Family Independent Microcontroller Programming Library
Konečný, Ondřej ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This project describes a concept of a library architecture that will enable to hide platform-specific behaviour of different MCUs under an united API that will enable the developers to develop portable applications. After a short summary of the current situation, the report describes the main principles of the library-to-be followed by definitions of behaviour of each module that can be controlled using the library. Then this report describes techniques used in the implementation and platform specifics. In the conclusion there is an idea of the direction in which the development could continue.

Digital Oscilloscope on FITkit Platform
Veškrna, Ondřej ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
This thesis deals with the design of a device that enables to monitor the behavior of the measured signal on the computer screen, using the principle of the digital oscilloscope. The control element of the device is the field programmable gate array (FPGA) on FITkit platform. The FPGA configuration controls the input signal sampling and sends the received samples through the USB interface to the PC. The graphical application implemented in the computer tries to restore the signal and then displays it on the screen.

Temperature Monitoring
Kotačka, Aleš ; Winter, Jan (referee) ; Kubek, Ján (advisor)
This master's thesis deals use FITkit for longtime temperature monitoring without necessity connection on PC. Describe possibilities connection different heat-sensitive elements to FITkit inclusive physical realization. Further this thesis deals with measuring of temperature, displaying temperature and saving to memory, blocks-partitioning of memory. Is defined communication protocol between FITkit and PC for bulk downloading of data. So are solving problems with saving measure data to text files and next processing in table processors.

Firmware for Multi-Unit Wireless Sports Timekeeping Device
Gál, David ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This paper describes the design and subsequent implementation of software for multi-unit wireless sports timekeeping device. Used hardware is based on a different thesis and is composed of a control, the primary unit, and end, secondary, units. Both types are equipped with 16-bit PIC24F microcontrollers and wireless communication is catered by RF modules broadcasting in the 868MHz band. The design is aimed primarily at wireless use of secondary units to measure time and to eliminate measurement errors associated with wireless transmission. It also deals with reducing the consumption of units and the use SD cards to store the measured times. Implementation is done in C.

RF power meter
Hlaváč, Štěpán ; Jedlička,, Petr (referee) ; Drexler, Petr (advisor)
This master’s thesis describes various principles of measurement of electromagnetic waves in a free space and on a line. Used sensors and their real parameters are given for every method. The analysis of protections of high-frequency inputs of measuring instruments is done here and the most suitable method and protections of input for realization are chosen. The analysis of design of secondary protection of high-frequency input is done in this project. The protection of input is realized and measured. The suitable method of measurement is chosen as well as the sensor for measurement of power. The block diagram and circuit diagram of the meter of power are designed. According to designed conception the measuring instrument for measurement of power is realized and its single qualities are measured during the realization. In the final part its precision is measured and the evaluation of results is done.

Design of Flow, Temperature and Pressure Measuring System
Macíček, Ondřej ; Čížek, Martin (referee) ; Sekora, Jiří (advisor)
This master’s thesis contains complete design of the complex measuring system for temperature, pressure and flow. Objects of measuring are pressure in rabbit’s heart ventricle, flow of the saline through the heart and the temperatures of physiological solution. Work is interested in programming of microcontroller and program for LabVIEW environment, which is used to view and export relevant data related to measuring. Text also contains technical documentation of functional sample of measuring system.

DDS Based High-frequency circuit analyzer
Priškin, Jiří ; Brno), Tomáš Mádr (DCOM (referee) ; Šebesta, Jiří (advisor)
At first this thesis is dealing with the basic principles of network analyzers and afterwards goes to propose conception of a polyscope, as a special type of the scalar network analyzer, designed for magnitude frequency response measurement of two-port devices. As a result of this part of the thesis is the polyscope's block circuit diagram and also selection of key integrated circuits for sweep generator, logarithmic detector and control circuits. As the following part of the thesis is a design of the all basic analyzer's circuits resulting in their schematics diagrams and printed circuit boards, do assembly of all modules and mechanical construction of the instrument and look of the front panel. Some of the tasks is implementation of the firmware and personal computer application able to download measured data from the circuit analyzer via USB and generate chart in Microsoft Office Excel book.

Design of evaluation network for in-vehicle networking communication chips
Kupčík, Ondřej ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
Cílem této diplomové práce bylo navrhnout moduly určené k demonstraci a testování některých obvodů, používaných v automobilové technice. Jedná se o LIN transceiver NCV7420 a osmivýstupový výkonový budič AMIS-39101. Návrh spočíval ve vybrání a popisu parametrů vhodných podpůrných obvodů, vytvoření celkového schématu a navržení desky plošných spojů tohoto modulu s ohledem na kompaktní rozměry a předpokládané testy. Dalším krokem byla tvorba firmware řídicího mikrokontroléru (C8051F344), jež zajišťuje LIN komunikaci, řízení budiče a základní monitorovací funkce. Poslední část popisuje software pro hostitelský PC umožňující komfortní řízení sítě složené z těchto modulů. Pro úplnost byl tento projekt doplněn o přehled vlastností sběrnice LIN a metodiky testování LIN transceiveru z hlediska funkčních parametrů i některých EMC měření. V příloha obsahuje kompletní schéma modulu, výkresy desek plošných spojů, seznam řídicích příkazů a fotografie modulu.
