Design and Implementation of a Multitask Operating System Kernel Running on HC08
Damborský, Roman ; Růžička, Richard (referee) ; Strnadel, Josef (advisor)
Software for embedded systems is usually designed for performing one particular task. If there is need to serve more tasks at once, solution is used to be dedicated without potential reusability for another application. That is why I've designed an interface which allows simultaneous execution of single tasks independently of their character. Kernel is implemented in consideration of reusability. I analyse individual approaches to solution. I~used Round--Robin algorithm for implementing tasks management. Multitasking is achieved by periodical switching of single tasks. Interrupt subsystem is being used for this. As a target architecture, Motorola HC08 microcontrollers were chosen.

Building Heating System Controller Using Zigbee
Mičulka, Lukáš ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This thesis is focused on the design and implementation of heating controller system of the model house. In terms of design is the emphasis on simplicity, efficiency and scalability. Implemented heating controller system includes a central controller unit and modules that are placed around the model house and can perform several functions - temperature measurement, control actuators or remote parts of the wireless link. This thesis describes the complete development from the initial system design through assembly of all elements of hardware, firmware implementations for each module type and a control program running in the control unit. It also describes the communication between system elements. Suitably chosen solution combines wired and wireless connections, depending on how it is ideal in terms of the model house. The whole system of functional prototypes was tested and the results were summarized in the conclusion.

GameBoy Advance Emulator for Mobile Platforms
Vilímek, Hynek ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
The GameBoy Advance console was released by Nintendo in 2001 and it has experienced phenomenal success during its existence. It used to control the majority of the market at one time and partly due to this it has become synonymous with portable gaming consoles. This popularity was gained especially thanks to the games developed for it. They have become so popular that even today there is a demand for them. These games, however, are not played on the original consoles but on today's mobile devices. And since current mobile devices are technologically very different from the console, it is necessary to run these games via an emulator.

Robotic Manipulator Controlling Using Microcontroller
Zemánek, Martin ; Škarvada, Jaroslav (referee) ; Růžička, Richard (advisor)
This master's thesis deals with control robotic manipulator ROB 1-3 using common joystick and microcontroller HC08 NITRON or HC08 LJ12. The goal of this work was creation of module for controlling axes position of servos included in robot by analog signal coming from connected joystick. There are formed possible suggestions about connecting individual parts together for both autonomous and version using development kit. Programming code suggestion is based on these connections during further development. The limitations of using it are described in analysis and final results are shown in statistics results.

USB Key
Slimařík, František ; Růžička, Richard (referee) ; Strnadel, Josef (advisor)
These days USB interface belongs to the most used interfaces for communication between computer and external devices. It must satisfy strict requirements to be provided its multiplatformity. In the process this interface found its use even in microcontrollers. This thesis is focused on design, compilation and programming of hardware USB key of HID standard with usage of microcontroller MC68HC908JB8.

HC08-Based Controller of a Step Motor
Hájek, Josef ; Růžička, Richard (referee) ; Strnadel, Josef (advisor)
This bachelor's work deals with issue of stepper motors and their control using single-chip microcontrollers. Target of the work is to be familiar with method of operation of stepper motors, with their abilities and restrictions in case there are used in built-in devices. The part of the work is a proposal of control unit of chosen stepper motor and interconnection with developmental kit 908LJ12-G2. Implementation part of the work contains software for eight-bit microcontroller Motorola MC68HC908LJ12 programmed in language C. The stepper motor can be controlled by this program using the available kit's interfaces.

HAM Station Log Book for Linux
Kaluža, Jan ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
The goal of this bachelor's thesis is to design and implement an amateur radio logbook software for a GNU/Linux operating system. After the short introduction there are described existent logbook applications together with analysis of their advantages and disadvantages. Based on this analysis the logbook application is designed and implemented. Finally, there is a summary and discussion of possibilities for further improvements.

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.
