Now that I've got it running, I think I see how it works. However, I'm assuming this uses a circuit that has 5vreg to a bias R (default 2200 ohms) then to Rth then to gnd. The A/D reading is between GND and in between Rth and Rbias.
yep, sounds about right, 2200 is the NipponDenso jap standard.

This program creates a look up table for use with FreeEMS (or perhaps other) that could be downloaded to the EMS and used to calibrate the data that comes out.
No, it produces a C file to compile into FreeEMS but some minor extensions could generate a file to load via FreeEMS-Tuner once we finish the work around those formats etc.

Now that we have serial comms working (or mostly working), perhaps we should set the next mile marker as getting the log message to produce a reading from the temp sensor.
I've already got messages like taht, but with the ascii logging...
I'm working hard to get your specs and aarons specs so we can all work in parallel. It all takes time though.

So some future enhancements might include a little schematic drawing, showing the hip bone connected to the leg bone
Good idea :-) Shameem ? Only if you are bored... :-)

using more than three data points to create the lookup table
Not required, the spreadsheet in /doc/ can help you tune it to your data before generating the compilable file.
