[Elko EP] Access Point for Wireless Control System of Electrical Appliances
Vrana, Ondřej ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This work is concerned with development of module for communication with intelligent instalation into houses system. The aim was to familiarize with the products of RF Control of ELKO EP, s.r.o., USB bus and wireless communication components for the 868 MHz band. And afterwards, in cooperation with the ELKO EP company, to design an electrical scheme and printed circuit board motive of this module. For cooperation with the module and for the system components control an aplication was programmed. The application name is RF-AP USB.

Numeric keyboard
Hladký, Pavel ; Novák, Lukáš (referee) ; Šteffan, Pavel (advisor)
This thesis deals with design of numeric keyboard, which can be connected to personal computer or laptop through USB interface. This numeric keyboard can be also configured using application for operating system Windows. Backlight pattern generator is also part of this application. Theoretic part deals with various types of keyboards, switches and closer description of USB interface. Practical part deals with sole design of circuit that detects keystrokes and sends information about active switches through USB, description of used components, description of microcontroller service routine and description of the application for backlight pattern generating. At the end of this thesis are described results of measurements which were made to choose mechanical switches with shortest debounce time and keyboard response to key press.

Design of mechanical keyboard
Pillár, Andrej ; Dobrovský, Ladislav (referee) ; Šoustek, Petr (advisor)
Tato práce představuje konstrukci počítačové klávesnice využívající mechanické spínače kláves. V první části je uveden stručný přehled historie počítačových klávesnic, použitých technologií, standardů a možností. Následuje přehled klávesnice navržené v rámci této práce. Realizovaná klávesnice je založena na spínačích JWK Everglide Oreo ve stylu Cherry MX umístěných na PVC desce. Klávesnici ovládá firmware QMK běžící na 32-bitovém ARM mikrokontroleru. Klávesnice je vybavena upravenou mapou kláves a je plně programovatelná. Mezi další funkce patří programovatelný otočný enkodér a vícebarevné podsvícení kláves.
