ADC_DMA Implementation in S32K144

Hello Community,

I am triggering the ADC by PDB and output I am reading by polling method instead of interrupt.

Now I want to replace the polling method by eDMA.

How to configure the DMA to collect all ADC results.

Thanks,

Sarwath

You can find some ADC PDB DMA examples in this list.

Is there any document (like AN12217) to read about the DMA implementation.

For the S32K1xx series, there is this application note only:

But the eDMA module is very similar to the one in MPC57xx.

You can refer to

AN4765 MPC57xx Configuring and Using the eDMA Controller
