Hi John,
My motors and controllers already have all of the sensors needed. I already have 2 Sevcon Clearview displays at the helm, but they are not sunlight viewable, and are not very water resistant. They display all the data I need, I just can't see it. My new Raymarine a97 MFD has a Digital Switching application where one can develop custom graphics with software from Empirbus. They have digital switching equipment for turning on/off switches, monitoring tank levels etc on the MFD. Stuff that I'm not interested in, but the free graphics development software is something that appears to have potential to give me why I want. I played around with the software a bit and it looks like you can manipulate/edit the standard engine related display items, such as coolant temperature to say motor temperature, etc. They have all the NMEA2000 data items for engines and electrical equipment available. It looks like you can even draw your own gauges with other programs, or use others' gauges and import. I just need to map the Gen4 CANOpen data into NMEA 2000 PGNs to link up with the display items I put on the display. I previously posted that I located CAN Open convertors that I feel might work. They are by ADFweb.com, but are about $400 each. The PiCAN sounds interesting and much cheaper, but appears to require more computer programming savvy than I have/have time to learn right now. Maybe it's easier than I realize?
I really think there is potential here for a very simple, elegant solution, without the need to add anything but a protocol converter, or 2. I'd like to learn/ hear more about this PiCAN converter option if someone can point me to some good info about how to implement.
Thanks,
Chris

John AHalf the fun of electric boating is what you can do simple. :-)What ever happened to good simple instrumentation?Most anything you want to know about your system can be done with sensors and minimal electronics. There is a lot of stuff out there for things like the Pi that are excellent building blocks. (Didn't someone on the list said you can easily read canbus with a Pi?)
Thermal sensors, rotational sensors, shunts and voltmeters can tell you most of what you need to know about your system.
