Enigma auf dem µC

[Che Guevara]

Also ich teste gerade an der Hardware, und bei mir funktionierts nicht immer! Schon der zweite "zufällig" generierte Text "16:9:9:3" wird zu "16:9:15:18" ! Ich weiß aber nicht, worans liegt...

Mittlerweile habe ich über 5000 Durchläufe ohne auch nur einen Fehler

Auch auf echter HW ?

ABER: Wo ist der Unterschied?

Kann ich jetzt auch nicht sagen...

[Che Guevara]

Ja, auf echter Hardware ATMEGA32 aufm RN-Control. Funktioniert einwandfrei Nur mein Code funktioniert nicht, obwohls fast der gleiche ist?! ...

Gruß
Chris

[MagicWSmoke]

... obwohls fast der gleiche ist?! ...

Mit kleinen Ausnahmen:

Else
   Reflektor_in = Reflektor_in - 1
   If Reflektor_in = 0 Then Reflektor = 26
End If
Reflektor = Reflektor_in
End Function

Oh, jetzt sehe ich es auch... Danke!
Dann werde ich jetzt mal am Projekt weiterbasteln

Vielen Dank & Gruß
