Gibt es noch Optimierungspotential? (Mega8 an 320x240 GLCD Textmodus)

So mag ich das, wenn da passende Grüße kommen

Zitat von MisterMou

Das mit dem Entrollen hatte ich gestern schon mal probiert, dabei wurde "k" durch Konstanten ersetzt. Das Ergebnis war langsamer o.O

Langsamer muss es nicht zwingend sein, mit Konstanten wird's aber nix. Nachdem der Compiler in mancher Beziehung extrem stur ist, hab' ich's nochmal anders versucht.
Wenn's geht, was ich doch hoffe, zumindest die Simulation sah gut aus, so wären das 107Hz@16MHz. Optimierung -Os.
