USB HID Monitor
Budai, Ondřej ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
The goal of this thesis is to design and implement application for in-depth analysis of USB HID devices’ structure and communication. The resulting application is capable of visualization various information retrieved from device. It can handle bidirectional communication between computer and HID device and it’s available for operating systems Windows and GNU/Linux under libre software license. Application with this set of features currently does not exist. Thus, its creation is really beneficial for all USB HID developers.

NiCd, NiMH and Li-ion accumulator charger supplied and controlled via USB
Nosek, Petr ; Mišurec, Jiří (referee) ; Zeman, Václav (advisor)
Deals with analysis and battery charging NiCd, NiMH, Li-Ion through a series of microcontroller from Atmel AVR controlled and powered from a PC via USB. Part is devoted to the characteristics of the USB interface and software capabilities to the enumeration AVR microcontroller. It also contains the basic characteristics of charged batteries, including the known methods of charging. The second half of the tehesis then provides a complete design and implementation of battery chargers, which consists of electronic parts, ATMEGA168 microcontroller program and the program for the PC. Presents circuit diagram of the charger and flowcharts of the main features of the program. The result of this thesis is functional battery charger above types. Attachments include a proposal DPS, a full circuit diagram and the charge and discharge characteristics of cells. The thesis is also referred to annex to the optical disk. Here it is mainly programs for microcontroller and PC. They are listed here as well as individual projects for AVR Studio, Borland Builder C + + and Eagle, which was created by chargers.

Adjustable source supplied and controlled via USB
Pavlíček, Petr ; Daněček, Vít (referee) ; Zeman, Václav (advisor)
Master’s thesis deals with design and realization of power supply, which is supplied and controlled via USB bus. In theoretical part there are described principles of USB communication drivers which ensures this communication, there are described principles of linear voltage regulators and basic types of DC/DC converters. Mentioned is also PID regulator theory. Practical part aims for design of suitable DC/DC converter topology and creating algorithms for driving this converter. Next there is created PC program which drives power supply and there are also accomplished basic power supply measurements. The result of this thesis is functional power supply supplemented with PCB.
