converts a raw voltage from ADC to a temperature value in Celsius.
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.
v_adc_V | voltage read from ADC in V |
TsensorType | sensor type, dependent on ADC used (ADC0 or ADC1) |
