The FITkit3 Tester
Stehlík, Petr ; Strnadel, Josef (referee) ; Bidlo, Michal (advisor)
This work solves the problem of testing a certain set of ARM Kinetis Cortex-M4 \newline (MK60DN512ZVMD10) microcontroller modules on the FITkit3 learning platform (also known as Minerva). Specifically, it deals with the design of test firmware in the C programming language for automated testing, the design of a hardware module for testing platform input/output interfaces using the MCP23S17 integrated circuit and the design of a software with text-based user interface in Python3 for the testing control from a PC. The selected test set of modules are Periodic interrupt timers (PIT), Low-power timer (LPTMR) and Real time clock (RTC), further modules for serial data transmission via UART and SPI interfaces, speaker and GPIO ports. The created solution provides a comprehensive tool for analysing the functionality of frequently used modules on FITkit3, which automates the analysis process almost completely. The main benefit of this work is the facilitation of testing and a rapid detection of errors in a large number of kits.

Modular RGB LED display with Ethernet
Zemánek, Petr ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with an electronic circuit and a PCB of a modular RGB LED display with the Ehernet interface. Firstly, author describes a RGB colour model, features of RGB LED displays, ways of control them. The next chapter contains a short description of the Ethernet interface, UDP and TCP protocols and a lwIP TCP/IP stack. The last theoretical chapter is an introduction to ARM Cortex-M3 and Cortex-M4 based microcontrollers. The next chaper is deals with a hardware design of the modular RGB LED display. The device is designed to be modular. Individual devices can be combosed together and create a larger display. Data from the Ethernet interface will be displayed on the RGB LED matrix, resolution of the matrix is 32 × 32 (1024 diodes). A refresh frequency is 100 Hz, a color depth is High color (16 bits) and a scanning 1/16 (two rows is driven at the same time). The next chapter describes the firmware for the RGB LED display, all its logical parts including a web page. Author also created the PC application, which sends pictures using UDP protocol to individual modules.

Preventing Computer System from Computational Overload Due to Interrupts
Hajdík, Tomáš ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The master thesis deals with the techniques to prevent computer system from computational overloading due to excessive frequency of interruptions. The goal is to document the effect of interupts on a selected computing platform containing the ARM Cortex-M4 processor core. The work describes and implements possible software techniques that reduce the impact of consequences of overload due to excessive interruption frequency. At the same time the work verifies and compares the effectiveness of the particular implemented techniques by appropriate set of experiments.

Implementation of Software for RC Radio
Faltičko, Martin ; Bidlo, Michal (referee) ; Vašíček, Zdeněk (advisor)
This document deals with the control software for professional Model-radio transmitter. The aim of the thesis is to design a functional solution that would satisfy the requirements of existing aircraft modelers (and others), thus to compete against other manufacturers of radio sets. In the following pages there is presented the design and implementation of user interface with regard to functionality and clarity, then the basic algorithms for driving aircraft models are explored. As a result of those findings the control software is implemented for an embedded device using the supplied hardware components.
