    I2Cread SDA,SCL,tmpcon,tmpaddr,[temperature.highbyte,temperature.lowbyte]

    Anyone used this pesky chip before?
    tekart,
    I am also trying to use the Sparkfun breakout for the TMP102, but with a PIC18F2550. Having similar problems in using the I2C bus to read a temperature from the device. Did you ever resolve your problem with the TMP102? If so, could you please share your PICBASIC code and any circuit schematic you are using with the breakout to make it work? Thanks!
