Die Funkübertragung ist etwas komplizierter als die kabelgebundene Kommunikation, weil man nie weiß, welche Funksignale in der Luft vorhanden sind. Daher ist es wichtig, wie das übertragene Signal kodiert ist. Und hier gibt es viele Möglichkeiten: die Hardware-Kodierung wie USART verwenden oder eine eigene auf Basis einer der vielen Kodierungsverfahren wie NRZ, Manchester usw. schreiben. In meinem Beispiel habe ich das AVR-USART-Modul verwendet, um Datenpakete zu bilden. Hardware-Encoder lösen viele Probleme wie Synchronisation, Start und Stopp sowie verschiedene Signalprüfungen. Aber solange ich mich damit beschäftigte, konnte man sich nicht auf ein reines USART-Signal verlassen.
