I have been using a windows computer software autopilot
that I found.
It only requires a com port , relay board and GPS
It reads either $GPRMC or $GPVTG Baud 4800 and compares it to the set point then calculates an output that triggers Serial
port DTR Pin 4 (steer to Port) or RTS Pin 7 (Steer to Starboard).
A Relay board is needed to amplify the com port outputs to drive the autopilot Motor
It's tunable with Delays , Gain , Drive Time and PID loop.
I've attached the program zip and manual.
I would like someone with the necessary skills to convert it into an OpenCpn plugin
The main work
1. Decomplile the program (Possibly compiled in Liberty Basic)
2. Allow the use of 38400 Baud (Set to 4800 only)
3. Include activated route
to be used as course set point
4. Build as a plugin
for easy cross platform use
