I hade some success with the reverse.
Now there is full power going backwards too, but thats just thrilling
Not quite ready for public release yet, but soon.
I made a small adapter that connects to the ICSP.
Thats because in the newest source code it looked like all other pins are in use.
The negative side of that is that you can no longer debug the code.
I took the LED output and had it show when the reverse is enabled or not.
So you can see that it will not let it change into reverse unless it is rotating really slow.
In the video the throttle is setup with clockwise=accelerate, anticlockwise=regen.
