Hello all,
I'm having trouble connecting to a DS1821 one wire temperature sensor. I know it's an old style sensor, but I'd like to be able to work with it.
By 'trouble', I mean that I'm new at using the Arduino and I'm sure that I'm not doing the right thing with this sensor. I've read the DS1821.pdf datasheet from maxim, but I'm not sure how to use their instructions.
I've been able to connect to a DS18B20 successfully using the Dallas Temperature Control library from Miles Burton. The temperatures come through fine when using the DS18B20. Simply unplugging the DS18B20 and plugging in the DS1821 doesn't work, since I think the commands and/or protocols are different.
If anyone has an example of interfacing with a DS1821 successfully using the Arduino-0017 IDE that they would be willing to share with a newbie, I'd be grateful.
Thanks, Rich.
