Hi Al,
I'm working on digital compass project and I have selected Butterfly STM32L board from here:
https://www.tindie.com/products/TleraCorp/butterfly-stm32l433-development-board/
the compass is tilt compensated output of yaw, pitch, roll and ROT. It will have NMEA0183, NMEA200, and sine/cosine analog outputs simultaneously.
I got everything running on Teensy3.2, but i need the 2 DAC outputs from the butterfly board for sine/cosine output.
I was wondering if this Butterfly STM32L architecture could be easily supported?
thank you!

Thank you very much for this library (and your others). I have put together a test and am having a small problem. I am an ATMega64M1 and have tested 2551 and 2562 transceivers. Both work initially then freeze after a few seconds. If the board is disconnected from the bus, it doesn't freeze. If I switch off the Garmin chartplotter off it doesn't freeze. The Garmin outputs a few messages, my theory is that this is causing the problem.

Do you think 4kb is enough memory? Should I be applying some of the strategies to reduce memory usage mentioned in the NMEA 2000 docs?

I have done some limited testing with this library on AT90CAN128 w. NMEA2000_avr library, however I did not succeed in getting it to run (seems to stop the program at NMEA2000.Open)

As an alternative, I have gotten it to run by substituting in AST_AVR from https://github.com/Atlantis-Specialist-Technologies/AST_CAN_Arduino_Library.

Hope this info is helpful for future development :)
