ADC_DMA Implementation in S32K144

[sarwath]

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

Hello @sarwath,

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

Hello @danielmartynek ,

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

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

https://www.nxp.com/docs/en/application-note/AN5258.pdf

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

You can refer to

AN4765 MPC57xx Configuring and Using the eDMA Controller

https://www.nxp.com/docs/en/application-note/AN4765.pdf
