I expect you have found my NMEA 2000 library and its available documents on GitHub.Library example ActisenseReader connects Arduino to the NMEA2000 bus and send data to Serial (USB) in Actisense format. Actisense format is still just NMEA 2000 meassages packet to single packages, which has to be parsed and requires knowledge of NMEA 2000 data structure. Instead you can take a look to example DataDisplay2, which reads as sample several different messages and sends them parsed to clear format. You should be able to modify example for your needs and send data in format you prefer.Also take a look to http://signalk.org/ example ActisenseReader provides data in format, which is readable by SignalK. I have not checked, what platform they support. At least with RasberryPi and example ActisenseReader (or Actisense NGT-1) you can build up SignalK server, which provides data for HTML browsers.
NMEA 2000 also requires that device has to be isolated from the bus, so if you have any other connection from your device, you should use isolated tranceiver and isolated power on bus side. On own boat, where you have all power lines anyway connected together, this is not so big thing, but you have to remember that other devices may be totally isolated, so you get fancy problems ifyou mix connections with them.
