The aim of this master’s thesis was the design RGB LED display with Ethernet interface. I created a display module, controlled by a microcontroller ATmega 2560-16AU. These modules can be connected via a serial RS485 standard. Ethernet connection is made via plug-in interface that uses the programmable module Rabbit RCM 3200. I documented a proposal. I tested designed device.

This thesis describes the design and subsequent construction of a board computer for a motorbike, using a GPS module. Vehicle speed, distance travelled and the motor's rotations (RPM) are among the basic elements that are measured and shown. Furthermore, the mechanism allows one to measure and show the average consumption, the temperature of the surrounding environment as well as the motor's temperature, battery voltage, current time, and, with the help of the GPS module, the current GPS location of the vehicle, including altitude. The vehicle's entire journey can be saved to the memory card for further processing in a PC.

Thesis deals with electronic ignition for a two-cylinder two-stroke engines. In the thesis is described the existing ignition system. In the thesis are described measurement options of the position ot the engine crankshaft. The ignition system is designed mainly for motor JAWA, CZ and motor Trabant. The design is focused on reliability of entire circuit. The main advantage of the entire proposed design is possibility to adjustable ignition curve, depending on several external parameters such as speed or temperature of the engine. The proposed ignition has been tested in vehicle Velorex.

The main components of the system for embroidery sewing machine is (Veritas 8014/35-2) and pointing devices. The machine automatically entered embroidered patterns, it is necessary to construct a pointing device and its control. To drive the pointing device used two stepper motors, the control circuit to cater to the ATmega128. Communication between PC and ATmega128 provides converter FT232.

This diploma thesis deals with the design, construction and programming of universal modular system of timekeeping for children´s outdoor sports games. The basis of this system are single-chip AVR microcontrollers Atmel ATmega 32 and ATmega 328. Data transmission between the modules is realized by a wireless serial port HC-12th. The system is applicable to multiple types of competitions with different types of sensors for time measuring, and it is independent of the continuous supply of electricity.

The aim of the study was to design, build and experimentally verify a programmable thermostat. The main control unit of the thermostat is an ATmega168 microcontroller which communicates via I2C bus with remote MAX6615 chips. They are used to measure temperature with a set of thermistors and control the flow of the hot water in the heating system. This work deals with issues of remote control through the I2C bus, servomotor steering, precision temperature measurement and describes the inner workings of the system. The next chapter includes a proposal for possible extension of the system. The last part contains the manual of the control menu structure and a brief description of the software.

This paper describes complete design of timer for RC models. Described timer has three PWM outputs. With these outputs it is possible to connect two independent servo-motors and engine controller. 1 signal. The whole is controlled by 8-bit microprocessor. The time records are stored in external EEPROM, that can be programmed using I2C. Paper further discuss design of programming, which can be easily programmed the memory of EEPROM by the PC or smartphone. The goal of this paper is to design and build high quality RC timer with accessories.

This thesis focuses on problematics of DAW controllers for sound production software. In this thesis is analysed Mackie Control protocol, one of used communication protocols. There is also an overview of MIDI messages, because Mackie Control protocol is based on MIDI protocol. The thesis contains two own DAW controller designs. First one is based on Mackie Control protocol, second one is based on Generic Remote which offers better customization.

The goal of diploma thesis is design of programmable control system. This system can be used for regulation of basic parameters in an aquarium. Primary parameters for selection of this device are the price and the easy realization of final device. In first step there are selected parameters, which are needed to control. In second step there is described which kind of sensors can be used for measuring of selected parameters and suitable regulation of necessary parameters. The device is supposed to communicate with PC by USB and this communication is going to be compatible with an old RS-232. Device must be completed with hardware design. Device will be in principle system with real time, that is the reason why device will contain microcomputer. A microcomputer must communicate with other integrated circuit in the device and it supposes to communicate with PC. In specific chapter it will be described, how many different kinds of communication it is possible. For microcontroller it is necessary to create a program, which can figure the measured parameters and it also allows setting up the way how parameters can be regulated. Measured parameters are supposed to storage in the specific memory for the later interpretation. The completely device must be put into a case, which is calculating with a damp place. There must be created a host application for PC. This application suppose to detect if device is connected, figure measured parameters and also allows to set up the way, how to regulate the parameters and display the storages parameters. The application is suppose to run on the operation system created by Microsoft (Windows XP and Windows Vista or later). Diploma thesis contains a problem of the analysis which parameters may be controlled and the way how it can be controlled. There will be selected the sensors, which are suppose to measure and there will be described the basic data transfer and the specifications. It will also contain description of the hardware and software implementation of the device and possibilities of the user’s settings. There will be described the host application and its possibilities. Finally there will be described a functionality of the device and the host application. It will be also imagined some system upgrades for future.

The thesis focuses on consideration of possible ways how to realize multi-state modulators for a laboratory instrument. This instrument will illustrate signals, which partake on generation QAM modulation. The design of the laboratory instrument includes theoretic schemata and the execution of a prototype. There are theoretical facts of multi-state signals and multi-state modulations in this thesis. A simple block diagram of the laboratory instrument is made by the theory of creating quadrature amplitude modulation. For each block there are made several schemata, which are compiled to the global scheme. A printed circuit board and the structure items are made by the aid of the global scheme. The next part is devoted to a software facility for a used microprocessor, which ensures the whole function of the laboratory instrument. The final section deals with measuring, which checks the function of the modulator and the right setting coder’s constellation diagrams.
