Thanks Quentin
but it still wont work
im am using 12508 pic,pin 5 for data pin 6 for clock..

1-- when i use status,c mplab gives error should this be status,0

what i want to do is to look at an 8 bit data word on pin 5  (standerd i2c
bus )
test to see if it is hi or low then, put the same value into the reg i named
temp

i used the adapted code you sent but i still cant get the same value into
temp reg
as i am sending into pin 5 off pic

it looks like my problem is that i am testing for hi,low bit then moving
temp reg to left (rlf)
this i am doing 8 times the last bit test takes me into carry bit of temp
reg
(12c508 has 8 bits in reg and carrybit)
so if first bit was logic 1 then and last bit is logic 0 the code then makes
carry bit 0
so i loose a logic 1 bit,see what i meen??

i have worked this out on paper and i think the 8 bit value left in temp reg
needs to be reversed
this is fine if first data bit is not logic 1,then i DO get the right value

i now the code i am sending to pic is fine(i wrote it for a nother project
and it works fine)

please please help its driving me mad..

thanks
