Hi ,
I have problems with interfacing DS1820 to LPC2368. i can see only "127" on display. Thnks.

    You can't choose the communication frequency for the DS1820. You can choose how long to pause between each bit (infinity is ok as long as the device stays powered), but the bit timing for the communication is dictated by the datasheet. It isn't like I2C where you configure a baudrate, and then clock the data synchronously.
