Retargeting of the assembler language compiler
Navrátil, Jan ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This bachelor thesis describes a design and implementation of modification of retargetable compiler Flat Assembler G that provides a translation of assembly language for HCS08 microprocessor family. It describes current solutions in the design of assembly language compilers, existing retargetable compilers and their differences from Flat Assembler G. Furthermore, it shows process that can generate binary output in selected format with the compiler. Last part of this thesis is dedicated to testing of the correctness of the implementation and demonstration of the correctness on a real hardware.

Wireless Signal Transmission of DMX512 Interface
Polóni, Pavol ; Jaroš, Jiří (referee) ; Šimek, Václav (advisor)
Master's thesis deals with design and implementation of a system for wireless transmission of DMX signal 512, which is primarily designed for the management of lighting effects. Its electrical specification is based on the EIA485 standard. Text of the work describes the design stage. First is the issue of implied actual protocol DMX 512 or EIA485. Next sign on selecting a suitable architecture for wireless transmission, management and compilation of the block diagrams. Describes the operation of the component selection and circuit implementation of the scheme, which is using the DPS Eagle compiled. In conclusion, this work is to evaluate the results of the proposed system and showing the way to its further development so that it can be realistically implemented in practice.

Memory-Card Reader
Rumplík, Michal ; Mikušek, Petr (referee) ; Strnadel, Josef (advisor)
This work deals with problems of SD memory card reader and its working principles. I have focused in my bachelor's thesis on proposition and construction of memory-card reader. This memory-card reader is able to store and read ASCII signs. The hardware was proposed for serial interface communication and it is geared by microcontroller MC9S08QG8.

Laboratory assignment for HCS 08 microcontrollers
Bilík, Jan ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
The goal of my bachelor thesis is getting acquainted with serial buses I2C, SPI and 1-Wire and their implementation in communication between microcontroller NXP MC9S08LH64, temperature sensor, real-time clock circuit and shift register. The thesis also focuses on hardware connection with necessary circuits and behaviour of software functions used during data exchange.

Rotational Display
Konečný, Ondřej ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This thesis describes the process of hardware and software development of a rotational display, that uses accelerometer for acquisition of placement data. It explains the principle of operation of the rotational display and of the components that were used. There are discussed various ways of accelerometer usage for these purposes and there is also explained the solution of the problem of timing for the purposes of displaying. In the end the thesis summarizes the results of the development process and outlines possible future development.

Terminal for remote visualization and control conditions in the house
Szalay, Patrik ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This diploma thesis deals with the modification of an existing device for controlling the heating system of the house. The original proposal builds on my bachelor thesis Terminal for visualization and control conditions in a house. Adjustments are based on the findings of the test operation and the deficiencies found in everyday operations. Here, the emphasis is on simple design, low acquisition cost and durability of the resulting device. Newly designed wireless units will replace the original wired sensors, as well as the control unit of the existing device based on the prototype system will be replaced with a new wireless central unit. The alphanumeric display with control buttons will remain as the control panel of this unit. The wireless central unit is connected via a serial communication interface to the visualization and control unit, which extends the offered options of the heating control system.

LCD displays' library
Lutera, Ondřej ; Valach, Soběslav (referee) ; Macho, Tomáš (advisor)
This bachelor's thesis deals with the design and implementation of graphics objects Text Box, List Box, Progress Bar and Edit Box to the library D4D by Freescale for controlling LCD displays. Development was performed using the development kit DEMOQE128 with MCF51QE128 ColdFire processor by Freescale.

DMA Support for HCS08 Microcontrollers Family
Novosád, Adrián ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
Embedded systems are dedicated to perform specific tasks, so design engineers can optimize them to reduce the size and cost of the product and increase the reliability and performance. However, result of these optimizations is that some architectures may lack commonly used technologies such as direct memory access (DMA). We may encounter with this situation in family of microcontrollers HCS08. The main theme of this work is to describe a design of DMA controller that can be added into the family of microcontrollers HCS08.
