I have just ordered some samples of the Dallas Semiconductor DS1820 temperature sensor with a one-wire interface. I would like help with the DS1820 protocol. I would appreciate any code snippets, especially for the 16C84 or for a PC parallel port. Assembler, C, or Basic will be fine. Thanks in advance Gus -- Gus Calabrese Lola Montes WFT Electronics 4337 Raleigh Street Denver, CO 80212 303 964-9670......voicemail mailto:wft@frii.com http://www.frii.com/~wft Alternate: 791 High Street Estes Park, CO 80517 if no success with wft@frii.com, try .... mailto:wft@bigfoot.com then mailto:wft@eudoramail.com
