I used this website before for calibrating the thermistiors.

there is a xls spread sheet for calculating the curve of the thermistors. Will the mv reading work in place of the joystick port readings ?
steinhart.xls
I am trying to find an old program i wrote that read from the joystick port and had the xls functions built in to.
