I²C-Unverträglichkeiten

-

hallo,

ich betreibe i²c-bus eines arduino uno vier geräte (lcd, led-display, temperatursensor, fm-radio). problem: das radio funktioniert nur, wenn das led-display nicht bus hängt. es gibt keinen adresskonflikt.
es ist sogar so, daß wenn ich das system ohne led-display starte und manuell später dazuschalte - dann laufen alle 4 busgeräte ohne probleme parallel.
der konflikt besteht nur zwischen diesen beiden geräten. im moment bin ich etwas ideenlos...

grüße
roland

damit wir ideen haben können, fehlt schaltplan, sketch und genaue liste der komponenten.
