. The Applications are commonly developed by using the C/C++ language. This text also deal's with the development environments. These tools are making easier the development of new applications. This thesis also contains a complete design and description of development board with Atmel AT91SAM7S64 MCU (with sample of source code included).

Periphery tester with Single chips AVR ATMEL acquisition
KROUPA, František
The objective of this Bachelor?s thesis was to design a tester of I2C, SPI and 1WIRE interfaces. In the theoretical part of the thesis, these interfaces as well as protocols are described. In the practical part, a design of the device and description of its functions are presented. The device is composed of two main components, a "master" (PC visualization of tester controlling) and "slave" (microcontroller ATmega-8 and FTDI 232). Function of the device was verified in practice.
