Digital controlled resistor
Sedlář, Petr ; Petržela, Jiří (referee) ; Šotner, Roman (advisor)
This master´s thesis deals with the design of the control circuits for digital potentiometers and their application in analog systems. Digital potentiometers are three-terminal resistors with an adjustable center connection. The digital potentiomneters enable to drive logic gates, LED drivers, LCD drivers, analog switches etc. Controlling of these mentioned devices is possible by the I2C 2- wire serial bus (invented by Philips). The digital potentiometers are used to control of the primary parameters like cut-off frequency and quality factor in the state variable filter and cut-off frequency in a passive filter. Both filters are simulated in PSpice and then compared with the measured results. Next parts of this master's thesis are a computer program and a exemplary protocol.

Control system of mouth-organ
Trukhina, Irina ; Franek, Lešek (referee) ; Bradáč, Zdeněk (advisor)
The master’s thesis describes development of control system for automatic mouth-organ. The process of development is divided into three parts: a concept of control system, design of hardware parts and development of software parts. Controlled device, system requirements and general design of the hardware and software components are described in the concept of control system. The detailed hardware design includes next processes: electronic component selection, printed circuit board design, assembly and debugging. The result of this chapter is electronic system, which function correctly. The aim of the last chapter is to specify and explain development of software parts of control system. Installation of required software and important aspects of control software and user interface development are described in this chapter. The goal of the thesis is to create a control system, which will function correctly and reliably.

Universal Microcontroller Unit
Kulenda, Vít ; Hynčica, Ondřej (referee) ; Kučera, Pavel (advisor)
Master’s thesis contains description parameters of microcontroller ATMEGA644P, also contains differences between older and newer version of microcontrollers ATMEGA644 and ATMEGA644PA. Inside structure of microcontroller, memories and peripherals are described here. The construction of the universal microcontroller unit is main target of this thesis. The unit contains supply, A/D converter, current loop, communication interfaces, temperature sensor, accelerometer and other. The unit collects and saves data, communicates by interfaces and manages other functions. Using devices and circuits are described in this thesis. Development of software for microcontroller(firmware) are positioned to last part of this thesis. This software control functions of all parts positioned on the unit.

Inteligent control unit for hot water heating
Nedoma, Pravoslav ; Pavlík, Michal (referee) ; Havlíček, Tomáš (advisor)
The target of the project is to design the control unit of the hot water heating with the dynamic run depending on the building heating loss, including possibility of adjusting of room´s temperatures individually by user. System is driven by microprocessors and uses digital temperature sensors and electronically controlled valves. All information and datas are displayed on the LCD display panel and whole unit can be easily connected to the PC via the USB port or Bluetooth.
