// Convert fast heading data from NMEA 0183 to NMEA 2000

#include <Arduino>
#include <NMEA2000_CAN>
#include <N2kMessages>
#include <TinyGPS>

TinyGPSPlus gps;
TinyGPSCustom heading(gps, "HCHDG", 1); // $HCHDG sentence, 1st element

void setup() {
Serial2.begin(9600);

NMEA2000.SetProductInformation("00000001", 100,"Heading converter", "1.0.0.11 (2016-04-13)", "1.0.0.0 (2016-04-13)");

}

while (Serial2.available() > 0)
gps.encode(Serial2.read());

Najednostavniji bi bio ovaj

240-33 ohm i najčešći 0-190
ovi prodaju 400-500€ Nevjerovatno ali i kinezi slično

Svi novi brodovi su NMEA 2000. ali doplata je do jaja par tisuća €
