Development Board for 32-bit Microcontroller Atmel AT91SAM9261
Demín, Martin ; Slaný, Karel (referee) ; Šimek, Václav (advisor)
Vestavený hardware je velice populární v této době. Proto jsme se rozhodli vytvořit desku s mikrokontrolérem AT91SAM9261 spolu so standartným a nestandartným hardwarem. Standartným, běžným by se dal nazvat port LAN alebo audio vstup-výstup. Nestandartným, špecialním by mohl být obvod FPGA firmy Xilinx o velikosti 200k. Toto dovoluje využít zažízení v oblastech, kde výpočetní síla obyčejnýho CPU již není dostačující.

Intelligent LED Light
Krejčí, Martin ; Frýza, Tomáš (referee) ; Povalač, Aleš (advisor)
The aim of the bachelor thesis is to design and implement a prototype of intelligent LED lighting with the possibility of mixing colours (cold white, warm white, red, green and blue) and with integrated motion, smoke, temperature and pressure sensors, which can be connected to an island photovoltaic system. Create a control unit and a W(LAN) unit that will allow communication outside this closed bus using a web interface. Establish appropriate and reliable communication between all proposed system units. The thesis first describes lighting, its history and the use of multi-colour LED lighting today. Then all the buses used are described. The design of the device itself consists of a 3D model of the prototype LED lighting embedded in the ceiling, followed by the selection of the specific integrated circuits, microcontroller kits and other peripherals needed. At the end of the paper, the measurement results of all the designed components of the device are summarized.

Automated measuring system for irrigating plants with IoT connectivity
Lahoda, Vladimír ; Polák, Ladislav (referee) ; Kufa, Jan (advisor)
This bachelor thesis deals with IoT networks and considers their use as part of embedded devices. The purpose of this device is to control the flower bed or garden based by data from sensors monitoring the environment. The device not only controls the irrigation operation itself, but also sends all traffic data over the IoT LoRa network. Thus, the device also functions as a weather station, as all data are sent to a second device that acts as a receiver. This receiver displays the data and also sends them to the Internet, where the data are publicly available. The module for sending and measuring data is mounted on its own PCB and is covered in a waterproof cover, so they can be operated outdoors. There is an integrated battery, which is a backup of savings in case of power failure. The battery is designed to back up power for 25 days.

Embedded system design
Gábor, Tomáš ; Galetka, Josef (referee) ; Götthans, Tomáš (advisor)
This work deals with application of ARM based development board as platform for remote controlling of attached peripherals. It describes practical experiences with A20- OLinuXino-Micro-4GB development board and it’s available options. Used hardware and testing peripherals are described in the next part along with programming of the software for web interface and for communication in between development board and peripherals. The second half of this document describes design process of own embedded system beginning with schematic, continuing with PCB wiring. Each step of PCB wiring process is described with required details in text, including crucial connections between processor and memory chips. The last part contains details about setting a calibration of memory chips and designing optional peripheral modules.

Production Cell for Industry 4.0 testbed
Byrtusová, Lucie ; Jirgl, Miroslav (referee) ; Baštán, Ondřej (advisor)
The bachelor thesis is focused on Warehouse production cell, which is a part of the industry testbed 4.0. The first part analyzes the completion of mechanical design of the cell. Furthermore, the thesis deals with the electronic equipment of the cell, including the desing of the electrical wiring, to which electrotechnical documentation was elaborated. The described equipment is process instrumentation and control elements. In the instrumentation are included actuators and sensing elements. The control elements in the cell are PLC, motor drivers and HMI panel. Part of the thesis is devoted to the desing of the embedded driver firmware of unipolar stepper motors. Next part deals with software solution of the cell including PLC and visualization. The final part describes the achieved results.

Implementation of Deep Learning Algorithm on Embedded Device
Ondrášek, David ; Boštík, Ondřej (referee) ; Horák, Karel (advisor)
This thesis deals with the implementation of inference model, based on the methods of deep learning, on embedded device. First, machine learning and deep learning methods are researched with emphasis on state-of-the-art techniques. Next, the best suitable hardware had to be selected. In the conclusion, two devices are chosen: Jetson Nano and Raspberry Pi. Then the custom dataset, consisting of three classes of candies, was created and used for training custom inference model through the transfer learning technique. Model is later used in the application, capable of object detection. Application is implemented on Jetson Nano and Raspberry Pi and then evaluated.

Asynchronous MQTT Client Library for Embedded Devices Running on Drogue-IoT Firmware
Babec, Ondřej ; Lichtner, Ondrej (referee) ; Pluskal, Jan (advisor)
IoT je odvětví informatiky, které v posledních letech masivně expanduje. V dnešním světě je IoT všude kolem nás. Jsou to chytré žárovky a doplňky do domácnosti, ale také tisíce zařízení v průmyslových objektech. Nedílnou součástí IoT jsou protokoly pro zasílání zpráv, které umožňují komunikaci komunikaci s těmito zařízeními. Dnes již existuje mnoho projektů, které umoňují integraci IoT zařízení a následné cloudové zpracování jejich zpráv. Jedním z těchto projektů je Drogue-IoT. Tento open-source projekt umožňuje vytvářet firemní cloudové řešení, ale také firmware pro vestavné zařízení. Jednou z limitací tohoto projektu je nepřítomnost klientské aplikace podporující zasílání zpráv pomocí protokolu MQTT. Právě tato klientská aplikace je tématem této práce. Práce zahrnuje návrh a implementaci klienta protokolu MQTT pro vestavěná zařízení v jazyce Rust, který doposud neexistuje. Řešení je demonstrováno pomocí sestrojeného zařízení. Výsledná práce vyhodnocuje implementaci klienta a obsahuje návrhy na budoucí vylepšení práce.
