Re:[Electric Boats] How we display data from Thunderstruck's Sevcon controller

That is awesome!!!

I have been doing research, unsuccessfully to do the exact same thing, because I'm not a coder. I would be happy to help if you decide to share.

So far I have all my NMEA0183 talking to my NMEA2000 equipment and vice versa, with all that data streaming to my iPad and a micro computer running OpenCPN, the motor data has been the one missing piece.

I was pretty frustrated when I figured out there was no CAN Bus to NMEA converters out and been trying to use analog sensors to NMEA for RPM and Voltages, but they aren't cheap so have not made it very far.

Wow I bet your wife is a good cook as well. Very interesting I am also keen to read the SevconGen 4 Canbus data. I have my system network set up for charging and managing my LiFePo4 battery pack using Canbus. But would also like to get data out of the controller and motor. I was thinking about adding a OBD-II automotive plug into my network and trying a ELM-USB with some free software to connect to a PC. Open CPN sounds interesting as well, let us know how it goes.

Hey, so my wife just wrote (is still tinkering with) some software to read the CAN bus data from a Sevcon Gen4 controller and display it on a PC screen or pull it into Open CPN and have it across the top of the chart plotter screen (or anywhere else). She has it display motor rpm, motor temperature, motor current, battery voltage, current power draw (in watts) and total energy used (in watt-hr).

We have initially used the rather expensive recommended CAN bus to usb converter from Digikey but there are much cheaper $20 versions which should work, we just have not bought and tested those yet. She also plans to interface through CAN to the Trojan Trillium LiFePO4 batteries if we get some of those.
