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.

Design and construction of MIDI interface for sensor strings
Korytář, Matěj ; Přikryl, Lubor (referee) ; Jirásek, Ondřej (advisor)
This work focuses on problematics of MIDI converter design and construction for cimbalom. There is briefly described acoustic musical instrument in terms of tone creation and construction. Further is discussed possibilities of string sensing or other ways to capture performance. In the following chapter is described MIDI protocol in terms of history, interface and types of transmitted messages. There is also said requirements for converter's chip and way to connect it. Further is described a method of converting signal from sensors and following coding to MIDI protocol including used program with detailed specifications. In conclusion is discussed several future extension.

Recoil forces measurement after shotaVibration Test Stand
Rozum, Stanislav ; Kubinec,, Peter (referee) ; Frýza, Tomáš (advisor)
The thesis describes design and construction of vibration generator driver. The device is controlled via standard Ethernet interface and allows user to change parameters of generated function in PC application which reads and evaluates frequency and amplitude from real-time measured data while the test is running. In the introduction, vibration tests and choice of generators and power amplifiers are described. Next part is focused on every aspect of the hardware design. Last two chapters implement firmware for all three microcontrollers and software for PC application.

Temperature Measuring in Wellness
Gábriš, Michal ; Žaloudek, Luděk (referee) ; Bartoš, Pavel (advisor)
This Bachelor thesis deals with creation of operation program for digitally calibrated thermometer measuring two temperatures, which can be used in wellness centers. The thermometer operates in two modes, the mode of measuring and displaying of water temperature, and the mode of linear digital calibration, in which the temperature sensors are set. The Bachelor thesis contains both the description of used hardware components, and software solution implemented in assembly language. This device is already in commercial use.

USB Host with PIC Microcontrollers
Kučera, Pavel ; Janoušek, Vladimír (referee) ; Hanáček, Petr (advisor)
The aim of master thesis is implementation of USB host in a microcontroller PIC. The thesis contains description of ways of peripherals to computer connections with detailed description of USB bus. There are also discussed several approaches in implementations USB host for embedded systems. A concept of layered USB host system is designed on the basis of analysis of the state of the art. Finally, the designed system is implemented in microcontroller. Resulting firmware of development kit is tested on real USB device.

Company policy for electronical business - credit cards
Šulc, Vladimír ; Dvořák, Jiří (advisor)
This dissertation work deals with the subject of a company in the area of e-commerce, which represents short-term or long-term plans in controlling the financial relationship toward the outer environment but also inside the company. The problem of possible abuse of credit cards is briefly analysed as well. The impulse for choosing this topic was increasing number of falsification and abusing of credit cards. When this subject is analysed in detail, the problem connected with lack of information on this particular area of crime inevitably appears. Clients of individual banking institutions often do not have even the basic knowledge about the ways their cards could be abused or misused. This is why the question of certain, at least minimal, basic information campaign done by the banks, which are supposed to protect the financial means of their clients. This dissertation work sets its goal in creating the methods of investigation of credit cards abuse not only in the Czech Republic but in the growing system of countries of Schengen Treaty and European Union. The benefit of the work can be seen in the level of theory as well of practice. The theoretical part of the work contains the analysis of the current situation of scientific knowledge in the area of information and communication technology of companies, which is implemented into information systems. Then the advantages and disadvantages connected with this kind of e-commerce are assessed and the specific opportunities for abuse of these media of payment are characterised. The problem sees mainly in writing a specialised publication, which would deal with the problem of abuse and falsification of credit cards and its possible use would be at police academies. Its main part should be the characteristics of particular forms of cards forging and also possible identification of these forgeries. This book could also help in prevention and inform clients of financial institutions about the ways of credit cards abuse. In the practical part, which concentrates on the Czech and foreign market, the author sets the basic premises for realisation of safe business of companies in the Czech Republic and its procedures. Furthermore the reasons of e-commerce abuse in the Czech Republic are analysed and results of quantification research presented. This was concentrated on ascertainment of reason of low interest in information among the public. In the conclusive part of the work the whole problem is summarised and there are also outlined perspectives and possibilities of further development

Implementation of 8-bit microprocessor into FPGA chip
Walletzký, Ondřej ; Dvořák, Vojtěch (referee) ; Bohrn, Marek (advisor)
This thesis deals with design of microprocessor compatible with one of 8-bit microcontrollers manufactured by Microchip company. Theoretical part of this thesis analyzes architectures of 8-bit PIC microcontrollers, picks one of these microcontrollers and describes its architecture and function of its subcircuits. Practical part deals with design of architecture compatible in terms of instruction execution, internal data flow and subcircuit behavior, all this to achieve the best possible program portability from target microcontroller. The last part of thesis describes method of processor implementation into FPGA chip and mentions potential design differences for ASIC implementation. It also deals with verification and method of programming.
