Electronic RLC meter
Dvořák, Radim ; Hanák, Pavel (referee) ; Lattenberg, Ivo (advisor)
This work deals with measurement methods of passive components R, L ,C used almost in every electrical circuit. Work describes progress of choosing the right methods for measurement and also the process of designing the autonomous RLC meter with use of ATMEL microprocessor chips. The RLC meter will be powered from rechargable battery and will be able to measure primary attributes of RLC components.

USB cable tester
Fašanga, Jozef ; Hanák, Pavel (referee) ; Lattenberg, Ivo (advisor)
Measuring low resistances is a problem that also occurs with USB cables. The basic feature influencing the functionality is the voltage drop. The work deals with the theoretical possibilities of measuring low resistances and subsequent realization of connections. The ATmega32U4 microcontroller is used to control the device, which provides a USB interface for programming. Work theoretically discusses individual communications used for OLED display and ADC. Subsequently, the work discusses the design of the box for the device and the basics of the program, which is uploaded to the microcontroller.

Design of desktop applications using the workflow library
Zeman, Kryštof ; Číka, Petr (referee) ; Lattenberg, Ivo (advisor)
The theoretical part of the thesis generally focuses on history and development of work- flow library, briefly describing most important features and options, which gives the reader basics needed to understand and orientation in the topic. In practical part of the thesis is detailly analized prime example, which is showing options, flexibility and advantages of connecting WF and WPF libraries. Primarily the thesis uses the most widely used model and shows how to pass information between workflow and WPF.

Programmable timer configurable via USB
Dresler, Jan ; Číž, Radim (referee) ; Lattenberg, Ivo (advisor)
This thesis describes the design of printed circuit boards and programming AVR microcontroller, that communicates with the digital thermometer Dallas, also with photoresist circuit and RTC. Using sensors and relay allows switching of different devices. The switch allows direct configuration with computer via USB using the auxiliary circuit UART.

Receiving RTTY decoder
Šuňal, Štefan ; Caha, Tomáš (referee) ; Lattenberg, Ivo (advisor)
This thesis deals with designing and implementing autonomous decoder for RTTY communication. Theoretical part of the thesis deals with researching the RTTY technology and FSK modulation, which it uses, focusing mainly on the methods of demodulation. Next part of the thesis compares suitability of available platforms. Practical part of the thesis describes the design and implementation of circuit board, firmware and computer application. The device is using STM32 microcontroller. Firmware was developed in C++ using Arduino. The computer application was created by using C\# and WPF. 3 methods of FSK demodulations were implmented. One is using a FFT algorithm. Other two calculate frequency based on the period of square signal.

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.

USB controlled voltage and current source
Pytela, Ondřej ; Kubánek, David (referee) ; Lattenberg, Ivo (advisor)
This diploma thesis is focused on complete construction of lab source which is controlled and powered by USB in personal computer. Different types of possible solutions are mentioned and finally one of them has been picked up as a best choice, which is developed in the rest of this thesis. Besides hardware construction there is also shown creation of main program for PIC18F14K50 microcontroller and main application that provides controlling of USB source via personal computer.
