The objective of this diploma thesis is design and realization of I2C bus analyzer. I2C bus protocol is briefly described, together with means of connecting devices to the bus. Next the basic requirements for I2C bus analyzer are defined. Then the design of hardware I2C-to-USB converter including block description is proposed. The chapter dedicated to converter firmware describes method of communication with PC, decoding of intercepted commands and principles of master, slave and passive mode of bus monitoring. The last part is focused on operation software and its structure. Described are individual interfaces, most notable classes and default plugin modules.

My master thesis is focused on intorducing, analysing and describing the microprocessor controlled charger. The thesis is firstly describing and analysing the topic of accumulator cell charging for common technologies. Than there is detailed description of specific accumulator cell types (NiMH, NiCd and Li-ion) which is the microprocessor controled charger intend for. The next part of this thesis is showing the proposal of the charger. There is the block diagram, charger detailed schematics based on this block diagram. There is also list of the possible useful componets neccessary for charger assembling. All this is used for the final proposal of the chager itself. The main scope of this thesis is than the charger's microcontroler firmware decribed at the end of this thesis. Finaly confirmation of the charger proper proposal and assembly is the battery charging with the given basic parameters.

The aim of this thesis is design and realization of automatic test bench for parameters analysis of airborn radio-communication system R-863. Firstly we have taken up principles of the analysis properties of the radio system R-863. Then we proposed test bench for parameters analysis. In the next step we realize and integrate the digital control panel into the test bench. In harmony with the previous steps we have made program and software for the automatic test bench. Finally we make the user manual, which is easy to use.

This thesis describes the design of construction of the converter USB joystick on the Ethernet interface. In the first part are theoretically analyzed both protocols used for the converter. An analysis of current microprocessor trade and their possible using for application in this project. Next part including the specification of used microprocessor and all options of programming and debugging of the microprocessor. Another part deals with the detailed design of the hardware interface. The last part describes the software equipment of microprocessor and the final appreaciation of work.

The object of this work is to meet readers with the basic principle and solution of high order digital modulator with integrated circuit AD9957 produced by the company Analog Devices. Block diagram and final scheme of the modulator and device construction is presented. Standard USB interface for communication, control and data transmission between modulator and host represented by personal computer is applied. The project describes following parts of the designed system: PCB layout, control firmware of MCU and application program running under PC. In the conclusion, chosen results of measurement are described and evaluated.

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.

This project is dealing with a design of device for measuring and displaying of sports results. The project is divided into three parts - the design of control board for LED display, next the control unit and finally the remote control. LED display contains LED segments and graphical line for the text. The control unit and remote control are communicating with LED display, measuring devices or with a PC. It is possible to operate the whole system by tablet or a smartphone. There is a software made for all processors of all parts, which can demonstrate the function of the system and all added peripherals.

The thesis deals with design and construction of diagnostic device for batteries. In the analysis I described and compared well known I2C bus and quite similar SMBus. The latter bus is used in the laptop batteries called Smart Battery. The design includes the USB bus, which I described briefly in analysis too. I suggested a several designs, discuss them and build the best one of them. The realization of the diagnostic device includes construction aspect and programing aspect. Both aspects are described in the thesis. At last, the results of test diagnostic of several batteries carried out by designed device are introduced.

This master's thesis is primarily focused on the design of an electronic access control system using the BodyCom technology. The first section describes the working principle of this technology and its influence on human body. The second section shows an application of this technology in construction options of the electronic access control system.

The objective of this thesis is design of the universal USB measuring module for virtual instrumentation. The module is connected to PC via USB interface. The module have analog inputs and analog outputs. The inputs have some switchable ranges, adjustable high-pass and low-pass fiters. Also the module have the digital input-output unit with 8 channels with configurable data direction and voltage level. Physical layer for digital serial interfaces SPI/UART and I2C is also part of this unit. The module is able to communicate with LabVIEW enviroment. The teoretical part contains survey of the commercial USB modules for data acquisition and generation from various manufacturers with its basic parameters. Some selected modules are described in detail. Furthermore the thesis deals with possibilities of connecting the USB module with the LabVIEW enviroment. The practical part deals with the design of input-output circuits and with design of the module itself. Furthemore, tho communication protocol, utility library and demonstration LabVIEW software are described in this part. At the end of this part, there are results of verification measurements. The result of this thesis is completed universal USB measuring module with utility library and demonstration program.
