Microcontroler based ECG Generator
Bureš, Michal ; Bubník, Karel (referee) ; Sekora, Jiří (advisor)
This thesis deals with the generation of an ECG signal and options how to generate a physiological or a pathological signal using the microprocessor. On the basis of the studied methods for generating signal was used the graphic method, using the table values to describe the an individual waves contained in the ECG signal. Bacherol’s thesis solves a design of the individual parts that are needed to realization the genererator. These parts are a block diagram, a system design and a flowchart. On the basis of a design is constructed and programmed function ECG signal generator.

Meteorological Station with Remote Access
Svoboda, Josef ; Číž, Radim (referee) ; Sysel, Petr (advisor)
This thesis discusses design and realization of air temperature, pressure and relative humidity measuring device, transmission of measured data over internet and their presentation on a web site. First chapter introduces reader into principles of measuring air temperature, pressure and relative humidity and various types of sensors used for measuring . Next, the conception of designed system is described. Designed system must accomplish tasks from reading raw data from the sensor up to thein graphical presentation to the internet user. Second and third chapter describes hardware and software design of air temperature, pressure and relative humidity measuring unit. In next part one can find description of software used to transmit measured data over internet and software for generating web pages which are shown to users. The work is revieved in the final part of this thesis.

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.

Audio amplifier controlled by the IP protocol
Dvořák, Petr ; Schimmel, Jiří (referee) ; Kouřil, Jiří (advisor)
The bachelor thesis is intent on projection and realization of a device whitch is capable of communicate with a remote client through the Ethernet making use of the protocol set TCP/IP. This communication will be used for the control of analog and digital outputs of the device, which is able to be attached to any amplifier of audio signals. One of used protocols is UDP. This protocol is closely described, because it is used for transfer of data controlling outputs. The whole device is controlled by microprocessor ATmega32, which operates the communication with the ethernet interface through the controller ENC28j60, the communication with the D/A converters MCP4922 and controlling of digital outputs and a display. The device has its own IP and MAC address for identification in the network. It is possible to edit both addresses in the menu of the device with the help of the module LCD, the display of 2x16 characters with fours buttons. The audio amplifier staffed by the voltage controlled by the computing amplifiers SSM2018T is connected to this device. The amplifier is proposed as six-channel with symmetric inputs through the connectors XLR and unsymmetric outputs through the connectors CINCH. The operating programme which is able to be run on PC with the operating system Windows is necessary for the remote control of the device in the network and all functions of the device are controlled by this programme. This programme enables to control the device after setting the IP address of the destination device and the communication establishment. The motherboard is proposed as a universal module which keeps at disposal up to 6 analog outputs with the range of the control voltage 0 – 5 V and up to 21 binary inputs/outputs.

Control of ball and plate system
Bednář, Ladislav ; Bartík, Ondřej (referee) ; Veselý, Libor (advisor)
The goal of this work is to design a control algorithm for position controlling of the ball on 2D plate with feedback implemented by camera. Frist part is devoted to the design of steper motor controller, that is controlled by analog inputs. Controller was tuned on CompactRIO platform later replaced with microprocessor by Freescale. PCB design for microprocessor board is included. Next we described controlled system by mathematical model, which we use for PID controller design. Mathematical model is designed in linear form and nonlinear form, which analyze nonlinearity of rolling friction. Image processing with control loop is contained in Matlab-Simulink workspace. At last, laboratory task is designed.

Profiler for Generic Simulators of Microprocessors
Wilczák, Milan ; Přikryl, Zdeněk (referee) ; Masařík, Karel (advisor)
This thesis presents design and implementation of profiling tool for newly created microprocessors. For microprocessor description specialized language ISAC is used which describes processor resources, instruction set and behavior. Final profiler is an extension to existing simulator and can be used for optimizing of both processor and its applications. Principle of the profiler is generating events by simulator and processing these events into statistics.
