DMX 512 protocol analyzer for personal computer
Brouček, Vilém ; Juráň, Radovan (referee) ; Krajsa, Ondřej (advisor)
This bachelor thesis consists of designing and assembling an USB–DMX512 analyzer. It contains detailed information about the protocol itself, particularly the structure of the signal and its physical layer. It discusses options for analyzing the signal, chooses an appropriate microcontroller unit and provides a draft of a hardware for the controler. The thesis describes the assembled analyzer, explains its functions, the selection of components, and the principles of PCB design. It also explains the usage of the device and its potential future upgrades. The thesis provides a description of the code for the STM32 microcontroller and the custom-made libraries used for the DMX512 packet analysis and creation. It then familiarizes the reader with the code of the personal computer application, the reasons for choosing C# as the main programming language, and explains the structure of the object-oriented code, along with the custom-made libraries for DMX512 packet generation and analysis of the received data. The result of the thesis is a working DMX512 analyzer, which can receive and transmit the signal, display transmitted data, and connect to a PC via the developed software.

Lighting system for auditorium
Novák, Marek ; Kubásek, Radek (referee) ; Friedl, Martin (advisor)
V této bakalářské práci je uveden návrh a realizace osvětlovacího systému, který svou specifikací překonává možnosti široce rozšířeného protokolu DMX512/RS485. Dále jsou zde popsány omezení tohoto protokolu a také protokolů CAN bus a 100BASE-TX. V závěru je pak navržena síťová topologie, která je vhodná pro řízení daného počtu koncových prvků, spolu se samotným koncovým prvkem (řízeným světlem).

Wireless Signal Transmission of DMX512 Interface
Polóni, Pavol ; Jaroš, Jiří (referee) ; Šimek, Václav (advisor)
Master's thesis deals with design and implementation of a system for wireless transmission of DMX signal 512, which is primarily designed for the management of lighting effects. Its electrical specification is based on the EIA485 standard. Text of the work describes the design stage. First is the issue of implied actual protocol DMX 512 or EIA485. Next sign on selecting a suitable architecture for wireless transmission, management and compilation of the block diagrams. Describes the operation of the component selection and circuit implementation of the scheme, which is using the DPS Eagle compiled. In conclusion, this work is to evaluate the results of the proposed system and showing the way to its further development so that it can be realistically implemented in practice.

DMX console for stage lighting control
Schilhab, Jan ; Chladil, Ladislav (referee) ; Čech, Ondřej (advisor)
The bachelor thesis deals with the question of controlling stage lighting using the DMX 512 protocol. The thesis describes the function of this protocol in details and compares several types of commercially available lighting consoles. The comparison shows some functions and features of the consoles, which are used to design the concept of the actual console. The main part of the thesis is the design of the circuit blocks of the lighting console and a description of the implementation of a functional prototype. The development of the entire control software is also an integral part. The work is concluded with an evaluation of the achieved features and functions of the implemented device.

Advertising LED RGB Tube with Control Unit
Frelich, Marek ; Fedra, Zbyněk (referee) ; Frýza, Tomáš (advisor)
This project discusses design of LED RGB tubes, which can be driven by asynchronous serial line. The light color of the LED tubes can be controlled in a several segments of tubes. There is made a design of control unit for driving LED tubes, which contains circuits for receiving and detection of audio signal, receiving of protocol DMX512 and also driving of LED strips. For the microprocessors there is also created a software which ensures a communication between the control unit and LED tubes, driving LEDs in the tube and creating various lighting effects.
