Read DS18S20

[PICante]

Hi all.

Short time ago I found this code posted by CocaColaKid “ReadDS18S20” in this thread: http://www.picbasic.co.uk/forum/show...hlight=DS18S20
Very neat I thought until I discovered that the STR function is not supported for 16FXXX, too bad. I have searched and found other pieces of code but they all seems to have a different approach to the task and I felt I could understand this code better. The PBP manual is not very helpful on OW and my question is what do I need to be change (and why) in this code to make it compile for the 16F688?

Thanks!

Double check your manual...and compare what it says to the datasheet for the 16F688.
'cause it looks to me like everybody in that other thread is using a 16Fxxxx series PIC and nobody is using an 18F.

Hi skimask!

Sorry, I’m somewhat confused here I don’t know what to believe in (of curse I believe in you!) since I also got a compilation error saying: “ERROR: Macro OWINSTR?W not found in macro file.”

Huuh?


Edit: Hey… it’s the other way around, it says 12-bits not supported! (found my glasses) :-) . Then (as usual) I must be doing something else wrong!

The latest PBP update should fix that problem.
If not, there's a thread somewhere around here relating a problem similar to that..somewhere...

Edit: Hey… it’s the other way around, it says 14-bits not supported! (found my glasses) :-) . Then (as usual) I must be doing something else wrong!

I don't know which manual you're reading.
My manual says 12-bits aren't supported using the REP and STR modifiers. I'd tend to believe that due to the stack/ram constraints of 12 bit devices.

Yes, my manual also says 12-bit. edited almost instantaneously! :-)

I have got the P250a patch installed, can’t seem to find any newer?

There's a b patch out now.
