more then one ds1820

[Markdem]

Hi All, i ned to use two DS1820 temp probes, but i cant have them on the same bus. I need to know which temp i am getting without knowing the serial numbers of the device. I just need to put them on diffrent output pins. The only issue i have is i am not too sure how to do this. I need to change the #define line inside the program, depending on which reading i need. Any ideads how i can do this. the driver code i am using is the one out of the code section at http://www.ccsinfo.com/forum/viewtopic.php?t=19740&highlight=ds1820

Thanks, Mark[/code]

Hi,

This code http://www.phanderson.com/PIC/PICC/CCS_PCM/ds1820.html may be better suited to your application because it is written for multiple DS1820 sensors on separate I/O pins. I have used it many times, so I know it works!
