Thank you very much for your help!
What I did:
- connected the port expander (adafruit servo driver) with my GT2560 Board
- uploaded the example-code for adafruit servo-driver on it
-> Output works, there is a +5V signal on the PWM-Pin of Output #0
Then I uploaded the marlin code with
Next I used the upper code you posted and sent it line by line in the terminal.
But with Marlin I don't get an output on PWM-Pin #0 ....
Do you habe any further idea?
