FPGA controller for LED video display
Dolejší, Miloš ; Bečková, Zuzana (referee) ; Hanák, Pavel (advisor)
This thesis deals with controlling a color graphic LED display using an FPGA. The first half of the theoretical part of this paper describes the properties of the used FPGA, the data source and a principle of controlling an RGB LED display. The second half describes an implementation of pulse width modulation and binary code modulation which enables the control of brightness of the display and of color depth of every sub-pixel. The practical part on the other hand describes the designing and the implementation of this module in the VHDL language. Then it explains the transfer of image data from Blackfin processor to the memory via PPI interface, the subsequent process of reading data from the memory, conversion of the data to a serial format and finally it describes the process of sending the data to the LED controller. The module was realized on the Digilent Atlys development board equipped with the Spartan-6 FPGA and was tested on a 32x20 light panel for the firm Ing. Ivo Herman, CSc.

Application for Programming MIDI Controllers
Dolejší, Miloš ; Frenštátský, Petr (referee) ; Schimmel, Jiří (advisor)
This bachelor thesis deals with designing of an application which allows programming of controls on ControlFREAK and Bitstream 3x controllers via MIDI System Exclusive messages. The theoretical part contains an analysis of the MIDI communication protocol, including description of channel and system MIDI data. The practical part describes individual parts of the application and then presents and explains parts of the source code. The application has been created in the Visual Studio 2013 SDK using Windows Multimedia System library, which contains functions and structures necessary for accomplishing the application’s tasks. The communication between the PC and the controller is realized via MIDI-USB converter.
