The aim of this work was to create a communication interface of standard ARINC Aerospace Industry Bus 429. The work has slightly outlined existing solutions, from which it can draw inspiration. Further analysis was performed, analysis of ARINC 429 bus, analysis of Raspberry Pi platform on which the solution will be built, and analysis of selected bus controller HI-3593. After that concept was created, based on concept was created the scheme contains circuitry HI-3593. On the basis of the scheme was created DPS. Next was created software for DPS. In the end of this work was tested abilities to receive and send messages on the bus ARINC 429.

Nowadays, the interest in smart appliances, which enable consumption reduction or consumption shifting approach, grows up. Such appliances can react to actual situation in the distributional network. From the energy distributor point of view, the activity of these appliances brings improvement of stability in the distribution network, while for the end customer there is possibility of the saving money. This thesis describes a transformation of standard fridge to smart fridge controlled by microcomputer Raspberry Pi. The smart fridge can communicate with supervisor system and according to its instructions change its behavior (temperature set point). The appliance can be manually controlled by a group of buttons, while its state can be visualized on the alphanumeric display. Last but not least way to control the appliance is through a web interface. The thesis also describes design of printed circuit board (PCB), which is designed for connection of all necessary sensors and actuators to Raspberry Pi. Software equipment is designed in the C++ program language.

Företag kan ha produktionsanläggningar på ett antal olika platser runt om i världen. Den industriella utrustningen som används i anläggningarna innehåller ofta någon form av inbyggt system som kräver underhåll eller övervakning vid jämna mellanrum. Utrustningen kan vara tekniskt avancerad och därför måste underhållet skötas av en servicetekniker. Mindre leverantörer av industriella utrustningar har inte alltid möjlighet att ha serviceorganisationer i varje land då detta innebär en extra kostnad. Det hade därför varit fördelaktigt med ett kompletterande kommunikationssystem som fungerar som en mellanhand mellan servicetekniker och målsystem som kan befinna sig på skilda platser.Kommunikationssystemet som tagits fram i detta projekt fungerar som en typ av fjärrövervakning där det är möjligt att utföra fjärravläsning samt ändra inställningar på distans. Syftet med examensarbetet är därför att utveckla en enkel och kostnadseffektiv enhet avsedd för fjärrövervakning av utrustningar innehållande inbyggda system.Examensarbetet resulterade i en kostnadseffektiv prototyp av en övervakningsenhet, baserad på enkortsdatorn Raspberry Pi, som kan kopplas in till ett målsystem när service behövs. I projektet testades kommunikationssystemet mot ett målsystem baserat på enkortsdatorn Arduino Uno. Övervakningsenheten har möjlighet att kommunicera med målsystemet via tre olika sätt: RS-232, JTAG samt kommunikation via GPIO-pinnar. Dessa kommunikationssätt kan användas till olika ändamål då kommunikationssätten är användbara för olika tillämpningar och kan därmed möjliggöra implementering av många olika funktioner. Kommunikationssätten är dessutom välanvända och passar till många olika målsystem. Servicetekniker har två tillgängliga användargränssnitt för att interagera med övervakningsenheten. Det primära användargränssnittet är ett webbgränssnitt där utdata från målsystemet kan övervakas samt att det finns möjlighet att ställa in olika inställningar. Det andra användargränssnittet består av fjärrstyrning av övervakningsenheten där funktioner finns för att utföra felsökning (eng. debugging) samt möjlighet att ladda in ett nytt program på målsystemet. / Companies can have production plants in a variety of locations around the world. The industrial equipment used in facilities often includes some form of built-in systems which require maintenance or monitoring at regular intervals. The equipment can be technologically advanced and therefore maintenance must be performed by a service technician. Smaller suppliers of industrial equipment are not always able to have service departments in each country, which often means an additional cost. It would therefore be advantageous with an additional communication system that acts as an intermediary between the service technician and the target system that can be located in different places.The communication system developed in this project acts as a kind of remote monitoring where it is possible to perform remote reading, and change different settings remotely. The purpose of this study is therefore to develop a simple and cost effective device designed for remote monitoring of equipment containing embedded systems.The study resulted in a cost-effective prototype, based on the single board computer Raspberry Pi, of a monitoring device that can be connected to a target system when service is needed. The communication system was tested throughout the project on a target system based on the single board computer Arduino Uno. The monitoring unit is able to communicate with the target system via three different ways: RS-232, JTAG and communication via GPIO-pins. These communication methods can be used for different purposes as these communication methods are useful for various applications and can thus enable implementation of many different functions. The communication methods are also widely used and suitable for many different target systems. Service technicians have two available user interfaces for interacting with the monitoring unit. The primary user interface is a web interface where the output of the target system can be monitored and that there is the possibility to set different settings. The second interface is remote controlling of the monitoring device which has functions to perform debugging and the ability to flash a new program into the target system.

This diploma thesis deals with the research of existing solutions of electronic information systems. The purpose of this survey is to inspire what is offered to users of these professional systems, or what users expect from these systems. Based on the acquired knowledge, the thesis also deals with the design of its own system, which can serve as another alternative to professional solutions of companies on the market, in the sense of the concept of solution of the given task. After the design of the system, the thesis deals chronologically with the selected "tools" used for the actual implementation of the assigned task Electronic Information Boards. Both hardware and software parts of the task, which form the majority of this thesis. At the end of the work are presented practical results.

This master's thesis is describing problems of embedded systems and their development. Furthermore, the operating system GNU/Linux and it's cross-compiling is described. Hardware problems are analyzed too. Concrete solution is system which is able to boot from the USB disc and it is based on OpenWrt distribution running on Edimax BR-6104KP router. The whole solution is described the way which can lead to any general embedded system.

The master’s thesis describes development of control system for automatic mouth-organ. The process of development is divided into three parts: a concept of control system, design of hardware parts and development of software parts. Controlled device, system requirements and general design of the hardware and software components are described in the concept of control system. The detailed hardware design includes next processes: electronic component selection, printed circuit board design, assembly and debugging. The result of this chapter is electronic system, which function correctly. The aim of the last chapter is to specify and explain development of software parts of control system. Installation of required software and important aspects of control software and user interface development are described in this chapter. The goal of the thesis is to create a control system, which will function correctly and reliably.
