Funkmodule und Atmels

**Knickohr** · 07.07.2007, 12:17

Hallo

Es funktioniert !!! \

/ \

/

Habe die Dinger zum Laufen gebracht. Ich habe einfach die Baudrate auf 1200 Baud gesetzt und seit dem kommts auch an. Zwar ist immer noch des letzte übertragene Zeichen Müll, aber das ist eine Kleinigkeit. Seltsamerweise setzt die erste Übertragung auch nicht an der ersten Stelle auf, sondern irgendwo mittendrin. Es sind immer ein paar Blanks am Anfang. Naja, halt beim ersten Mal senden.

OK, hab Programm noch ein wenig angepaßt.

@Wigbert:
Die 1 Sekunde Warten war offensichtlich kein Problem. Ja OK, wenn während der Zeit was gesendet wurde gings natürlich ins Nirwana.

Ist da eigentlich ein Schreibfehler ?

Das rot markierte meine ich. Das würde zumindest bei mir den Fehler mit der herunter gesetzten Baudrate erklären.
