Communication assembly for optical cableless linking
Kapuš, Martin ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
This Graduate Thesis is about communication module for optical wireless network. This device read data from RS232 port and two analog inputs and sends it through internet to a remote Computer. Furthermore allows voice communication between local user on module and user on remote computer. Device allows communication with standard headphones and microphone, or with Bluetooth handsfree. Basic part is microprocessor MCF5223 and Bluetooth Ezurio BISM II module. Control program has been written in C language. Printed circuit is created by EAGLE program. This device is managed via web interface and settings have been stored into EEPROM memory. Work contains description of separately parts and blocks, source code of program, description of source code and printed circuit designs.

Educational board for STM processors
Očenášek, Matěj ; Novák, Lukáš (referee) ; Šteffan, Pavel (advisor)
This work deals with design of educational board for STM32 microcontrollers. This educational board contains basic types of peripherals such as OLED display, EEPROM, LED or seven segment displays. The theoretical part focuses on the description of the STM32F303 processor and the Nucleo-64 development board on which the processor is installed. It describes in particular its properties. In the theoretical part, besides the STM32F303 processor, the individual parts of the educational board are described. The practical part deals with the design of the block diagram, the scheme and the design of the printed circuit board.

ECG generator for equipment testing
Čech, Petr ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
This diploma thesis is focused on testing ECG monitors and ECG instruments. There are discussed origin and charakteristics of ECG signal. The ECG signal is presented by standard leads. This is the reason, why the way of making leads is mentioned. One chapter is aimed at generating ECG signal. There are set requierements for the ECG generator. These requierements results from ECG instrument possibilities and from ECG signal character. Next part of this diploma thesis includes hardware design of each part of the system. The system was designed with respect to mobility and 12-leads systems compatibility. Finaly the thesis includes design of the controll software.

Ultrasonic distance measurement
Klich, Michal ; Krajsa, Ondřej (referee) ; Lattenberg, Ivo (advisor)
The aim of this bachelor thesis is the design and manufacture of a controlling program of equipment for distance measurement using ultrasonic sensors. It focuses on a detailed description of the whole design from the basic properties of the components to the creation of schemes and PCB design. It subsequently describes in detail the development of controlling software of the equipment. The work briefly describes the most important parts of the code. It summarizes all theoretical and practical knowledge gained during the creation of the whole design, it explains the principles of the functions and works of individual parts and it suggests the best possible options of connection of the whole equipment. It also suggests the best possible variants of the entire circuit. The bachelor thesis also describes the microprocesor AVR ATmega8 from the Atmel Corporaton, which controls the entire device, as well as EEPROM memory chip 24LCXXX, SRF05 ultrasonic sensor and communication with the PC via USB using a microchip FT230XS-R.

Radio Telemetry for RC Aircrafts
Žák, Tomáš ; Fuchs,, Michal (referee) ; Povalač, Aleš (advisor)
Master‘s thesis is focused on problematic about state of RC plane model during the flight. Device is able to measure overload, height, position, pressure and velocity of the flight and store this measurement data to memory medium. The main aim of the master‘s thesis was to design a functional board, firmware for device and design simple program for evaluating of measured data. Involvement consists of five basic parts. First part is microcontroller, which processes measurement data and communicate with others parts. Next is accelerometer. Accelerometer is used for scanning overload of the plane. Barometer is used for measurement of height and pressure. For measuring position and velocity is used GPS module. Last part is memory medium. MicroSD is used as memory medium for storing measurement data. Evaluation of measured data is realized as simple program with base graphical user interface. Program was created in Matlab.

Environment control with microcontroller
Králíček, Martin ; Šebesta, Jiří (referee) ; Fedra, Zbyněk (advisor)
This bachelor project focuses on equipment for environment management and check with help of microcontroller. This equipment should enable us to check and manage home environment for example for goldfish, hamsters, spiders and other small pets. Further on, this project describes individual parts of equipment which the ECM-01 consists of. ECM-01 is consists of general block, feed block, relay block with power supply and sensors. The ECM-01 consists of several functional blocks which are controlled by the main microcontroller. The functional blocks contain measurement transducers and action units. The choice of blocks depends both on individual environment and the user. The user can choose which values he needs to control and measure.
