Arduino based serial bus decoder
Giertl, Juraj ; Lattenberg, Ivo (referee) ; Krajsa, Ondřej (advisor)
This project deals with possibilities of capturing and decoding data from different serial buses. Then describe ways of automatic recognition of the buses. The project include hardware and software development of device used for capturing data from different serial buses such as SPI, UART and I2C. Characteristics of these busses are described in detail. Device is design as shield to support Arduino boards. The Shield includes four fully isolated inputs and five non isolated imputs for capturing data, Ethernet interface, SD card and two display interfaces witch supports up to ten displays.

Design of LED lighting for industrial camera systems
Svoboda, Martin ; Honec, Peter (referee) ; Janáková, Ilona (advisor)
The bachelor thesis deals with the development, design and construction of multispectral lighting for industrial camera systems. The lighting is conceived as a modular device consisting of two parts - a control unit, which can be communicated primarily through the Modbus TCP / IP protocol, which powers, controls and collects information about the connected lighting unit. The illumination unit is equipped with 64 intelligent RGBW light emitting diodes located in an 8x8 matrix and one control diode opposite to which light intensity sensors are placed to give feedback on the color and intensity of the light. There are two temperature sensors located between the LEDs to check the temperature of the lighting unit. Both units are housed in a robust aluminum chassis. The control unit contains a microcomputer programmed in C language

Universal Analyzer of Serial Buses
Gajdoš, Matúš ; Hanák, Pavel (referee) ; Sysel, Petr (advisor)
The purpose of this master’s thesis is to design and to realize the universal analyzer of serial buses. At the beginning there are described in detail specifications and properties of buses IC, SMBus, PMBus and of the UART interface. The second part is targeted especially to design and to realize the control unit, which is the main part of the whole analyzer. It provides connecting to the unknown bus, to buses IC, SMBus, PMBus and SPI and to the UART interface. The main part of the control unit is the microcontroller PIC24HJ128GP204, which partially analyses connected bus. In the next part there is created the user application for PC, which controls and sets the control unit and receives from it partially analyzed data through the USB port. These data are used for the rest of the analysis that is done by the user application. Results may be presented to user in graphical or text form. The user application provides export of results into some of image formats. Supported formats are PS, SVG, PDF, PNG and BMP. In case of the control unit is not available, the user may choose the simulator to simulate some functions that the application provides. It supports simulation of the analysis of the unknown bus and the IC bus. The user application also contains the function of the generating own signals. Signals can be created interactively by using the mouse in the graphical representation of this signal. They can be sent to the control unit and after that it applies them to output. This function is not supported in current version of the control unit software. The user application includes some items, which do not have implemented any methods and they are prepared for the future upgrading of the analyzer. It means especially user controls and components for signal conversions between any buses.

Security system for family house
Sohr, Martin ; Macháň, Ladislav (referee) ; Jaroš, David (advisor)
This thesis deals with complete theoretical design of security system for a family house, from the selection of technologies, security principles and selection of elements, theoretical suggestions of their placement to practical realization. I this thesis, securing of entry points, such as doors and windows, is done by magnetic contact sensors. Windows are secured also against breaking of glass. Inner space is secured using motion sensors. Further, the function principle of optical latches as secondary securing element of inner space is explained. The designed security system implements a central control unit, which is able to provide status information on all security elements to the host system. IQRF wireless communication operationg in licence-free is used for communication among elements of the security system. GSM SIM9000 module is used for communication with the security system.

Electronic thermometer and humidity meter
Lapáček, Petr ; Chmelař, Milan (referee) ; Lattenberg, Ivo (advisor)
This master´s thesis deals with the design of measuring station used for the temperature and humidity measurement. There is a theoretical basical description of sensores for temperature and humidity measurement in the first part. Furthermore I deal with a theoretical design of measuring system, especially with types of materials and possibilities of communication between these parts. The main part of thesis is about communication on buses I2C,UART, SPI, RS485. There is a description of function procedure of particular integrated circuit, moduluses which are used in task in the next part of thesis.In the practical part I was engaged in a functional design of autonomous system for the temperature and ralative humidity measurement. Data could be presented by the computer after connection with the station. There is a description of testing the particular circuits and the full description of function particular blocks of system in the task. I have used the program called Eagle for schemes and printed wirings designing. The copy is placed on CD ready for next using. In the last part of thesis is a brief description of program algorithm "Meteostanice", which I have created for data presentation. There is an illustration of measuring results in these last part. The task is completely ready for the realization of autonomous system of weather station with its own memory.

Generic logic analyzer
Tajč, Martin ; Povalač, Karel (referee) ; Kubíček, Michal (advisor)
The aim of the project is to design a generic logic analyzer based on an FPGA. The analyzer should be able to analyze protocols such as I2C, SPI, RS232, RS485 and GPIO. The captured data can be observed using an embedded graphical display or using a PC. The PC can be used to control the analyzer and to save the captured data. The thesis is divided into several parts. First, the basic structure of the analyzer is described including detailed description of its particular components. Later on, the most common protocols that can be decoded using the analyzer are described. Finally, the FPGA subsystem and microcontroller application are presented together with corresponding source codes.
