Hi Croman13n3c,

I see what you are referring to in the note.  I think I found the link to the source code for the thermocouple, so please download it at this link.

The source code for this circuit note has been modified - you may download the latest from the same link specified earlier.

With the latest version, functions are available that use the ADC measurement value to calculate the thermocouple temperature reading as well as the theoretical best values returned by the algorithm.

In the coming days, we will add extra information to CN-0214 also.

Using the latest source code, we see a worst case error of better than 1C when the ADuC7060 ADC samples the T-type thermocouple.

Just to clarify, the function that calculates the theoretical best values returned by the algorithm was not included in the released source code.

This was a simple function that took an array of voltages and passed the values from it to the temperature function.
