NMEA2000-SeatalkNG-AlarmBuzzer

This is external buzzer for NMEA2000 / SeaTalk-NG Alarms.

See Canboat project for PGN details and alarm types (LOOKUP_SEATALK_ALARM_ID and PGN 65288): https://github.com/canboat/canboat/blob/master/analyzer/pgn.h

Currently PGN 65288 alarms are supported. Other NMEA2000 alarms can be integrated if required (e.g engine related).

An external Buzzer have to be connected.

The wanted alarms have to be defined in the table within the code:

struct Seatalk_Alarm Seatalk_Alarm_table[] = {

{ 1, 0 }, // Shallow depth

{ 5, 0 }, // Off Course

{ 14, 0 }, // WP Arrival

{ 20, 0 }, // Pilot Off Course

{ 21, 0 }, // Pilot Wind Shift

{ 22, 0 }, // Pilot Low Battery

{ 29, 0 }, // Pilot Way Point Advance

{ 37, 0 }, // GPS Failure

{ 38, 0 }, // MOB

{ 104, 0 }, // AIS Dangerous Target

};

Just change/add/delete alarms as wanted with the Alarm ID from LOOKUP_SEATALK_ALARM_ID

The code is using the NMEA 2000 libraries from Timo Lappalainen (https://github.com/ttlappalainen).
