Emulation of Character-Based LCD Display Using E-Ink Technology
Rusín, Tomáš ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The aim of this bachelor thesis is to design a simple printed circuit board interconnect. The board is planned to be equipped with a microcontroller that will receive communication signals originally intended for LCD character displays. The communication may be parallel or serial, in the form of SPI and I2C type interfaces. These signals are planned to be received and converted to E-Ink display signals. That display will show information in the same format as it was designed for LCD displays. The E-Ink display replaces LCD displays without the need of changing the original library or the original communication interface. This method of replacement is suitable when a LCD character display is destroyed and a suitable replacement cannot be found, or when the E-Ink display is more suitable.
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.
Prototype of Touchless Musical Instrument
Pilný, Tomáš ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
In this thesis is described the motivation to create a touchless musical instrument as a platform for live musical performance. Thesis contais the overview of existing electronic musical instruments. Furthermore, it describes process of design and implementation of a prototype.
Theremin: Touchless Musical Instrument
Baštýř, Lukáš ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This bachelor thesis deals with the design and implementation of a digital touchless musical instrument theremin. In the first part, the theremin, its features and existing solutions are first documented. The second part focuses on the documentation and testing of the software and hardware that can be used to solve this thesis. The penultimate part focuses on the actual implementation of the instrument and the creation of a working prototype. The final section tests functionality of the final prototype instrument.
Design and Analysis of Systems for Advanced Guarding and Securing Objects and Areas
Komínek, Petr ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This diploma thesis deals with design, realization and analysis of security and surveillance systems for buildings and spaces containing advanced components. One of the main design's parts is dedicated to intruder alarm system, access system, attendance and CCTV systems with the possibility of automatic motion tracking. Controlling and monitoring of particular subsystems is possible both locally and remotely from a computer via a web interface or by means of a software. The access to camera system from a mobile phone is also possible. IAS/ACS systems also enable controlling and transferring information about their state via SMS. The designed system was realized completely and its operating was demonstrated. The realization is described in detail including illustration of configuration of particular components. A security analysis and a possible future development of the project is summarized in the conclusion.
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.
Multi-Camera Scanner of Biometric Features of Human Finger
Trhoň, Adam ; Drahanský, Martin (referee) ; Strnadel, Josef (advisor)
This thesis describes a conceptual design of touchless fingerprint sensor and design, implementation and testing of its firmware, which is a composition of hardware implemented in VHDL and a program implemented in C. Result of this thesis can be used as the first step of building an industrial solution.
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.
Digital Text Steganography
Nodžák, Petr ; Nevoral, Jan (referee) ; Strnadel, Josef (advisor)
The goal of this bachelor project was to learn about digital text steganography, about methods for hiding the text, to implement my own or already existing methods and finally to compare acomplished results of these methods. This project introduces four methods (Zero distribution, semathics, syntax and Format based) which hide secret data into cover text, each of them by its own way. Research has found that semanthics method produces the best properties of stego text followed by Format based and Zero distribution, syntax method ended up worst. Based on the data found we can choose which method we will use.
Issue of Migrating from Single-Core to Multi-Core Implementation of Operating System
Matyáš, Jan ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This thesis discuss necessary changes needed in order to run MicroC/OS-II on multicore processor, mainly Zynq 7000 All Programmable SoC which uses two ARM Cortex-A9 cores. Problems that arise during this transition are also discussed.
