Realizace vizualizace dat pomocí jednočipových mikroprocesorů

Abstract

This diploma thesis deals with design and realisation of communication interface for vital function data receiving and visualisation. The control unit for the communication interface is AVR ATmega644P. The data are displayed by color STN LCD with integrated PCF8833 controller and driver. The user communication interface is realised by user menu displayed on LCD and by keyboard buttons of the Nokia 6610 matrix keyboard. User can display actual measuring of EKG and pletysmograph curves. Values of temporal measured pressure, weight, temperature, SpO2 and room ID are stored in memory for later browsing and evaluation using the trend graph tool. It is possible to display the position of monitored person in defined territory. In the external data FLASH memory, connected to the μC, are stored the image data, user interface icons, measured values, data image of monitored area, settings. The FLASH memory is programmable by user interface through the USART. Communication between μC, LCD driver and external FLASH is realised by SPI. Data receiving is realised by TWI (I2C). The diploma thesis is a part of the CERBERUS II project.
