Hello David,

Did you already use that library ( http://www.mikrocontroller.net/attachment/53861/NMEA2000ToNMEA183.rar )?
If yes, what hardware are you using? I have an Arduino UNO + Sparkfun Can-Bus ( http://www.sparkfun.com/products/10039 ).
I want to send some data over NMEA2000 bus to all node (broadcast).
I'd like to have a code example to send data using that library (if possible) or a brief guide to using the library.

Thanks a lot

I also have an N2K project I need to work on, but the expense of the protocol and certification is holding me up. Have you had any luck so far?

I have just started with embedded programming but been writing enterprise software for many years.

I have just pulled together a base NMEA 2000 / J1939 protocol stack. Currently I have support for a limited number of PGNs but I do have  support for single and fast frame NMEA2000 messages. The current project is to create NMEA 2000 transducer that will read analog engine data and broadcast PGNs 127488 (engine Rapid), 127489 (engine dynamic), 127505 (fuel level). The protocol stack is built to quick add additional PGNs with minimal amount of code.

 Also I'm finishing up support for address claim and other NMEA 2000 group functions. If you are interested in working with me on adding additional capabilities and functions let me know. The current implementation runs on Arduino Uno with Sparkfun CAN-bus that uses MCP2515 CAN controller.

Hi, @southern_cross: I'm most interested in your work. Myself looking at the possibilities to use Arduino + shield to prototype a marine monitoring interface. Basically I would want to monitor and convert to NMEA2000 the engine data you mention plus some additional ones, like PGN 127508 - Battery Status. Possibly also some environmental data and in future also read and parse the AIS PGNs. I've previously only been working in the NMEA0183 domain though now believe that the transition to 2000 is inevitable. If you are willing to share your progress and also specify how you would want to co-operate I'd be very happy to join.

Hi, I'm new to this forum.  Just wondering if there has been anything more on the subject of interfacing Arduino and NMEA2000?

BTW, there is an open-source NMEA 2000 decoder project over at https://github.com/canboat that looks useful.
