Thats the thing I' like to control. My approach to decode is "look for
Edges" in the signal
and messure the distance between. Would have been nice to see how somebody
else
has done this. Hope to have my Code detecting Pakets in abt. 1-2 Weeks.

Has somebody written a PIC-based backemf regulated  PWM controller for
DC-Motors or Suggestions how to do ?

Best regards
