Ich habe hier dieses Programm. Das ganze ist in einer Hardware eingebunden. Nur nach einiger Zeit die der Chip läuft, beginnt das Programm von vorn. (es wird print start ausgelöst)
Man kann sich das so vorstellen:
-> Chip bekommt strom und läuft los
-> Print "start"
-> Warte einige Zeit
-> Print "start"
...
Warum ist das so?
