I'm trying to communicate to a DS1820 via a DS2480. But it is still,a bit confusing to me, when to switch to Data-Mode or Command-Mode,and when to send Reset-Codes and so on. As this is my first 'contact',with the "1-wire-world", I would really appreciate a little help, some sample-code showing how to read the temperature from the DS1820 (via,a DS2480 !) would help a lot. Or even a something like: Write E1 read .. Write ... Write ... read ... (should have the value ....) etc. regards, Reelf -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
