Yeah getting the table isn't hard I can get one online or if I buy good name brand thermistors I can get it from the mfg, I just don't want to figure out how to program it to use the table.

I'm using an NTC thermistor instead of an RTD because they are cheaper and the resistance changes more significantly so you don't need a separate amplifier chip. Ultimately you only get 1023 bits from the analog input and they are spaced evenly from 0-3.3v so the challenge is getting your dv/dtemp as large as possible in the effective range you want to measure. If you want to push the range all the way out to the max of 300c that means you will have fairly poor resolution at room temp, which is fne just kinda annoying when it's jumping 20 degrees just sitting there. There are a couple tricks I can use to smooth the data, and I've also heard to use a filter cap on the circuit although that's more components I would like to avoid.
