As default NMEA 2000 library will have all NMEA 2000 mandatory features automatically enabled.
|
|
Some rarely used or new requirements takes so much memory, that you may want to leave
|
|
them away. Arduino IDE does not have possibility to define compiler definitions on
|
|
project, so here is sample file, where you can disable some features and save memory.
|
|
Note that YOU SHOULD NEWER UPDATE this file to the library with definitions enabled! If
|
|
you want to change any definitions inside, copy this file under you libraries to e.g.
|
|
path NMEA2000_my and remove it from downloaded NMEA2000 library path.
