Distance meter with ESP32
Havelka, Jan ; Hanák, Pavel (referee) ; Lattenberg, Ivo (advisor)
The aim of this thesis was to implement a distance meter with two sensors (ultrasonic and laser) with an ESP32 microcontroller. Then the ability to display measured values on the display and via the web interface. The first part deals with the theory of ultrasound and laser, their use as distance meters and a summary of advantages and disadvantages. The following chapter describes the design of the distance meter with all the components that will be used. The third chapter focuses on the implementation of the distance meter. It was created wiring diagram and designed printed circuit board that handled all mutual communication between the ESP32 and other peripherals. The whole device is placed in a box in the shape of a pistol printed on a 3D printer. The next part of the work briefly describes the software of the distance meter written in the C programming language in the development environment Arduino IDE. Finally, images of the final product were inserted into the work and test measurements were performed, the result of them is written into tables, graphs and subsequently evaluated.

Development kit for microcontrollers communication with computer
Franek, Miroslav ; Novák, Lukáš (referee) ; Levek, Vladimír (advisor)
Master’s thesis deals with the design of development kit for communication between a microcontroller and a computer using USB, Bluetooth, WiFi and Ethernet interfaces. In the theoretical introduction is the analysis of theese interfaces and the interfaces used for communication by the microcontroller. In the next part, components for the development kit are selected. Then a wiring diagram and the printed circuit board is designed. Next, the firmware design is described. The last chapter deals with the implementation and testing of the development kit. The appendix contains a proposal for a laboratory task to introduce the development kit to students.

Control of graphic OLED display with Atmel microcontroller
Bartošík, Vladislav ; Lattenberg, Ivo (referee) ; Hanák, Pavel (advisor)
This Master's thesis deals with design and a realisation of a device controlling an OLED display, Densitron DD-25664-1A. This display has a resolution of 256 x 64 pixels and allows displaying of 4-bit grayscale. The proposed utility software implements the initialization and termination functions, two sets of fonts { Latin and Greek letters and functions for rendering graphics and text. The result of the project is a device with the controlling software.

Embedded QR code generator with a graphic OLED display
Lakomý, Tomáš ; Krajsa, Ondřej (referee) ; Hanák, Pavel (advisor)
This master’s thesis deals with coding information and QR codes generating. There is described operation principle of QR codes for this purpose, and design of the equipment. This device is able to encode the information received through the serial port and display it in the QR code on the OLED display. Microprocessor is part of the device, so there is outlined the procedure for programming and testing equipment.

Inovation of laboratory tasks from BLOS
Urban, Jakub ; Valach, Soběslav (referee) ; Holek, Radovan (advisor)
This thesis deals with innovation of tasks from bachelor subject Logical systems. Three tasks in total in VHDL language were designed and tested for development kit Digilent Nexys 3 and peripheries Pmod which are connected to it. First task is focused on reading pressed key on matrix keyboard. Second and third tasks targets on displaying pressed key on OLED display, they differ by used controller for this display. Instructions for all tasks were created.

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.
