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.
