NMEA0183

NMEA0183 library for Arduino, Teensy and RPi

Object oriented NMEA0183 library for Arduino, Teensy and RPi

Library gives you a e.g. easy way to make NMEA0183->NMEA2000 interface like Actisense device.

Currently there are most common NMEA0183 messages parser/create function.

To compile example NMEA0183ToN2k or NMEA2000ToNMEA0183 you need also NMEA2000 library https://github.com/ttlappalainen/NMEA2000 and board dependent driver libraries. See more on NMEA2000 library document.

Note for Arduino DUE users!

Currently code uses availableForWrite on writing serial. You have to modify next files and add availableForWrite to them. Note also that paths are version depended and here 1.6.11.

"C:\Users\AppData\Local\Arduino15\packages\arduino\hardware\sam\1.6.11\cores\arduino\Print.h"

virtual size_t write(uint8_t) = 0;
virtual int availableForWrite(void) = 0;
size_t write(const char *str) {

"C:\Users\lappalai\AppData\Local\Arduino15\packages\arduino\hardware\sam\1.6.11\cores\arduino\HardwareSerial.h"

virtual operator bool() = 0;
virtual int availableForWrite(void)=0;

== Changes ==

• Changed tNMEA0183Msg::AddLatitudeField and tNMEA0183Msg::AddLongitudeField to add leading zeros as default.

09.02.2024

• Changed GSV parsing to accept at minimun just one satellite without rest fields.

• Updated copyright year.

20.05.2023

• Added NMEA0183SetRMC possibility to use FAA mode indicator and nav status.

• Added AddStrField to NMEA0183Msg module.

• Updated copyright year.

• Below thanks to Andrei Errapart

• Added #include to compile with MSVC

• Changed include #include "NMEA0183Msg.h" to double colons on NMEA0183Messages.h

• NMEA0183SetSHR: New function to format pitch, roll, heave and heading in RT300 format.

• Fixed NMEA0183ParseAPB_nc APB.xte *= nmTom;

• NMEA0183SetDPT: added optional parameter DepthFormat to allow higher resolution on message.

• Added first unit tests for SetDPT/ParseDPT

• Added SetZDA.

07.04.2022

• Fixed use of breaktime on NMEA0183Messages.cpp to tNMEA0183Msg::breakTime and added inline bool NMEA0183IsTimeNA(time_t v) to NMEA0183Msgs.h. Thanks to debbia.

23.02.2022

• Added _FieldCount checking to NMEA0183Msg.cpp tNMEA0183Msg::SetMessage. Thanks to Andreas Vogel.

• Updated changes to GitHub. Several changes has been in use on own code, which were not published. E.g., NMEA0183GetDouble has been changed to replace atof.

• Updated copyright.

15.02.2022

• Add parser for DPT by mjsneijders.

21.08.2021

• Thanks to sailingfree. Added GSV parser.

• Thanks to orca-hydromancer. Accepts lowercase hex in checksum.

• Changed some value parsers to use NMEA0183GetDouble instead of directly atof.

• Fixed month handling in case of TimeLib.h has been used. On tmElements_t month starts from 1.

• Empty values returns now NA.

• Added GetMessageStream for tNMEA0183.

08.04.2021

• Thanks to lsoltero. Fixed logic error on NMEA0183Msg.cpp tNMEA0183Msg::Init "if ( _Sender==0 &&..." -> "if ( _Sender==0 ||...".

• Added Status for ParseRMC.

• Thanks to BerndCirotzki, issue #22. Added missing iBuf++ to tNMEA0183::SendBuf.

• Added Changes to README.
