How to turn off the ADC interrupt?

durga_choudhury — Mon, 13 Apr 2026 18:57:19 GMT

MCU: S32K148

Driver model: Non-autosar

RTD version: 3.0.0

I want to do a blocking, software triggered read from the ADCs. One thing I could do is to pass a NULL_PTR as the 'Conversion Complete Notification' (this has the unwanted side effect that the generated code generates this as &NULL_PTR; I have already reported this on a separate thread).

However, I don't see any means, via the peripherals GUI, to disable ADC ISRs altogether. In other words, I want the code generator to generate

#define ADC_IP_AIEN_INTERRUPT_ENABLE (STD_OFF)

in Adc_Ip_CfgDefines.h

How can I do that?

Hi @durga_choudhury,

In order to disable interrupts, you must disable the 'Adc Normal Interrupt Enable' option within 'AdcHwConfiguration' container, and check the 'Adc Group Without Interrupts' config under the group configurations array:

This generates the ADC_IP_AIEN_INTERRUPT_ENABLE define as STD_OFF:

Best regards,
Julián

Hello @Julián_AragónM

Thanks for the response, but I am not using the Autosar driver model. My peripheral configuration looks like this:

In this model I don't see an equivalent of what you show for the Autosar model.
