    rotary encoder absolute, serial manchester

       Good afternoon, I am Colombian, I dont have good English, I hope  you understand


      I will comment that my project is to know how I can help.




      I have two rotary encoder, they send the absolute position by a frame of serial data by a Manchester code, the encoders are of 11 bits.




      To get the position, I decode the signal. The Manchester decoder is not the problem, the problem is the timing, and for that I get a interrup for rising edge  and falling edge  to synchronize the decoder.


      The delivery code encoder is shown in Figure




      I must get the data (15 bits) of the first frame.


      I do not know what idea you have to be able to help.




      Attached two codes


      One simulates the clock and then with a interrup on and off an output pin.


      The other has a signal input to the decoder.




      none works.
