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.

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.

Design and Implementation of a Software UART for Microcontrollers from HC08 Family
Kučera, Pavel ; Vašíček, Zdeněk (referee) ; Strnadel, Josef (advisor)
Bachelor's thesis deals with problematics of serial communication, specially of serial asynchronous communication of microcontrollers from HC08 family. Thesis includes analysis of SCI module, which provides serial asynchronous communication of microcontrollers. On a basis of the analysis the software solution of UART (sUART) for microcontrollers from HC08 family, which have no SCI module, was created. SUART interface was successfully tested by communication with a computer using RS-232 interface as well as by communication between several microcontrollers.

Wireless Barcode Reader
Novák, Jan ; Vašíček, Zdeněk (referee) ; Strnadel, Josef (advisor)
This bachelor´s thesis is about barcode symbologies and wireless communication. Goal of this work was to design and construct wireless barcode reader. For communication are used OEM modules Aurel Wireless, working in SRD 868 MHz band. Receiver and transmitter are controlled by microcontroller HC908QY4 .

Design and Implementation of Real-Time Operating System Kernels Running on HC08
Bednář, Jan ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The project is aimed at testing the kernels of real-time OS within the HC08 platform. The RM, EDF and polled loop mechanisms are being compared as well as freely available FreeRSTOS and QP systems. The project also incorporates descriptions of techniques used in the development, obtaining and the implementation of test environments. The evaluation is based on the tests made within the HC08 platform and the knowledge gained from the programming for every individual type of real-time OS.

Patient data trasfer over GSM
Pavliš, Jaroslav ; Dlouhý, Jiří (referee) ; Švrček, Martin (advisor)
This diploma thesis is concerned with possibilities of patient data transfer from a pacemaker or implantable cardioverter-defibrillator to physician over GSM. Theoretical part describes options of data transfer in GSM networks, data appropriate for sending and a structure of message is proposed. A device, that is able to send medical data in a form of SMS messages is designed and constructed. The device uses a Freescale MC68HC908GP32 microcontroller, character display with a Hitachi HD44780 controller and a cell phone Sony CMD-J70. The program for microcontroller is written in assembler for HC08. For tabular view of received messages, an application software for PC was created.
