Function Documentation
◆ P5FromADC()
| double P5FromADC | ( | uint16_t | val | ) |
Converts a P5-Raw ADC Value to Voltage.
- Parameters
-
val The ADC Value
- Returns
- The Voltage
◆ P12FromADC()
| double P12FromADC | ( | uint16_t | val | ) |
Converts a Unreg-Raw ADC Value to Voltage.
- Parameters
-
val The ADC Value
- Returns
- The Voltage
◆ TempFromADC()
| double TempFromADC | ( | void | ) |
Converts the ADC-Temp of the Display NTC Value to Celsius This function also calculates the derating factor.
- Note
- This function takes extensive floating point operations and may thus block for about 400us.
- Returns
- The Temperature in Celsius
◆ HSTempFromADC()
| double HSTempFromADC | ( | void | ) |
Converts the ADC-Temp Value of the Heat Sink NTC to Celsius.
- Note
- This function takes extensive floating point operations and may thus block for about 400us.
- Returns
- The Temperature in Celsius
◆ RNTCfromTemp()
| double RNTCfromTemp | ( | double | t | ) |
Computes the NTC-Resistance for a given Temperature.
- Note
- This function takes extensive floating point operations and may thus block for about 4ms.
- Returns
- The Resistance in Ohms
◆ ADCfromTemp()
| uint16_t ADCfromTemp | ( | double | temp | ) |
Computes the ADC-Value for a given Temperature.
- Note
- This function takes extensive floating point operations and may thus block for about 4ms (mostly spent in RNTCfromTemp()).
- Returns
- The Temperature in Celsius
