Hi, I want to learn How to use DMA to get ADC transformation result without ADC interrupt.
I used S32K344,
IDE is S32DS3.4 ,
RTD is S32K3 RTD AUTOSAR 4.4 VERSION 2.0.0
I am confused about how to config that.
Hope to get your help, thanks.

thanks for your help, but my RTD VERSION IS 2.0.0. I can't run the project you give.
Hi,
I added RTD200 version as well, so you can try.

Hello @PetrS ,
In your example you used 5 ADC channels but in "Adc_Sar_Ip_1" you defined only 1 channel, is that correct?
Is it not necessary to put all channels in this array?
Thanks,

Hi,
actually in this example BTCU is used to trigger conversions and command list is created with 5 commands.
DMA then reads result from BCTU data register.

Ok, I understand it,
But my question is: In "Adc_Sar_Ip_1" in the "Channel configurations array" option, don't you need to fill with the 5 channels used in your list?
Hi,
the "Channel configurations array" option is for specifying which channels will be converted during normal conversion. It configs NCMRx registers. This is not used in the example

Hmmm, I understand now! Thanks
