Hello,
I am still trying to contact with the DS18B20 but I can't. I change the time slots and I check again the example of DS18S20 on page 23 (I use the DS18B20 which has the same time slots and commands with DS18S20). Please could anyone check my code or if you have a DS18B20 connected with a PIC could you check my one wire function? Thanks.

Hello , I am attaching code for reading temperature on DS1820

This one is from an rather old instrument I developed, still going.

It is in Proton Basic , I think it can help you

I just cut out the parts of code concerning DS1820, Setup routine and Reading routine along with the variables defined.
On the board , DS1820 Pin is pulled high with a 4k7 Ohm resistance.

Greetings

with a bit of input, Like reading the data sheet, and study of code posted here, he could solve the problems, only he seems to have.

Thank you for the invitation pikit2.
Just want to apologize for my English, I use Google for translation.
I would like to look my option to work with a temperature sensor on the bus. I tried to carry comments for clarity.
Currently I use my program to work on the bus up to 16 sensors, it is enough for many applications. If you're interested, I'll try to translate the comments and to the library and put it on this forum.

No problem, I would not translate comments, unless members have a problem, most users, should able to follow code.
