[Ovmsdev] OVMS Leaf Support

[Mark Webb-Johnson]

I think the leaf spy app shows what can be done. It only uses standard OBDII, with just one can bus. It could also be using the other non-can OBDII buses, but I doubt it.

Shame it is not open source, but the leaf codes are pretty well documented now.

Regards, Mark

If you use MAC OSX, the development environment is simple to setup - for windows there are a few more hoops to jump through. Lastly, a RS232-USB adaptor is useful (but not essential).
