Embedded System for Water Level Monitoring
Hanák, Jiří ; Kašpárek, Tomáš (referee) ; Šimek, Václav (advisor)
This work is dealing with the design and implementation of an embedded water level monitoring system. The purpose of the system is to control the filling of a tank based on the water level. First of all, the attention is given to the survey of existing measurement techniques and selection of the appropriate sensing elements for a given scenario. In fact, the embedded system is using TFmini and JSN-SR04T-2.0 contactless sensors. The system is controlled by STM32F0 microcontroller from STMicroelectronics programmed in C using HAL abstraction layer. The measured results are sent via Wi-Fi SoC ESP8266EX to the Python server that is used for processing and demonstratiton purposes.

Self-Testing of Microcontrollers
Denk, Filip ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This Master's thesis deals with functional safety of electronic systems. Specifically, it focuses on self-testing of the microprocessor and its peripherals at the software level. The main aim of the thesis is to design and implement a set of functions written in programming language C or assembly language, which automatically test the selected areas of the microcontroller. Resources and methods used in the implemented solution also aim to meet the requirements according to the safety standard IEC 60730-1, Annex H, Software Class B. The microcontroller NXP LPC55S69 was chosen as a hardware platform. It consists of two ARM Cortex-M33 cores. As a result, the example application is provided, which uses implemented test functions at the run-time. Example application also contains a graphical user interface with fault injection ability.

Component Interconnection Inference
Olšarová, Nela ; Rychlý, Marek (referee) ; Křivka, Zbyněk (advisor)
The Master Thesis deals with the design of hardware component interconnection inference algorithm that is supposed to be used in the FPGA schema editor that was integrated into educational integrated development environment VLAM IDE. The aim of the algorithm is to support user by finding an optimal interconnection of two given components. The editor and the development environment are implemented as an Eclipse plugin using GMF framework. A brief description of this technologies and the embedded systems design are followed by the design of the inference algorithm. This problem is a topic of combinatorial optimization, related to the bipartite matching and assignment problem. After this, the implementation of the algorithm is described, followed by tests and a summary of achieved results.
