The communication between the padle wheel and the log is probably very basic : the pulses of the padle contact ! One way to check that is to use an analog mulimeter like this one
At low speed you should see the beat of the needle at the rytm of the pable revolutions...
Then you may have 2 possibilities :
- connect the signal (with great precautions -level adaptation) to a GPIO pin, and code ...
- go for an airmar DST800 which offers a NMEA output - both NMEA 0183 and NMEA 2000 versions exists ...
If you are lucky, as a bonus, you may be able to connect its paddle signal to your existing log (to be checked in the doc, level adaptation may be necessary) ...
