topic ADC conversion issue in S32 Design Studio https://community.nxp.com/t5/S32-Design-Studio/ADC-conversion-issue/m-p/1170274#M7868 <P>Hello Team,</P><P>I am working on ADC driver with S32K146 controller for Autosar platform. I am using Tresos tool(S32K14X_MCAL4_3_RTM_HF2_1_0_1<BR />NXP driver stack) for code generation. I have done the below configuration:<BR />Adc HwUnit0: one Adc group with 5 channels, ADC SW trigger, back toback mode enable, one shot trigger conversion without interrupts<BR />Adc HwUnit0: one Adc group with 1 channel, ADC SW trigger, one shot trigger conversion without interrupts<BR />With this configuration I am able to get the correct conversion data (verified with different voltage inputs) in HW<BR />register but I am not able to read the data in user buffer using ADC_ReadGroup API. I am getting ADC status as ADC busy as the coversion flag is not set after conversion.<BR />So as per my understanding conversion flag should get set as soon as conversion is completed. Can you help me to understand this behaviour or I am missing out any configuration?<BR />If any other configuration details are needed please revert me.</P> Tue, 20 Oct 2020 10:02:43 GMT shudhamatinarha 2020-10-20T10:02:43Z ADC conversion issue https://community.nxp.com/t5/S32-Design-Studio/ADC-conversion-issue/m-p/1170274#M7868 <P>Hello Team,</P><P>I am working on ADC driver with S32K146 controller for Autosar platform.
