Harness tester
Smola, Tomáš ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
This thesis deals with issue and construction of wire harness tester. In the first place, is this thesis focused on market exploration and comparison of comercial testers with concrete requirements for small batch production. I will try to find a suitable product in worldwide market, which would be convenient for company producing construction machinery. For testing switchboard harness we need to test interconnections between connectors, resistors, relays, diodes, transils and switches in the dashboard. If I can not find some product, I will try to design some new tester. My priorities will be testing all components in harness, maximum flexibility of tester for the future trends in contruction of rollers and user friendly control.

Wireless Security and Surveillance System
Výborný, Jiří ; Frýza, Tomáš (referee) ; Prokopec, Jan (advisor)
This Master’s thesis deals with design and construction of a wireless security and surveillance system in ZigBee wireless networks (IEEE802.15.4). The design consists of creating a star network topology with intended monitoring of home area via end device boards paired with coordinator board, which provides basic networking functionality. End device is used to send data from a temperature sensor DS1631 and magnetic reed switches to coordinator. ZigBee module ZDM-A1281-A2 made by MeshNetics company embedded on each board contains a micro controller ATMega1281 and a transceiver AT86RF230 working in a 2,4GHz frequency band. System is able to notice of any door or window move actions and too high temperature. The non-fully functional ZigBee stack, which is called an Open MAC software, based on MAC (Media Access Control ) layer and PHY (Physical) layer from MeshNetics, has been used to develop the user software. Open MAC consists of three application samples in C code. One of them was modified by the user for an application of communication between the module and sensors. The same design with module RC2204AT made by Radiocrafts company was tested as well, but it couldn’t be executed. All developed boards have been constructed and tested via Terminal PC program.

Cyklocomputer with Frequency Meter
Netáhlo, Tomáš ; Fedra, Zbyněk (referee) ; Hermany, Jiří (advisor)
The Bachelor’s thesis deals with design and realization of the cyklocomputer with a measuring frequency of pedaling. The device measures speed, pedaling frequency, heart rate, distance traveled and the current time and date. Measured values are stored in memory and then can be transferred via USB bus to computer. The work includes a description of the magnetic sensors and ECG sensors. The practical part includes the design of hardware and software cyklocomputer.

Control and Diagnostic System for I2C Bus
Juhás, Miloš ; Šebesta, Jiří (referee) ; Urbanec, Tomáš (advisor)
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.

The peripheral testing module design for mobile robot.
Mašek, Petr ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
This diploma thesis deals with design and realization of testing modules for detecting a defective peripheral in a mobile robot. One of the modules is intended for the diagnosis of ultra sonic range finder. The second one simulates the behaviour of these ultra sonic range finders, making it able to determine interface on which it is necessary to look for an error.

I2C-RS232 converter
Bednařík, Martin ; Zezula, Radek (referee) ; Zeman, Václav (advisor)
The objective of this thesis is to get familiar with function of I2C bus and microcontrollers AVR and study the principle of connecting microcontroller with the other circuits via this bus. Another goal is to design a device which will enable a communication between personal computer and controlled circuits. A part of this project is production of necessary microcontroller software equipment and to develop own communication protocol. Another output of this project is getting an overview of applied technologies, study possibili-ties of their additional usage and potential enlargement of device with another components.

Communication with external devices by I2C bus
Prax, Jakub ; Šebesta, Jiří (referee) ; Frýza, Tomáš (advisor)
This diploma paper deals with the data bus line I2C and a supportive demonstration tool for the subject Microprocessor technology taught at the Radioelectronics faculty. The data bus line I2C is convenient when short-distance data transmission with restricted spatial possibilities is required but high velocity of data transmission is not necessary. The tool is compiled in such a way that enables it to also perform other tasks apart from those dealing with the I2C data bus line. The data bus line in the tool is utilized for transmission of date, time, temperature, data for the D/A converter, data from and to the EEPROM memory and data to 16 bits expander.

Teaching guide for the ATMEL development board
Navrátil, Petr ; Hadinec, Michal (referee) ; Friedl, Martin (advisor)
Bachelor’s thesis is focused on developing applications for the developing board with microcontroller ATMEL (ATmega16). Bachelor’s thesis describes the microcontroller including a description of hardware components and control registers. This book describes the various peripherals on the developing kit with programming examples. Simple modules have been created for the developing board, which could be used to program complex project and easy aplications. On these modules are periphery as matrix keyboard, encoder, real time clock and circuit L293D for controling DC motor with PWM signal. The AVR Studio version 4.18 is described and used here as a programming software. This work should serve as a guide about ATMEL AVR ATmega series for beginning or advanced programmers. Examples of individual programs are a part of this work.
