Seatalk1 to NMEA0183 with Arduino
#11
FYI sk server NMEA 0183 parser can decode STALK sentences that carry the raw Seatalk data, so you don’t need to do any per sentence conversions if you have a sk server already running.

Do you have any code you'd like to share? I'm still struggling with this.

espsoftwareserial works well for me on my web based autopilot controller. Set up 8bit Mark/space parity. Parity bit will be mark for command bytes. Call readParity to check.

Could you share some of your code ?

I have put the code onto github (I hope - I'm new to this app)[/url]

It asumes that your Seatalk 1 interface inverts the signal otherwise change true to false in the software serial initialization

mySerial.begin(4800, SWSERIAL_8S1, RX_IN, TX_OUT, true, 256, 256);

Processing Seatalk takes place in the readST function.
