Communication and control card for electron microscope
Robotka, Jan ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
The main aim of this thesis is to design a communication and control card for an electron microscope, eventually for other equipments of the company Delong Instruments a.s., which is dealing with its development and production. This card should replace existing communication card because of its low computational performance. Also, it should replace control and measure card manned with A/D and D/A converters. Thus, the new card will be providing not only the communication with a superior PC and other electronic systems, but also the control of other subsystems of the electron microscope, the determining of processional states and the measuring of internal physical quantities. At the beginning the requirements were determined and the main concept was made with the inclusion of the simple block diagram. It was very important to choose a suitable microcontroller, which will be an intelligence of the whole card and so it will be the most important component. The accent was set mainly on the sufficient computational performance, high modularity of its periphery, good vision of the future innovation and support and, of course, the price. The next requirement was the implementation of the Ethernet, which will be used for the communication between the card and the superior PC. The microcontroller which was chosen have the core architecture ARM Cortex-M3 and it is described in separate chapter. The next part of this thesis is dealing with the main communication standard of the card, which is the Ethernet. After the general description, the Ethernet was mainly discussed in context of the chosen microcontroller. The possibilities of the application of higher layer TCP/IP protocols were also discussed. Implied part of the thesis was the selection of other important components, especially A/D and D/A converters. Its characteristics will have a big effect on the characteristics of the card. In the last and the most important phase the electrical scheme was designed and it was described in detail. This scheme is the main result of this thesis and it is the main document for the future realization. Designed card will be able to process and control 16 differential analogue input signals, 16 differential analogue output signals, 8 digital inputs, 8 simple digital outputs and 4 digital outputs triggered by optocouplers. It will be able to communicate with the superior PC over the Ethernet with the maximum bit rate of 100 Mbit/s, with other electronic cards over the serial line UART through the optical fibers and with other internal and external equipments over the RS-485 and RS-232.

Digital voice communication network with status indication
Pobiecky, Michal ; Šilhavý, Pavel (referee) ; Krajsa, Ondřej (advisor)
The main focus in this diploma thesis is to analyse ARM microcontroller ATSAM3X8E, audio codec TLV320DAC3203 and CAN / RS485 bus for communication possibly used in device design. This device's purpose is to establish communicatio between elevator cabin and central control unit. Finally, there is design made for this communication device and measurement of CAN bus speed on H05VVH6 cable.

Digital I/O card with USB communication
Kořínek, Milan ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
The thesis deals with the design of digital I/O card with USB connectivity for Honeywell spol. s r.o. – HTS CZ o.z. company. The main objective is the delay elimination between reading the current state of the inputs and outputs setting which occurs on the actual used commercial card. Further initial analysis outlines possible solutions at the beginning of the work. One of chapters describes USB communication interface, including its com- munications protocol and USB driver implementation on the operating system Microsoft Windows. The digital card has four I/O ports consisting of eight lines. All ports have built-in protection against overcurrent and ESD protection. Digital isolator is used for USB. Power is supplied via USB, but it is optionally possible to connect an external power source. The last part of the thesis is focused on the card driver design.

Control of a model with CAN protocol
Procházka, Matěj ; Kříž, Vlastimil (referee) ; Hynčica, Ondřej (advisor)
This thesis focuses in the importance of technical text on the CAN protocol, the design of communication with robotic chassis. The first part contains general information about the CAN protocol and its settings, and a preview of what products I worked. The second part focuses on software robot. The next chapter describes the hardware of my work and the last chapter is devoted to experiments with the robot and the overall evaluation.
