You would use SHIFTOUT because it is a serial interface not an I2C.

thnks wolwil , ive tryed this code but nothings happening,any idea how to address this ic

Code:

---

DPIN    VAR PortB.0               
CPIN    var PortB.1
STB    VAR PORTB.2             
B0      var    byte
B1      var    byte



main:
low STB
pauseus 1
b0 = $01

                       
    shiftout DPIN,CPIN,1,[$00,b0] 
    Pause 100             
    shiftout DPIN,CPIN,1,[$03,b0]
    high STB


        end

At a quick glance I believe you have to send the LSB first according to the Datasheet and you are sending the MSB first. On the bottom of page 6 it shows the LSB being the first bit being clocked in.

Try changing the mode on your shiftout to a 0 like this:

Code:

---

    shiftout DPIN,CPIN,0,[$00,b0]
