I have an autopilot project involving a Raymarine St 1000+, and Arduino, and a Raspberry Pi.
Open CPN (or equilavent) will be used to send navigation commands through the Pi, to the Arduino, and onto the Autopilot.
I have purchased a Seatalk converter, that I hope to install on the i/o pins of the Pi. Otherwise, I will use NMEA strings from the Pi to control the autopilot. There is one major hurdle in the way of this project: the waypoint advance feature that requires the operator to press two buttons on the autopilot in order to advance from one waypoint to the next. The reason this feature is a problem for me is that I won't be on the boat, it's a drone. I know there are safety concerns--but all are being considered and taken very seriously.
Does anyone out there have code, or suggestions for interfacing this setup? Ideally, I would like to provide all of the navigation strings required for the drone to complete routes: waypoint to waypoint, without the interruption of the Raymarine st1000+ waypoint advance feature. Perhaps if I only provide the unit with the minimum message required it will not be so temperamental.
Any and all recommendations are greatly appreciated.
