Laboratory assignment for ARM Cortex-M3 microcontroller
Libicher, Radek ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This bachelor’s thesis contains expansion circuits and three laboratory assignments for MBED NXP LPC1768 development kit. The document is divided into three parts. The first part deals with the description of the ARM microprocessor, development board and development tools. In the second part, six expansion circuits were designed. These circuits have been used to create Peripheral Board in the form of one-sided PCB. Using this board, you can easily develop applications. A set of C++ libraries was created for easy and efficient operation. The last part is dedicated to three laboratory assignments – Digital Clock Using Real-time Clock, Input Voltage Measurement with the AD Converter, Digital Thermometer with a History of Measured Data. Detailed descriptions of the solutions for each of these assignments were created, including the flowchart. These assignments are conceived for the reasons of microprocessor technology teaching at the faculties of electrical engineering.

Realization of the control device for a temperature chamber
Obšil, Martin ; Levek, Vladimír (referee) ; Čožík, Ondřej (advisor)
The bachelor‘s thesis deals with the realization of the temperature chambre control. In first part there are definitions of different types of the power regulation. In the second part of this work are approached an infrared ceramic heaters and a heat transfer by radiation. The third section is about realization this device. There are explanations of realization of each part. The whole circuit is controlled by a microprocessor which also controls the power section with triac which regulates power on the infrared ceramic heater. The next part deals with a design of the printed circuit boards. In the fifth section is desctription of the software and in conclusion there are demonstrated results of the work.

Robot Trilobot Control Using FITKit
Růžek, Michal ; Novotný, Tomáš (referee) ; Orság, Filip (advisor)
The goal of this master's thesis is to design a robot Trilobot controller using a FITkit platform. It describes sensors and actuators widely used in mobile robotics. Part of the thesis is aimed to analyze in detail current Trilobot's peripherals, their conections and ways of communication. A circuit diagram of designed electronics is completed by the PCB design and description of small changes of the current Trilobot. The thesis also contains implementation of utility HW in the FPGA and a software library for a microcontroller. The finished control unit is tested by sort of demonstration applications.

Digital conversion of analog signals
Čermák, Petr ; Sedláček, Jiří (referee) ; Murina, Milan (advisor)
My work is focused on digital elaboration of the analog signal. In my work the analysis has been carried out in all parts of digit chains processing analog signal. The entranced variable is signal from measuring coil, which is afterwards strengthen and transfer to a sampler. The sample signal is processed by an A/D converter and then sends to a parallel port. On the basis of acquired data the scheme has been constructed for sample processing. The transfer to the parallel port is done (made) in two steps, at first one part of the word is transferred and then the rest of the word follows. Between the converter and sampler is tight relationship and synchronization. Both of them are managed from one central bus.

The heartbeat counter
Malínský, Zdeněk ; Dlouhý, Jiří (referee) ; Švrček, Martin (advisor)
Heart rate variability belongs to basic and most frequently interpretation of physiologic statement in medicine. The pulse rate serves as an indicator of the heart activity. The subject of this diploma thesis is projection of the heartbeat counter. The work describes electrocardiograph and separated waves, ways of calculation heart rate, characteristics mechanism for measuring and other necessary information about heart rate measuring. This master thesis fixates on heart rate-calculation from including R-R intervals. Here is described whole project of heartbeat counter, properties of separated blocks and calculation of useful parameters. Further there is noted software resolution for the microcontroller and program for the calculation of heart rate frequency including unwinding signal preprocessing and detection of separated QRS complexes. The products of this diploma thesis are the circuit including the board circuit and codes of separated programs.

General purpose analog signal converter
Strážnický, Martin ; Povalač, Aleš (referee) ; Kubíček, Michal (advisor)
This work deals with the design of a galvanically isolated converter of continuous analog signals and the design of a galvanically separated converter of digital TTL signals to HTL signals. The device is complemented by a STM32 microprocessor, which ensures the connection of analog input and output. The result of the work is the circuit structure of individual units, the results of simulations of important units, complete data for the production of device and measured values of individual units.
