Hi All,

   

Attached is my Thermistor Calculator component ("myThermistor"). It calculates thermistor temperature from the resistance, similar to the Creator's stock Thermistor component. Calculated temperature returned as float-precision value with accuracy approx. 0.001 degC. Calculation speed is about 14-15x times faster than stock Thermistor component (formula-based) taking about 1100 CPU cycles.

     

The component was developed for fast TEC control, where accuracy, speed and wide temperature range were important. Attached archive contains the workspace bundle of the demo project, datasheet, screenshots and reference materials. Tested on PSoC5LP.
