NI1000_LuS_TO_INT: INT

NI1000_LuS_TO_INT: INT 1:

This function calculates a temperature from the value of an NI1000 L&S resistor.

Connect this function to iMP_Sensor_Analog. As output, you receive an INT variable that represents the temperature with a resolution of 0.01°C (20.5°C, for example, is represented as 2050).

The lowest valid value of 872 ohms corresponds to -30°C. If the value is smaller than this, 16#7FFD is output.

The largest valid value of 1586 ohms corresponds to 115°C. If the value is greater than this, 16#7FFE is output.
