You can take ADC readings with the thermistor at several different temperatures to calibrate the system, scale the readings to degrees F for display, then use interpolation to determine/display other temperatures.
I am unsure how to do that in code. If I have a resistance scale can't I figure the result?
The simplest is a voltage reference, a fixed resistor and the thermister to ground selected so your A/D has a good range and meets resolution requirements.min and max temperature. It may not meet one and you;ll have to change your method.
Okay... Are you doing C or ASM?
If C then you can just look through my articles... Most of which will be applicable to your application... Anything that isn't there. Just ask??
To really help the TS/OP you could give a specific link or just name those WAY more accurate.Why would anyone want to use a thermistor for anything but crude min/max limits? There are other easier, inexpensive, and WAY more accurate (repeatable, reliable, and precise) ways to measure temperature!
