Emulation of Character-Based LCD Display Using E-Ink Technology
Rusín, Tomáš ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The aim of this bachelor thesis is to design a simple printed circuit board interconnect. The board is planned to be equipped with a microcontroller that will receive communication signals originally intended for LCD character displays. The communication may be parallel or serial, in the form of SPI and I2C type interfaces. These signals are planned to be received and converted to E-Ink display signals. That display will show information in the same format as it was designed for LCD displays. The E-Ink display replaces LCD displays without the need of changing the original library or the original communication interface. This method of replacement is suitable when a LCD character display is destroyed and a suitable replacement cannot be found, or when the E-Ink display is more suitable.

Binary masks DLP with DMD chip
Filip, Jakub ; Dostál, Zbyněk (referee) ; Matoušek, Radomil (advisor)
The diploma thesis aims to create a library in the Python programming language, which can control the DLP LightCrafter 9000 EVM evaluation module. Through this library, the potential of the purchased module in the field of high-speed imaging of binary masks should be achieved. The theoretical part of the thesis deals with DLP technology and hardware. The hardware properties are specified in more detail with respect to the purchased module. The following chapters focus on the command control interface and the GUI application, which provide additional information not only about the method of communication between the module and the PC but also about the conditions for achieving the desired outputs. The practical part deals with the analysis of communication between the module and the PC, the processing of digital image data, and the implementation of the library in the Python programming language.

Monitoring the living environment in the house
Dlugoš, Daniel ; Ježek, Michal (referee) ; Staněk, Kamil (advisor)
This work, tries to create a small, rechargeable and portable device that senses temperature, humidity, barometric pressure, dust particles, carbon dioxide and VOC concentration. The air quality monitor can reliably measure the physical quantities encountered in every indoor environment, evaluate them and display them to the user. The sensors, data storage module and OLED display are housed on a custom-made PCB board.

Automatical plant growing
Stupka, Tomáš ; Dřínovský, Jiří (referee) ; Götthans, Jakub (advisor)
The aim of the thesis is to design and an automated hydroponic station, which will be intended for the cultivation of herbs and vegetables for the purpose of user. The station will be controlled by a Raspberry Pi minicomputer, to which a number of sensors will be connected, which will check pH, EC, ambient temperature and other quantities. Furthermore, an external sensor with an ATMEGA328P control processor will be designed to check the ambient lighting parameters. A web interface will be created for the station, which will allow the user to follow the development of individual measured quantities over time.

I2C Bus to RS232 Bus Convertor
Votava, Martin ; Marvan, Aleš (referee) ; Orság, Filip (advisor)
The main goal of this Bachelor's thesis is to create I2C bus to RS232 bus convertor. Using I2C bus the convertor drives 8bit I/O expander. In theoretical part buses I2C and RS232 are described along with PCF8574. There is also mentioned selection appropriate microcontroler and design of comunication protocol. Practical part is dedicated to creating control program for microcontroler, appropriate comunication protocol processing and convertor testing. There are also described some auxiliary products and program testing.

Design and realization of a developement board for BeagleBoard
Ťapucha, Andrej ; Hanák, Pavel (referee) ; Krajsa, Ondřej (advisor)
Contents of the thesis is to design and create an expansion board for the BeagleBoard computer one plate . The first and very important part was to find out all the possibilities for an extension of the computer itself . Choose the right expansion port . To study the possibility distribution of individual pins . Followed by the appropriate extension election districts that demonstrate the function of each enlargement . Test was designed PCB that contains circuits that change the voltage level of the BeagleBoard to protect a mini computer to the testing of each gusset periphery prevent damage to itself or part of the BeagleBoard . The peripherals themselves bind different parts of theoretical introduction. More specifically the extension of the LCD display is selected segment and includes two lines of 16 characters . When the possibility to add additional components were necessary to deal with the shortcomings of the output pins , this problem was solved by using an expander . He extends itself BeagleBoard by another 16 pins . On these pins are connected together on the LCD matrix keyboard . The creation of the board are two circuit temperature sensors , but have a different type of communication using I2C and one second using 1 -Wire bus . The board also contains various other bus outputs , for example, UART bus. It also contains an output pin which can be controlled PWM modulation . The remaining pins are versatile GPIO pins which can be programmed to define a function using the Linux operating system . The result is a final board of the package control programs which make it possible to verify the individual peripherals.

FLATcon system – CCD detection of media meters with RF communication
Lancz, Michal ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
Bachelor’s thesis deals with designing the concept of battery powered miniature microcontroller system based on CCD detection of media meters. The FLATcon design concept contains the necessary inputs and outputs for communication with microcontroller and with peripheral devices. The aim of the thesis is to detect the state of a media meter equipped with an analogue dial, to save the scanned image along with the scanning time and forwarding through the RF module. The bachelor thesis describes FLATcon system design, soldering and supplying the system and testing peripheral devices.

Mobile robot control system
Bugár, Loránt ; Jílek, Tomáš (referee) ; Hynčica, Ondřej (advisor)
Bachelors project is fixated for creating a mobile robot with a real time operating system. The robot control system is based on a microcontroller Arduino with ARM Cortex-m3 processor. The practical part is dealing with resolving the client-server communication with the UDP protocol, also with the identification of the engine from measured data’s by the Simulink and subsequently designing the PI regulator from the identificated data’s. In he last part of the work the focus is giving to solving the communication with I2C bus and using sensors like : accelerometer, ultrasonic sensor, infra sensor, light sensor, hall sensor and usage of a robotic arm. An application is created for controlling the robot and for visualisation of sensor readings..

Stopwatch for measuring of sports events
Tajč, Martin ; Petržela, Jiří (referee) ; Hruboš, Zdeněk (advisor)
The aim of this bachelor work is the construction of the electronic stop-watch for measurement at sports events. This stop-watch is primary designed for use at firefighters competitions. The first part of the work is focused on a flowchart of the stop-watch and an analysis of its parts. Some alternative methods, which could be used during the construction, are compared. In the following part, there is an algorithm for the microprocessor applied in it described and features of programming languages are briefly compared. Next in the text, there are a detailed user manual as well as a manual for executing of the display panel. In the supplement, particular electronic schematics and printed wiring boards are included.
