Microcontroller based system for body temperature sensing
Svoboda, Pavel ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
The dissertation is focused on creating a microcontroller system for measuring and recording temperature. In the opening part of the dissertation the requirements are described for the final product, selection of appropriate components and calculation of the suitable parameters of the specific components. In the following part the design of the circuit diagram and printed circuit board are described. The concluding part includes a description of the software equipment of the microcontroller and the program designed for the purpose of the transfer of data into a PC and the calibration of the equipment.

Level indikator with wireless communication
Smatana, Tomáš ; Friedl, Martin (referee) ; Szabó, Zoltán (advisor)
This thesis describes the design and realization of a device that is used for wireless measurement and control of liquid level. The first section explains the different options for level measurement, different implementation of wireless communication and describes the basic features of the Atmel AVR microcontrollers. Based on this analysis, appropriate solutions are selected sensors and wireless modules suitable for the design of the device. The second part is the design of a device which is subsequently implemented.

ALU Built-In Self Test
Bednář, Jaroslav ; Růžička, Richard (referee) ; Drábek, Vladimír (advisor)
This work deals with faults, errors and failures, which can occur during manufacturing and long term operation. Work describes the various failures and fault models. There are some approaches to get fault tolerant systems, mainly in hardware. The thesis continues with a summary of methods for ALU software testing. The last chapter is about tests generation for microcontroller MSP430.

Control of microcontroller via Internet
Kulig, Tomáš ; Fedra, Zbyněk (referee) ; Frýza, Tomáš (advisor)
The title of my bachelor’s thesis is Control of microcontroller via Internet. The result will be a web page (through this page it will be possible to communicate with a development board) and a design of development board itself. Due to complexity of TCP/IP protocol, I am going to use a simple operating system Nut/OS with the converter RTL8019AS (enabling transfer Ethernet to ISA bus) and with microcontroller ATmega128.

Digitally controlled triangle-, square- and harmonic wave generator
Bradáč, Lubomír ; Koton, Jaroslav (referee) ; Vrba, Kamil (advisor)
Feasible solutions of digitally controlled triangle-, square- and harmonic wave generators are described in this bachelor´s thesis. There is general description of wave generators at the beginning. We can divide the wave generators to two groups. The first group of them are Arbitrary Waveform Generators and the next group is presenting Arbitrary Function Generators which are working with Direct Digital Synthesis. There are descriptions of their features, possibility of using, advantages and disadvantages in bachelor´s thesis. Of consequence part there are plug-in cards which are used as functional generators and multifunction cards. Their principal characteristics are described in relevant chapter. The most important part of this bachelor´s thesis is suggestion of digitally controlled triangle-, square- and harmonic wave generator which make use microcontroller of company ATMEL. You can find the process of execution, description its features and controlling program in the last chapter. All of measured results are saved in compact disc which is part of bachelor´s thesis.

Smart accumulator tester and charger
Mílek, Čestmír ; Trmač, Jiří (referee) ; Michálek, Václav (advisor)
Nickel cadmium and nickel metal hydride accumulators sets are currently used for supplying hand tools (screwdrivers,...). Problems of cheap hand tools are chargers, mostly of it doesn’t use any charging driving circuits. In consequence of it the accumulators are kept incorrectly, which causes lowernig of lifetime. This thesis suggest circuit design Main of intelligent charging system, which enable better battery management, increases battery lifetime and lower load of environment.

SWR and HF power monitor
Gajdušek, Miroslav ; Blansko), (Metra (referee) ; Šebesta, Jiří (advisor)
This work deals with analysis methods continuous measuring systems for measurement standing wave ratio and high frequency power. Reflectometr, provision measuring standing wawe ratio, works in range frequence VHF (145 MHz, 443 MHz), for this width working frequence is used construction reflectometer with directive lead. Measurer HF power works into range 1kW. Further is in work go through problems communications bus for transmission data from unit monitor SWR a HF power into score modulus. With regard to high frequency interference is choice serial communication RS-485 , which is immune against disturbance. Further is designed evaluation unit MASTER, unit SLAVE and modules for measurement power and SWR. In finish is build up the firmware for units.

Automatic System for Load Characteristics of Power Supplies Measurement
Vojtek, Michal ; Dřínovský, Jiří (referee) ; Šebesta, Jiří (advisor)
The target of this work is create device, which will automatic measure values for find out loading characteristics of power supply with help of built-in electronic load. In case, that source of current supply will for example DC/DC convertor, measurement of input current and input voltage will be possible. Then there is no problem with determinate total efficiency of this power supply. Measuring system will be conected via serial interface of type USB with computer. It will be possible to save found out values with help of control program for nother processing. Control unit of whole system will be suitable microcontroller.

Control unit of four - legged robot based on microcontroller PIC
Youssef, Daniel ; Lamberský, Vojtěch (referee) ; Grepl, Robert (advisor)
This Bachelor thesis develops “Jaromir“, a four legged robot by adding appropriate sensors to it and designing a new control unit that is able to receive and process the acquired data by the sensors. The functionality of the control unit is tested by implementing a number of simple movements. This testing demonstrates the possibility of using this unit for the developing and testing of complex movement algorithms.
