A few things.

Correct.

Forward is 'normal' so that a faulty switch does not reverse the car while driving down the interstate at 70 mph.

EVTV has described that the Tesla needs the brake engaged and the speed within a few rpm of 0 before you can change from Park to Drive, Drive to Reverse, Reverse to Park, etc.

Maybe 1 extra input for the brake? It would be tied high, Active low, grounded by the switch.

How about just running the source ground through the brake switch before going to the reverse switch?


Yup - I think so.



One LED lit to show high (normal) and one to show low (reverse)?

I wasn't goingto worry about the led since I'm building a race car and going to simple, but would be easy to implement with another wire.


I have no experience with the code - I will need to look through it eventually. But I'm not much help right now.

Same here
