[moritzxbe]

hi i have tried your code and get the following error

avrdude: verification error, first mismatch at byte 0x7800
0xff != 0x61
avrdude: verification error; content mismatch

what can I do? Many thanks in advance!

I've got the same message when uploading to arduino (version 2.8.3-RC)

Uploads fine for me with ArdBir_2_8_3RC8 and 1.6.5 environment on windows. Maybe verify that you can upload test code (such as the blink example code in File->Examples->Basics ).

Also check that you're compiling against the same board that you're using, as this can cause mismatch errors.
