  1. Hi SgrA, If you want to measure temp with Pt100 accurately try using TI's XTR105 chip. It gives you 4-20 mA output and you can configure it for 2 or 3 wire Pt100 configuration and other possibilities. You can than use precise resistor for converting current to voltage and sample that with ADC. That's how I done it. Read more about it here: http://www.ti.com/ww/en/industrial/sensors/rtd/design.html#XTR105
  2. Hi all, another newbie here for giveaway.
