I think i got some thoughts how to connect to it.
But the problem is that the controller only has an 5v out/input. where as the interface want a 3.3v.

from this site, i got the pinout. http://www.pedelecs.co.uk/forum/threads/...449/page-3
It is the same controller, but the user asking do not have an lcd like us.
I will try to connect it up in this weekend.

V0 is 5v
GND is 0v
12V is 12V.
H1, H2 and H3 are the hall signals.
VIN is battery voltage
VKEY is the return from the switch that powers the controller with battery voltage
I need to know which ones the throttle, PAS, brakes, and control panel are connected to.
I'm guessing DBK is the brake signal and DVP is PAS

If any, DSM looks like the best candidate: Data - Speed Modulation maybe.
