Low-power wireless sensor node
Pobiecky, Michal ; Koton, Jaroslav (oponent) ; Krajsa, Ondřej (vedoucí práce)
The main purpose od this thesis is to design wireless sensor node with emphasis on low power consumption. This device is firstly made of microcontroller Atmel ATmega328P and for transferring measured data XBee 802.15.4 or transceiver nRF24L01 is used. Subsequently there is a design with Atmel ATmega256RFR2 with integrated wireless part and Lightweight Mesh protocol. Special attention is given to sleep modes and lowering power consumption. For ATmega328P the measurement of these power modes is done.

Digital voice communication network with status indication
Pobiecky, Michal ; Šilhavý, Pavel (oponent) ; Krajsa, Ondřej (vedoucí práce)
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.
