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_mV

voltage read from the multiplexer in mV

Returns

temperature value in deci °C
