trotz I2Cslave Library zeigt Bascom fehler an

[Zeroeightfifteen]

Doch da war ein Beispielprogramm dabei, doch da zeigt Bascom mir auch nur fehler an.

Hi,
schau mal unter:
https://www.roboternetz.de/phpBB2/vi...3c667e62a79bba
da steht ja ein Beispiel zum Slave.
Die Slave LIB braucht man für die ganzen Tinys die ja kein hardware TWI haben. Der M8 Ist da irgendwie eine Ausnahme.
Der M8 hat ja Hardware TWI, geht aber auch mit der Slave LIB.
Die größeren Megas gehen wohl dann nur mit dem Hardware TWI als Slave.
