Ik wil graag een applicatie starten die ik gevonden heb via het irnet. Maar als ik dit met Jcreator run krijg ik alleen het bericht "Found port: COM4" en geen JFrame of grafiek in beeld. Kan iemand me hiermee helpen?

Code:

import org.jfree.chart.plot.PlotOrientation;

bedankt voor je bericht, ik ben nog bezig want ik krijg nog geen data op me poort in hyperterminal misschien dat het daar ook wel aan ligt. Maar volgens de makers moet ik zowieso eigenlijk een scherm krijgen met een lege grafiek.
 
ik krijg nu me data in hyperterminal maar java werkt nog niet, zoals ik al eerder zei ik moet zowieso een scherm zien. Kan het uit maken dan ik Jcreator gebruikt en hun Jbuilder?
 
problem is solved, topic closed. The problem was that I expected live graphs and the code is writen to collect data and after a number of seconds display
it. Also there where some hardware connection and firmware mistakes.

Klik om te vergroten...

En nu de Nederlandse vertaling graag. Helpmij is en blijft een Nederlands forum.;)
 
wie ken d'r nou geen engels :|

Nouja voor de dummies dan maar:
Topic kan gesloten worden want het probleem is opgelost. Ik verwachte live grafieken terwijl de code geschreven is om data te verzamellen en na een bepaalde tijd dat in grafieken te tonen. Er waren ook wat hardware foutjes en firmware fouten in de MCU mbt de UART
 
Heel veel mensen kennen geen engels...
En dan is en blijft het nog altijd een nederlands forum. Dus nederlands is de voertaal.
