Ideas for a low level controller / interface. Could be ALL discrete logic hardware! Probably PIC's
These are signals from the dish.
Signals from the dispatcher (PC application)
Feedback - "What are we telling the dish to do now?"
CLA - combinatorial logic array
The serialization doesn't show double buffering, or any CRC error detection.
The safety CLA contains comparitors to ensure the dish axes are well clear of the end stops.
