Development Board for 32-bit Microcontroller Atmel AT91SAM9261
Demín, Martin ; Slaný, Karel (referee) ; Šimek, Václav (advisor)
Vestavený hardware je velice populární v této době. Proto jsme se rozhodli vytvořit desku s mikrokontrolérem AT91SAM9261 spolu so standartným a nestandartným hardwarem. Standartným, běžným by se dal nazvat port LAN alebo audio vstup-výstup. Nestandartným, špecialním by mohl být obvod FPGA firmy Xilinx o velikosti 200k. Toto dovoluje využít zažízení v oblastech, kde výpočetní síla obyčejnýho CPU již není dostačující.

Examples in environment ARMmbed
Maraczek, Patrik ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
The bachelor’s thesis contains basic information for working with microcontroller properly in ARMmbed integrated development environment. Thesis describe microcontroller, microchips, chip’s periphery, ARMmbed environment. Also manual is written for this environment. Four examples are solved at the end of thesis to explain how extended devices and sensors are working. Devices like 4-bit seven-segmented display, LED diodes, ultrasound sensor SRF02.

ARM Cortex M4 Development board
Volek, Lukáš ; Macho, Tomáš (referee) ; Burian, František (advisor)
In this work I aimed at designing a universal system for testing either STM32F407/417 by STMicroelectronics and later various sensors and communication buses. The result then is a main board with many specific connectors for individual buses even with connectors making all I/O pins accessible at the same time. Thanks to advanced switching regulators the power supply is capable of accepting a wide range of sources like single Li-Ion cell, pair of alkaline cells, 12V Lead battery, common wall power adapters (both DC and AC up to 15 Vpp ), USB, laboratory power supplies with multiple outputs and finally POE (Power Over Ethernet). Supply voltages are supervised by voltage comparators with an optical signalisation. (It is possible to determine the sick branch without a measuring instrument and blowing components in the most cases.) Another important parameter was a robustness of the supply and communication lines. There is a number of TVSs, chokes, and big and low ESR capacitors A PC software is intended for a basic functionality demonstration only.

Educational development boards
Ostřížek, Tomáš ; Fujcik, Lukáš (referee) ; Bohrn, Marek (advisor)
This paper deals with the design process of an FPGA-based development board for educational purposes, as a replacement of the obsolete Spartan-3 Starter Kit Board. Theoretical part describes the basic principles behind FPGAs and compatible digital and analog interfaces. The next chapter focuses on choosing optimal components for the board, mainly an optimal FPGA, in regard to course compatibility, implementation requirements and price. A complete circuit diagram is then designed based on the components as well as a printed circuit board layout. To simplify the process of configuration, a minimalistic Windows application using iMPACT batch commands is programmed. The last chapter describes the process of testing the development board prototype.

Universal Development Board for Pic18F Microcontroller Family
Jež, David ; Fučík, Otto (referee) ; Šimek, Václav (advisor)
My work describes design of the universal development board usefull with a various types of microcontrollers and the unified interfaces for the microcontroller's module board. It introduce the design and the interface and list of the Microchip PIC microcontrollers which can be used with development board. It also describes the features of the PIC18F4550 microcontroller and means about an different types of anothers manufactures. There is also describe of the design, creating the schemes of the boards, printed circuit boards and 3D visualization models in my work.

Car Air-Condition Control Unit with MCU HCS08GT60
Polóni, Pavol ; Straka, Martin (referee) ; Šimek, Václav (advisor)
The purpose of this project is to desing and produce development board, which is customized with respect to the deployment as an air-condition control unit in car. The following chapters of this work will gradually take its reader through the whole design flow of such embedded system. Literally speaking, selection of a proper MCU and set of external peripherals can be seen as the critical tasks. Particular attention will be also given to PCB (printed circuit board) manufacturing and components assembly. The core of the system is built around HCS08 MCU from Freescale and appropriate firmware written in C language.

Water quality analysis using colorimetry
Kovaldová, Eliška ; Zumberg, Inna (referee) ; Čmiel, Vratislav (advisor)
This bachelor's thesis deals with the analysis of water quality using colorimetry. Part of the work is an introduction to the physical and chemical parameters of water, as well as optical methods, which include photometry, spectrophotometry and colorimetry, and an introduction to regression analysis. These methods and analysis are followed by a practical part by measuring pH, nitrate and water hardness using a spectrophotometer and an AS7262 visible light sensor with a SparkFun development board. At the end of the work there is a comparison of absorption spectra, calibration curves and linear regression parameters of both methods.
