Greetings from Spain
Hello everybody, forgive my English "Englipotato" smhair.gif

    While it's not a library for the DS1820, there is a library for 1-wire communications here: http://obex.parallax.com/objects/18/·

    I think the only dallas semiconductor temperature sensor there is a library for is the DS1620 which is an SPI based chip. It appears that the output of the DS1820 is the same as the DS1620 if your right shift the output of DS1620 right by three bits, so you should be able to use it as a template to create a library for the DS1820.

    It is a pity to use 3 wire control DS1620
    Investigare on DS1820
    If I make a library, I would like to share with everyone.
    I have 1 library for a LCD 20x4. I do not think that anyone wants.
    It is a lcd only sold in spain
    It is specifically for microcontroller which handles LCD "LCD SYM20AA"
    If someone needs it.
    I will give

    I speak like Indians in the movies!
    Horrible

    Sorry· confused.gif
