DS18B20 Question

[ozarkshermit]

Sorry - I should have added that I am using 9 bit resolution . Things work fine using 12 bit.

I use 9 bit since the conversion time is 93.75 ms, compared to 750 ms for 12 bit. At least, that is according to the data sheet that I have for the DS18B20. I do not want the program waiting 750 ms to convert.

I guess it will be best just to close this thread. I will come up with some kind of work-around.

Problem Solved - -
The problem was in my code - - As I mentioned, I have the DS18B20 configured for 9 bit resolution.

In my code, I sent the command $CC, $44 to do the Temperature conversion, AND THEN sent the 9 Bit configuration command.

By placing the Configuration command BEFORE the temperature conversion command, it works just fine.
