I am having some troubles wrapping my mind around all things auto pilot.
What I would like to understand is how to duplicate the +/- 10 degree and +/- 1 degree functionality of the control buttons that are on my Raymarine ST4000+.
It would seem to me that all I need to do is to send some kind of a NMEA 0183 sentence to the E80 display that would then translate the sentence onto it's attached Seatalk bus which then reaches the autopilot and magic happens.
At this point I need a hint as to either what the magic NMEA sentence(s) is/are or a pointer to a URL where I might find documentation that could lead me to that magic sentence.
Somewhat related, currently my AIS feeds data via NMEA 0183 to the E80 chart plotter. I will need to feed that data into openPlotter and from there it needs to go back out to the chartplotter via it's NMEA 0183 input. I can then add the magic autopilot sentences to the stream and presto .... I hope. Has anyone written up how to combine the two streams (AIS and autopilot) ? It would be great if I could find something that shows me how to go about doing this.
