Wenn die Spannung potentialfrei wäre, könnte man das ganze einfach per ADC messen. Da aber

Bei meiner Schaltung werden nur A16 und A17 benötigt und daher wird auch nichts multiplexed. Vom µC wird nur minimale "Rechenleistung" für die Bildausgabe verlangt und der µC interne Bildspeicher bietet optimale Zugriffszeiten.

of time to spare. But there are times when interrupts are the simplest way to do two or more things at once. How interrupts work. For the examples here, we’re going to talk about the 16C84. The same principles apply to the other interrupt- capable PICs, such as the 16C71 and 16C64, but registers and interrupt
