Function Documentation

◆ LTC_ConvertMuxVoltagesToTemperatures()

int16_t LTC_ConvertMuxVoltagesToTemperatures ( uint16_t  adcVoltage_mV)

converts a raw voltage from multiplexer to a temperature value in deci °C.

The temperatures are read from NTC elements via voltage dividers. This function implements the look-up table between voltage and temperature, taking into account the NTC characteristics and the voltage divider.

Parameters
adcVoltage_mVvoltage read from the multiplexer in mV
Returns
temperature value in deci °C
