[Ovmsdev] Twizy 45 and ovms firmware

welcome :-)

Branch "master" is the current main branch, if 
there is a beta version available in another 
branch, there will be a note on this list.

You don't need to rebuild yourself, I provide 
flashable releases in the german Twizy forum:

The Twizy 45 default settings have been provided 
by another german forum member, so I cannot check 
them myself. The values for T80 are definitely 
correct. The T45 TSMAP brake/neutral rpm values 
seem to be right, as the T45 has a higher gear 
ratio. I thought the drive rpms could be wrong, 
but as the drive map is normally flat 100% that 
normally has no effect so could have slipped 
through at Renault/SEVCON.

There is no formal roadmap, and my firmware todo 
list only contains nice2haves, most of them maybe 
not implementable. I'll write an extract later on.

What's lacking most from my point of view is Twizy 
specific support on the App. The remaining 
firmware ROM space will probably also be needed to 
implement the necessary CFG commands for the App.
