20.500.12556/RUL-73151 Razvoj bioimpedančnega merilnika na osnovi mikrokontrolerja Development of a bioimpedance measurements device based on a microcontroller Diplomska naloga se nanaša na razvoj, izdelavo in testiranje elektronskega vezja, namenjenega nadgradnji merilnika za potrebe merjenja (bio)impedance. Uporabo v mikrokontroler vgrajenega analogno-digitalnega in digitalno-analognega pretvornika sem nadomestil z zunanjimi zmogljivejšimi integriranimi vezji. Tiskano vezje sem zasnoval in izdelal s programskim paketom Altium Designer ter ga povezal z razvojno ploščo mbed NXP LPC1768, ki vsebuje mikrokontroler. S programskim jezikom C++ sem v prevajalniku, ki je za potrebe programiranja razvojne plošče dostopen na spletu, vzpostavil serijsko komunikacijo z zunanjimi integriranimi vezji. Nato sem izdelal testno vezje ter preizkusil delovanje končnega izdelka. V diplomskem delu je opisana zgradba, delovanje ter konfiguracija uporabljenih integriranih vezij ter realizacija programske opreme. Podani so tudi rezultati meritev, ki sem jih naredil na testnem vezju. The tesis describes the development and testing the prototype of electronic circuit, which is designed to upgrade existing bioimpedance device (BIA). The current design is based on usage of a microcontroller with integrated AD/DA converters, while the upgrade include the use of faster and more accurate AD/DA converters. Printed circuit board (PCB) was designed in Altium Designer software package and connected with mbed NXP LPC1768 development board. Serial communication between integrated circuits and microcontroller was designed in C++ compiler, which is online and intended to programming development board. Then I prepared a test circuit and tested the functionality of the final product. The thesis describes structure, operation and configuration of used integrated circuits and realisation of software. There are also measurement results, which I have done on the test circuit. elektronsko vezje integrirano vezje AD in DA pretvornik Altium Designer razvojna plošča mikrokontroler C++ serijska komunikacija testno vezje electronic circuits integrated circuits AD/DA converter Altium Designer development board microcontroller C++ serial communication test circuit true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2015-10-26 13:45:05 2015-10-26 13:45:06 2022-08-01 17:12:40 0000-00-00 00:00:00 2015 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 30342 Obid_Jure_-_Razvoj_bioimpedancnega_merilnika_na_osnovi_mikrokontrolerja.pdf Obid_Jure_-_Razvoj_bioimpedancnega_merilnika_na_osnovi_mikrokontrolerja.pdf 1 4CDA7A620BA8D2BFB3735FA7A8F27216 83fc98142fad511fa71c0f4b5ea9dfbbefef4d4214bc6625dc03ff280f58c6da 628ebb64-a1ad-11eb-a523-00155dcfd717 20.500.12556/rul/0f3989a1-4cb0-4268-89ec-7e0761ece526 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=73188 Fakulteta za elektrotehniko 0 0 0
