Hi,

I am using ADC-0 for 5 channels and ADC-1 for 2 channels

Initially configuring both the ADC and calibrating both the ADC using these functions

ADC_DRV_ConfigConverter() for ADC-0
ADC_DRV_AutoCalibration() for ADC-0

ADC_DRV_ConfigConverter() for ADC-1
ADC_DRV_AutoCalibration() for ADC-1

Later I am triggering(software) and configuring the ADC channels using ADC_DRV_ConfigChan function, then I am waiting for COC flag to be set and reading the ADC raw values

In this scenario I am only getting proper raw values for ADC0 not for ADC-1

Plese support

Thanks

Shruthi

Hi Shruthi,

I mentioned three examples to you in your last question. Please tell me which example are you referring to? So that I can troubleshoot the cause for you on the corresponding S32DS and SDK.

Best Regards,
Robin

Hi Robin,

The PTB0 and PTB1 pins are by default configured to ADC0 but I was configuring ADC-1 without switch configuration so there was a issue

Now resolved by configuring PTB0, PTB1 to ADC0 Thank you Robin.

Thanks
