Hi, all PICers,

It may be an old question, but I have not seen any related in recent
months.  I want to read temperature to a PIC, as simple as that.

I have problem using the DS1620, a serial clocked in/out data device.
 Any one out there can help?  Also, the DS1620 is like C$20+ /each,
is there a cheaper sensor that can talk to the PIC directly?


Thanks in advance.
