Jeden z možných spôsobov je vypisovať<br /> po sériovej linke v pravidelných intervaloch holé data a tie potom uložiť ako <br /> maticu do Matlabu a tam nakresliť graf, priebeh, čo treba...<br /> <br /> Iná možnosť je použiť napr. program StampPlot, ktorý kreslí prichádzajúce data<br /> priamo ako graf, s výnimkou reťazcov, ktoré začínajú znakom &#039;!&#039;, tie považuje za<br /> konfiguračné príkazy. <br /> <br /> Download: [http://www.selmaware.com/stampplotlite/StampPlotLite_V17.zip StampPlotLite1.7]<br /> <br /> Príklad: [[AVR StampPlotExample.c]]<br /> Manual: [[Stamp Plot Manual]]<br /> <br /> <br /> <br /> === Úlohy ===<br /> <br /> <br /> # Nahrajte si knižnice pre prácu so sériovou linkou, preštudujte využitie knižnice &lt;stdio.h&gt; a demonštrujte.<br /> # Doplňte program o jednoduchý A/D prevod a zobrazte hodnotu z termistora na doske MiniMEXLE.<br /> # Overte prevod A-D prevodníka meraním vnútornej referencie 1,1 V<br /> # Upravte program pre A-D prevod tak, aby v pracoval autonómne s periódou vzorkovania 100ms. <br /> # Oboznámte sa s programom StampPlot a zobrazte časový priebeh teploty z termistora.<br /> # Vyhodnotením prechodového deja identifikujte veľkosť kondenzátora vo výstupnom filtri.<br /> <br /> <br /> <br /> === Download ===<br /> <br /> <br /> [[Obrázok:Icon_Terminal.png]] [http://braypp.googlepages.com/Terminal20080315.zip Terminal 1.9b]<br /> <br /> [[Obrázok:Icon_StampPlotLite.png]] [http://www.selmaware.com/stampplotlite/StampPlotLite_V17.zip StampPlot Lite 1.7]<br /> <br /> <br /> <br /> <br /> [[CAD_Riadiacich_syst%C3%A9mov#Cvi.C4.8Denia|Návrat na zoznam cvičení...]]<br /> <br /> [[Category:AVR]][[Category:MMP]]</div>
