I am looking for easy way to read 8 bits of data that is transmitted on 12c bus

i have tried to btfss on data and clock pins looking first for start bit then testing next 8 data bits

then putting bits info into a temp reg

Pic 12c508_

bitstart_

btfss gpio,1 ;clock high test

goto bitstart_

nop

btfss gpio,2 ;data high test

goto r_

nop

r1_

btfsc gpio,2 ;data low test

goto r1_

nop

r2_

btfsc gpio,1 ;clock low test

goto r2_

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

movlw 8 ;8 bit count reg

movwf count

testbit_

btfsc gpio,1 ;clock pin on eeprom

goto testbit_

ti_

btfss gpio,1

goto ti_

btfss gpio,2 ;data pin on eeprom

goto testbit_

bsf temp,0

rlf temp

decfsz count

goto testbit_

then reading temp reg with ice pic emulator

but it wont work i get wrong hex

any one now whats wrong??

thanks
