How to make working one HCTL2016 and a PIC16F876

Hi to everyone! I am a newbie at PIC16F876 and i have a project to make(that's why i am not swimming at a beach now!snif,snif)

The problem is the following:
I have an incremental encoder (AGI HEDL-5540 A11) connected with a motor (maxon).And i want to take the pulses that the encoder sends and save it as a number in the PIC16F876. Somebody told me that HCTL2016
makes that.Reading the manual i made the right connections but i am stuck with the code in PIC that is required.Every pin like PORTB.0,PORTB.1..... have 0 or 1 as i understood.But iam save it as a whole number in 1 register!And the manual says that HCTL2016 is 16-bit.So must it the number of a position be send in two cycles?Please help me!

I would really really...appreciate if you could give me some bit of code to understand.Thanks anyway in advance

mmm, can you tell more about what you want to do with the rotary encoder???

i'd never use this IC and i believe we can remove it and connect the encoder directly to the PIC.

I often use rotary encoder in my apps to navigate between menu and/or get user entry. So an extra IC should be motivated by something that i don't see/understand.

Bellow is one example to use rotary encode to increment/decrement a variable

Code:

---

    ' Procedure to get value change from rotary encoder
    '
    OldPos = (PORTB & %11000000)>>6 ' get only PORTB<7:6> bits
    NewPos = OldPos
   
    ' see if encoder has move
    '
    while ((NewPos==0) or (NewPos==3))
      NewPos = (PORTB & %11000000)>>6 ' get only PORTB<7:6> bits
      wend
   
    pause 20 ' debounce delay
 
    ' Get encoder movement
    ' --------------------
    '
    '      Rotary encoder output table (clockWise rotation):
    '      -------------------------------------------------
    '            00
    '            01 between move (half detent)
    '            11
    '            10 between move (half detent)
    '
    '    Using XOR
    '
    '              OldPOS  : 0    0    3    3
    '              NewPos  : 1    2    1    2
    '              movement : CW  CCW  CCW    CW
    '          XOR -------------------------------
    '                          1    2    2    1
    '
    ' So, if NewPos XOR OldPos = 1 => increment
    '        Newpos XOR OldPos = 2 => Decrement   
    '
    Newpos=newpos ^ oldpos
    select case newpos

          case 1
              menuchoice=menuchoice+1

          case 2
              menuchoice=menuchoice-1

    end select

Thanks for answering.I don't want nothing extreme.Just to have a number in PIC16F876(for example 16 degrees or 352.16 degrees,something like that) how many degrees the motor turned. The concept is to make a PD controller.But in order to make the PD controller i must subtract the desire degrees of rotating the motor (turn 5 degrees) with the actual.And i want to control the actual degree.The first i made it with a SERIN2.They said to me that the encoder gives pulses and in order to make them 0 or 1 i must have the HCTL.Is that wrong?

i really didn't understand much from your code (f.e what is >>6).Can you be please more specific?Sorry but i am now beginning....

hawk,

I'm sorry I have to say this,
but how about having a look at your chips datasheets and the PBP Manual?

i.e.
"<<" and ">>" are described in Section 4.17.3 of the Manual
