Be careful with this driver. I use it in a project (3 DS1820 on 
different pins), and I must use old avr-gcc (Winavr 20030113), because 
this driver doesn't work with the later versions, however I can compile 
and build without errors.
I read somewhere about different handling of inline assembly code in 
newer avrgcc, so perhaps it causes this problem. Does anybody here, who 
can help to solve this problem? I tried to send email to the author of 
the driver, but his address is dead.
Here you can find a scope image to compare the results of avrgcc and 
codevision code for DS1820, and the avrgcc test code:

This driver package seems great work, so it would be fine to use.
