I'm involved in a project where we're converting a diesel boat to electric. All the electronics and the motor work on the bench, no questions there. My main task in this is getting the data about the rpm, power and everything else from the Curtis 1236 controller, into a raspberry pi. I'm having trouble where to start. What pins on the controller and pi should connect, is something between necessary, what software do I need? Say I want to log the rpm to a file every second, as a start. Thanks!
