Hallo again,
finaly i got it working. Give me a few days to clean up my code. I'll then post it here.
To describe the project: The SSI is needed to get the absolute position of an rotary absolute enconder, then transfere the Position to MAX/MSP/Jitter, and play a video synchron to the read Position of the encoder.
Right now i'm only hassling with the HF-electronics, but in principle it works right now.
Thanks a lot,
Stephan
