NMEA 2000 Shield

further to above
I added the additional hardware (USB port) to my teensy, and using listenersender
sketch I have now been able to use your simulator s/w .
... as an aside - a BIG thanks for providing these tools, tutorials and great work on N2K library...

I can get data from simulator to display on MFD (axiom LH3) - all good, and have confirmed that
indeed the MFD is supporting (& displaying) PGN 127508... this question solved.

However ... whilst using the simulator and changing various parameters and viewing them using
actisense reader & on MFD Ive discovered some inconsistencies:

  1. engine load % appears incorrect?
  • for example when setting to 30% in simulator, NMEA bus displays 14% on BOTH MFD & actisense reader.
  1. engine fuel rate L/Hr
  • for example when setting 11.5L/Hr in simulator, NMEA bus displays 0.0052cu m/hr (5.2L/Hr) on actisense reader AND MFD displays 5.2L/Hr also.

the other engine parameters all appear to be OK ... the simulator values match MFD and nmea reader values.

also a couple of additional questions about simulator
3) DC status PGN 127506 - i can enable it in simulator, and see values on nmea bus reader
however it shows 246% for SOC ... and there doesnt appear any way to change this in simulator?
I assume its hard coded?
(MFD doesnt display... but this may be because it expects a value of 100% or less?)
4) Alternator voltage (engine PGN) - these are displayed on MFD and nmea reader - but i cant find anywhere to change these on simulator , once again Im assuming these are hard coded?
