Summary[edit]
DescriptionTakt aperiodisch.png |
Deutsch: I²C-Übertragung (Ausschnitt: Startbedingung und Adressierung), der per Bitbanging steuernde Prozessor behandelt nach dem dritten Bit einen Interrupt.
Unten das aperiodische Taktsignal bei einer I²C-Übertragung (zu sehen ist der Beginn mit der Startbedingung (markiert mit einem grünen Punkt) und der Adressierung inkl. Acknowledge; die obere Wellenform stellt das Datensignal dar, die untere das Taktsignal). Das Taktsignal besteht nur aus einer passenden Anzahl von Taktzyklen. Das Übertragungsprotokoll wird durch Software gesteuert (Bitbanging); der steuernde Prozessor behandelt hier im Beispiel einen zufällig nach dem dritten Bit aufgetretenen Interrupt, wodurch sich eine Verzögerung der Übertragung (hier um etwa 70 µs) ergibt. Da Daten- und Taktsignal dennoch synchron zueinander bleiben, handelt es sich um ein vollkommen legitimes und gültiges I²C-Signal. English: I²C transmission (excerpt: start condition and adressing), the via bit banging controlling processor services an interrupt after the third bit. |
