LED 3D object controlled by microcontroller
Gasper, Michal ; Němec, Zdeněk (referee) ; Holoubek, Tomáš (advisor)
The aim of this work is to design and produce a LED 3D object controlled by a microcontroller. The research part deals with the topic of microcontrollers, their history, architecture and components. Furthermore, this section describes the selection of a microcontroller and the resulting device for this work. In the practical part, the own design and solution is discussed in detail. Subsequently, the procedure for producing and writing the program code for controlling the LED 3D object is described. The program is written in C++ using the Arduino IDE and the FastLED library. The result of the work is a functional product that fulfills the assignment.

DMX 512 protocol analyzer for personal computer
Vahalík, Jiří ; Sysel, Petr (referee) ; Krajsa, Ondřej (advisor)
The bachelor thesis deals with the design of a DMX converter for a personal computer. The theoretical part summarizes the DMX, RDM and Art-Net protocols and other commonly used communication protocols used by microcontrollers. In the practical part, a device circuit is fabricated, which is subsequently processed as a printed circuit board. In the last part of the thesis, programs are designed to ensure the functionality of the whole converter.

Control System of Small Mobile Robot
Rysnar, Jiří ; Florián, Tomáš (referee) ; Žalud, Luděk (advisor)
This master’s thesis elaborates on the control of a wheeled mobile robot and its sensor system. The sensors provide information about distances of obstacles in its surroundings and orientation in area. The communication is realized by radiomodems, commands and data are sent by serial link between microncontroller and the PC.

Measuring station firmware for wireless data collection via LoRaWAN
Jánoš, Vít ; Možný, Radek (referee) ; Juráň, Radovan (advisor)
This thesis deals with software development for STM32WL55-JC1 MCU. Development kit was chosen primarily bacause of its LPWAN possibilities. Final prototype communicates on LoRaWAN network. Data are sent through public network from The Things Network, these data are concentrations of carbon dioxide, temperatures and carbon dioxide flux. Data are also backed up locally on SD card along with timestamp. The software was designed with the use of the chamber measurement method in mind, which is also described in the text.

Robotic Manipulator Controlling Using Microcontroller
Zemánek, Martin ; Škarvada, Jaroslav (referee) ; Růžička, Richard (advisor)
This master's thesis deals with control robotic manipulator ROB 1-3 using common joystick and microcontroller HC08 NITRON or HC08 LJ12. The goal of this work was creation of module for controlling axes position of servos included in robot by analog signal coming from connected joystick. There are formed possible suggestions about connecting individual parts together for both autonomous and version using development kit. Programming code suggestion is based on these connections during further development. The limitations of using it are described in analysis and final results are shown in statistics results.

Electronic control of servomechanism for drive-simulator
Valouch, Martin ; Šebesta, Jiří (referee) ; Fedra, Zbyněk (advisor)
The aim of this bachelor´s thesis was construct electronic driving unit of positioning servomechanism in driving simulator. As controlling unit was chosen 8-bit microcontroller ATmega16 produced by ATMEL® and for scan actual angle of displacement the seat magnetic rotation encoder AS5040 produced by Austriamicrosystems®. For construction of bridge circuit were chosen MOS transistors. This transistors are excited by two Power MOSFET Drivers. Their job is convert output signal TTL logic from microcontroller to voltage in needed norm for transistors circuit closing. Data from PC in drive simulator can be transfer by serial interface RS485 or RS232.

Hardware Accelerating of Encryption Algorithm
Hradil, David ; Martínek, Tomáš (referee) ; Kořenek, Jan (advisor)
The goal of this thesis is to design a hardware realization of circuit which will implement the AES algorithm. A motivation was to make an acceleration against the classic software encryption. The acceleration is achieved by special designed parts of the circuit, which correspond to particular operations of the AES algorithm. First, there was necessary to design the circuit. In the next step there was a need to describe the designed circuit by the VHDL language. Then the circuit was simulated and synthesized. Due to comparing the circuit with software processing a software implementation was created. Both implementations were created for the FITKit platform. The hardware implementation is made by the FPGA technology and the software implementation is realized in a microcontroller. The result of the thesis is almost one thousandfold acceleration against the classic software encryption.

Control system for equipment using renewable energy sources
Novotný, Jan ; Bradáč, Zdeněk (referee) ; Benešl, Tomáš (advisor)
The work deals with design of power and control electronics for water micro source in island network. In the general part the readers are acquaints with the issue of renewable energy sources and describes commercially produced micro sources. The practical part deals with the design of its own control system and power electronics using its own control system or PLC for water micro source. The microcontrollers were used for the implementation of the control system, for which the program part was created.
