Narrowband PLC communication for Smart Metering
Kubů, Jiří ; Blažek, Petr (referee) ; Mlýnek, Petr (advisor)
This bachelor project is about narrowband PLC communications. The work describes the basic principle, division of PLC communication, history, technology, utilized communication standards and interference affecting the data communication technology. In this work we also performed experimental measurements in real environments with modems from Texas Instruments C2000 and C2000 TMDSPLCKITV4 PLC PLC TMDSPLCKIT-V3. The results of the measurements are real transmission rate. Moreover application was created for remote data collection along with PLC modems C2000 PLC TMDSPLCKIT-V3, the aime was to edit PLC modem firmware and create applications for receiving data from the terminal.

Controlling of programmable analogue circuit
Sobotka, Josef ; Hanák, Pavel (referee) ; Vrba, Kamil (advisor)
This work deals with the design of the control software for the programmable analog circuit adjustable by means of a computer via the serial interface for the computer, as well as for programming the microcontroller. In addition, analyses the internal structure of programmable analog circuit on which it is proposed to further control, design of printed circuit boards for final programming and test equipment and measurement of the basic parameters of the circuit (transmission and phase frequency characteristics of parts and units).

Audiostimulation
Sobotková, Marika ; Walek, Petr (referee) ; Sekora, Jiří (advisor)
The aim of this bachelor thesis is to design a device for audio stimulation, which will be used during examination with functional magnetic resonance. The next aim is to familiarize readers with magnetic resonance and stimulation. Whole device is controlled by microcontroller from open-source platform Arduino, model Due. Hardware is based on a non-soldering contact field. There is also draft of printed circuit board. Software is represented by flowcharts. Algorithm is designed and realized in wiring Arduino's library (which belongs to Arduino). Microcontroller is controlled by graphical user interface made by MATLAB.

Generic BIOS Update Mechanism for Linux
Mariščák, Igor ; Šimek, Václav (referee) ; Kašpárek, Tomáš (advisor)
This work provides overview of creating of a simple driver for the BIOS flash memory by accessing the physical computer memory. Although, the BIOS is one of a system's core components, there is no standardized update mechanism approach. Purpose of thesis is to create module driver by taking advantage of existing interface subsystem MTD, to suggest and implement driver for one specific device to Linux kernel operating system. Also explains technique allowing write access to registers of the flash memory with utilization of configuration file.

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.

Module for remote access via Ethernet
Pospíšil, Martin ; Šrámek, Petr (referee) ; Prokeš, Aleš (advisor)
This thesis is about creation of control software (firmware) for remote access unit, using ethernet for communication. It implements web interface for control and monitoring of connected device, which requires both digital and analog signals for control. Hardware is based on C8051F120 as main microcontroller and CP2200 as ethernet controller. Thesis briefly describes most important protocols used in this system and examines features of the Silicon Laboratories TCP/IP stack.
