what is Adc_TempSenseGetTemp parameter?

rlaxortn — Wed, 16 Jul 2025 02:19:18 GMT

i am using s32ds 3.6version, and RTD 4.0.0. mcu is s32k314 172pin.

Adc_TempSenseGetTemp parameter has 2 parameters in adc document.

but when i use Adc_TempSenseGetTemp function, this needs 3 parameters.

i understand that parameters are hwunitType, tempinstance, tempvaule.

but i don't understand tempinstance.

tempinstance is 49? that is channel number. or other thing?

what i input for tempinstance?

this is my adc config.

this is function.

this is document.

1. i understand hwUnitType is adcHwUnit_1, and tempVaule is for returnning variable value.

but i don't understand what i input tempinstance. channel number or other thing?

2. and i wanna use senser temp in MCU.

so what process is for using temperature sensor in mcu?

i think process is

Adc_Sar_Ip_TempSenseEnable -> Adc_Sar_Ip_TempSenseGetTemp

3. what is Adc_TempSenseCalculateTemp?

after use Adc_Sar_Ip_TempSenseGetTemp, do i have to use Adc_TempSenseCalculateTemp?

thanks to help.

Hi@rlaxortn

1.The RTD driver includes LLD and HLD, which are no-autosar and autosar compliant.

These two functions are derived from LLD and HLD respectively.

Adc_Sar_Ip_TempSenseCalculateTemp();//for lld dirver

Adc_TempSenseGetTemp ();//for hld driver

I have already provided you with a routine in your previous question.

2.yes

3.No.
a.Adc_Sar_Ip_TempSenseGetTemp() ->This function starts a normal software conversion with one-shot mode on tempsense channel and calculates the temperature on chip from the data conversion

b."Adc_TempSenseCalculateTemp()"->calculates the temperature based on given data(if read directly using ADC)

@Senlent

my question is i don't understand what i input tempinstance. channel number or other thing?

so i show you function parameter.

Hi@rlaxortn

u32AdcInstance-> The ADC instance you're using right now

u32TempInstance->0, because only have one Temp Instance

pTempSenseVal->the Calculated temperature value
