Communication Adaptor for Data Acquisition System Hardware and Software Design
Kašpar, Petr ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
The aim of this bachelor thesis is to create adaptor with microcontroller for data acgusition system. Function of the device is to receive serial asynchronous string of ASCII characters which was send from ultrasonic thickness gauge. Baud rate of transmittion is 2400Bd. Transmittion is realized according to RS-232 standard. Part of the string contains numeric information about value which was measured by thickness gauge. This numeric information is in microcontroller multiplied with corrective constant and decimal point in result is placed to right position. Corrective constant is stored in EEPROM memory. After that adaptor transsmits data to superior system in format of serial asynchronous string of ASCII with baud rate 9600Bd. Thesis describes service code for microcontroller in Assembler language and hardware construction of device.

Analog-Digital Converter Unit with Data Output by Serial Line
Lecián, Petr ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
This work is about measuring voltage and manipulating with this way obtained data. Manipulating system is in this case 16-bit microcontroler PIC by Microchip, that transforms input data to output using known non-linear trace. Microcontroler has been programed in the symbolic adress language. I had to create a unit that would be a part of the special device for indirect measuring non-electric quantity. Output data should be sent to the superior system by serial bus RS-232 for a next use.

Control of graphic OLED display with Atmel microcontroller
Bartošík, Vladislav ; Lattenberg, Ivo (referee) ; Hanák, Pavel (advisor)
This Master's thesis deals with design and a realisation of a device controlling an OLED display, Densitron DD-25664-1A. This display has a resolution of 256 x 64 pixels and allows displaying of 4-bit grayscale. The proposed utility software implements the initialization and termination functions, two sets of fonts { Latin and Greek letters and functions for rendering graphics and text. The result of the project is a device with the controlling software.

Dynamic reconfiguration with Atmel FPSLIC
Jančík, Martin ; Hanák, Pavel (referee) ; Fedra, Zbyněk (advisor)
This study describes the platform Atmel FPSLIC, which is created by means of the logic arrays FPGA and the micro-sequencer controller AVR. The developmental kit STK594 is described here as well, with its programming possibilities, as for the logic arrays FPGA, as for the micro-sequencers AVR. Also the separate circuit AT94K is described there. This circuit can be programmed by the language VHDL (the field FPGA), or by means of the assembler and language C for the micro-sequencer. All this can be integrated into the one output file by means of program System Designer, comprising a set of software tools for given programming languages and for generation of the whole circuit. Furthermore, the study describes a simple application for the both platform parts. Also the description of the dynamic reconfiguration of the circuit gate part is included.

Communication devices over GSM/GPRS
Prečan, David ; Růčka, Lukáš (referee) ; Herman, Ivo (advisor)
This master thesis deals with a data remote transmission by means of SMS and GPRS technology. The overview of current solutions is presented and then a remote temperature measurement and a data transmission employing a communication module GSM/GPRS TM1 through GSM network using GPRS technology is described. As a response to an impulse, the communication module sends SMS. The technical solution is described in details including HW and SW design of the data transfer and processing equipment using a ATmega 162 microprocessor. This equipment communicates with a server (PC), which displays the measured temperature. A prototype which was used for a validation of the design is also described.

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.

Microcontrollers programming possibilities
Šubrt, Stanislav ; Kovář, Jiří (referee) ; Houška, Pavel (advisor)
This work is focused on inner structure and programming possibilities of microcontrollers. The work goal is to describe inner structure of microcontrollers from the programmer’s point of view, find out advantages and disadvantages of their programming in Assembly language, C language and higher-level languages. Code portability between different microcontrollers’ families and architectures is discussed further.

Design and realization of teaching instrument
Pučegl, Pavel ; Krček, Petr (referee) ; Marada, Tomáš (advisor)
Gradual wear and growing dissatisfaction with current panels for purposes of teaching the course „Logical control and programmable controllers“ has lead the Institute of Automation and Computer Science at Brno University of Technology to a decision to establish a new educational tool „LOGIK“. The tool is intended to facilitate practical verification of knowledge gained by students during this course. Students will have access to this device and will carry out various practical projects concerning combinational and sequential circuits. The general objective of this thesis is to design and subsequently construct this educational device so that is could be fully utilized during the course in near future.
