NMEA 2000 Shield

  • Using FRAM to log data.

Hello,

I thought using a memory to log some NMEA data like operating hours or some gps points for example.

So I posted a question about what would be the best solution to do so.

The answer was FRAM and since I didn´t know so much about I did some research on it and it sounds like the best solution sincee it is fast, don´t need battery to hold the data and have more write cycles then most other like sd card eeprom and so on. Also what is very important is that there is no cycle / data lost due to high or very low temperatur.

The operating hours should of course also be send on the bus after they are counted and stored so the question is when is the best moment to count and save the data?
Should be an extra board or is that so litle that it doesn´t matter and could be done on the board which generates all the engine data? (I´d like to have all engine data available on the bus so I use one Teensy3.X to do that.)

Any comments and ideas?

Regards..
