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.

Data logger for Gas Boiler
Frnka, Peter ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This bachelor thesis deals with design and realization of a datalogger designated for logging data acquired gas boiler controls. The gas boiler controls are under development by Honeywell Brno. The datalogger is implemented on Raspberry Pi hardware platform with voltage converters supplied by Honeywell Brno. Measurement application, which is part of datalogger firmware was developed in C programming language. All data that are measured during datalogger runtime are stored on data storage. The measured data are presented to the user by a web application. The web application and data storage are put into operation on the main server, which is the part of local network in Honeywell Brno. In result of this thesis, data logging system capable of collecting data from furnace controls was developed. Created device helps with research, development and testing of furnace controls.
