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

Krass, wie hast du die 71,7 Hz berechnet?
Ich hab deinen Vorschlag durchgearbeitet, komm jetzt auf 71,6 Hz.

Man gut, dass man als Programmierer sowas automatisieren kann

Ich hab das Gefühl wir kommen gut voran

Aktueller Stand:

Code:

/*
 *B0-CP
 *B1-LOAD
 *B2-FRAME
 *
 *C0-D0
 *C1-D1
 *C2-D2
 *C3-D3
 *
 *Mega8 @ 16MHz
 */
