ds18s20 reads incorectly

[skimask]

i have tried several programs on this and several other sites to read temperature
read a lot of posts on the subject and have been able to get most to function
however the temperature readings are all low aprox 30 deg f this is only happening when i use pbp
tried mikro and works perferct what the difference??

What's the difference? Plenty...signed vs un-signed integers is a good possibility for one thing...
We might be able to help you out a bunch better if you were to post one of those 'several' programs from one of those 'several' sites...
