Extensible Rust Library for the Development of Embedded Sensor Applications on ESP32 Platform
Mikhailov, Kirill ; Tinka, Jan (referee) ; Šimek, Václav (advisor)
Tato práce představuje rozšiřitelnou knihovnu jazyka Rust určenou pro vestavěné senzorové aplikace na platformě ESP32, která řeší potřebu zjednodušeného vývoje reálných vestavěných systémů v prostředí jazyka Rust na této platformě. Významným přínosem této práce je vývoj uživatelsky přívětivého rozhraní pro správu senzorů. Toto rozhraní umožňuje jednoduchou instalaci, aktivaci a monitorování senzorů, což vyhovuje aplikacím, jako jsou inteligentní domy a automatizace, aniž by vyžadovalo hluboké technické znalosti periferií. Architektura knihovny je pečlivě navržena s ohledem na modularitu a rozšiřitelnost a dodržuje zásady bezpečnosti a efektivity Rustu. Projekt je doprovázen rozsáhlou dokumentací a je zveřejněn na platformě GitHub pod open-source licencí Apache, doplněn unit-testy a příklady použití. V závěru práce je zhodnocena funkčnost knihovny a její případná budoucí vylepšení, která ukazují její praktičnost pro vývojáře vestavných systémů.

Development kit for capacitive touch sensors analysis
Večeřa, Marek ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This bachelor thesis adresses the topic of capacitive touch sensing for use in electronics with evaluation on dedicated microcontroller peripheral, or on a dedicated integrated circuit. At first there are presented various ways of capacitive sensor design and their evaluation methods. Secondly in practical chapter I introduce a design of development kit with implementation of different capacitive elements on the STM platform, whose sensitivity and efficiency is evaluated and compared to integrated circuit dedicated to capacitive sensing.

Programmable attenuator for laboratory measurement
Husslik, Tomáš ; Šimka, Marek (referee) ; Polák, Ladislav (advisor)
This thesis deals with the design of a programmable attenuator with digital control. The main objective of the work is to design and create an attenuator with a nominal impedance of 50 , providing adjustable attenuation in the range of 0 to 40 dB, functioning within a bandwidth of 1 to 2 500 MHz. Control of the proposed attenuator is facilitated by a microcontroller that manages the settings of an integrated circuit attenuator. Furthermore, the attenuator features a basic user interface. A PCB was designed for the attenuator and subsequently manufactured. The device was then assembled and its key parameters were measured.

Wireless Rotary Head for Scanning Internal Surfaces
Horák, Rostislav ; Strnadel, Josef (referee) ; Malaník, Petr (advisor)
The purpose of this project is to create wireless rotary head for scanning internal surfaces. Which includes design and implementation of device with static and rotary parts. The two parts communicate wirelessly and the rotary part is also wirelessly charged. That enables continuous rotation and measurment. Another part of project is data collection from sensors and communication between parts of the device and also with external world. Focus is given to wireless communication using IR light, wireless power transfer and control of stepper motor. Project describes technologies and principles on which it is based, design and implementation of hardware and software, presentation of achieved results.

Cryo Tubes 2D Codes Scanner
Anděl, František ; Holoubek, Tomáš (referee) ; Matoušek, Radomil (advisor)
This bachelor’s thesis concerns the design and construction of a prototype two-dimensional code scanner placed at the bottom of cryotubes, which are stored in a cryogenic rack in the SBS (Society for Biomolecular Sciences) format. The theoretical section discusses the design and use of cryotubes, storage systems, and marking methods. It also describes the existing scanning methods, anti-fogging solutions, optical sensors, electromechanical elements and gears, microcontrollers, and single-board computers. The practical part of this thesis is devoted to the design of the mechanical structure and production of a prototype using 3D printing. This is followed by testing the functionality of the solution for collecting code images of sufficient quality and designing a solution for transferring the code image to the computer.

Adaptation of Zephyr RTOS and Sound Open Firmware on a HiFi4 DSP of the NXP i.MX RT685 MCU
Staniček, Vít ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
Tato práce se zabývá analýzou mikrokontroléru i.MX RT685 vyráběného firmou NXP Semiconductors, v něm realizovaného Tensilica HiFi 4 DSP jádra a popisuje úsilí adaptace RTOS Zephyr společně s vrstvou Sound Open Firmware na tuto platformu. Aplikace demonstrující zpracování digitálních zvukových signálů nad těmito technologiemi je v této práci implementována rovněž. Práce je motivována záměrem jak efektivně realizovat techniky pro digitální zpracování zvukových signálů na této platformě, tak sjednotit jejich použití.

Picobaloon s využitím low-power bezdrátových sítí
Kudera, Matěj ; Peringer, Petr (referee) ; Janoušek, Vladimír (advisor)
Aim of this master thesis was to create a small meteorological probe (PicoBaloon) which can record its position and basic meteorological information. Information recorded by this probe has to be transmitted to the user so it can be evaluated. Theoretical portion of this work describes how to create this type of device and which technologies can be used for its implementation. Next, information describing what exactly PicoBaloon is are presented, which are then used to form requirements for this system. Based on described technologies and system requirements final system design was created. Created system consists of two parts. First part is the probe itself which is created on its own piece of printed circuit board. Probe is controlled by a small microcontroller and consists of components that can generate power with a small solar panel, determine its position with GPS, record meteorological information and send recorded information to the user with wireless technology. Second part of the created system is a web application which presents recorded data to the user. At the end of this thesis physical creation and testing of this system is described.

Racecar Dash
Listoň, Martin ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The topic of this thesis is displays for racing cars. It includes a summary and brief comparison of the different types of displays as well as the current range of panels available from commercial brands. The following part of the thesis is devoted to the implementation of the creation of a custom display panel, which consists of primary scanning, testing and subsequent laboratory simulation, as well as the creation of the PCB design for the display interface from the vehicle's CAN bus, the compilation of the final code in the Arduino IDE software environment, the creation of the GUI (Graphical User Interface) in the Nextion Editor program, and also the structural design of the instrument panel including printing and assembly. The final part of the thesis is the verification of the functionality of the created complex device and the evaluation of the results. The main goal of the thesis is to create a functional complex device that is more affordable than the currently offered devices on the market.
