hi folks,
Trying not to reinvent the wheel here (hoping this is a road someone else has already been down).
Has anyone successfully connected a Picaxe to a Humminbird 700 series GPS fishfinder?
If so, would you mind sharing what you've learned?
My yak already has a 20M2 controlling the trolling motor speed & steering, but I would like to extract the NMEA data from the Humminbird to have the yak automatically follow a heading (crossing big water in a straight line) & be able to use waypoints (set on the Picaxe display) to travel from point to point.
Once I get the position & heading data, the Picaxe should be able to bump the left/right steering outputs to track a course.
Here's a little info:
