Help with 18b20 Stuck with busy bit

[Heckler]

you might take a look at this example... (located in the wiki section under projects/temperature)

http://www.picbasic.co.uk/forum/cont...r-nine-of-them

you can also search on "ds18b20" for other examples.
I would suggest you go through your code and add lots of comments to help you trouble shoot and for others to follow what you are trying to do.

Ty Heckler for the reply, but the link that you gave me my friend doesn't work. Stuck in loading... I deleted comments for posting on site i have done them properly :P :P

My problem is the presence pulse, i can't understand how it works even i have read the datasheet hundrend of times.

I do low for initialise, i do get a low and going for the converting procedure. But i never get the busy bit back, even i did it with 2 diffrent ways.

I suspect that the problem is the presence pulse but i dont know how to check it and that's why i came with a post (i also have read a couple of other threads but still no luck) .
