    hello it's me again

    may be i can use a byte adress and two byte value for the result, like this

    Code:
     
    DPIN    var     PORTA.0    ' I2C data pin
    CPIN    var     PORTA.1    ' I2C clock pin
    adres   var     byte       ' I2C adress
    ctrol   var     byte       ' I2C control
    B0      var     word
    B1      var     byte
    B2      var     byte
    
    
           I2CREAD DPIN,CPIN,ctrol,adres,[B1,B2]        ' Read 2 locations in a row
             B0.highbyte = B1	' Move HIGH byte of result to B0
             B0.lowbyte  = B2	' Move LOW byte of result to B0

  5. Use the PIC 16f877 or 877A instead of shift registers.
