How to implement lpadc_edma example in the FRDM-MCXA156?

[AlexWang2025]

Hello, NXP Support Team

I want to implement lpadc_edma example on the FRDM-MCXA156. Similarly, I found lpadc_edma example in the FRDM-MCXN947 from SDK_25_03_00. But FRDM-MCXA156 don't have this example. I want to implement this funciton on MCXA156. Try, But failed. My question is does the MCXA156 can implement this function?  If it can be, please give an example based MCXA156. Thanks!

Anyway, it works on MCXA156. It shared my project named "lptmr_lpadc_edma". Hope this can help some one else.

Hi @AlexWang2025 

Unfortunately, we currently do not support lpadc_edma example on the FRDM-MCXA156.

But the edma of MCXA156 and MCXN947 is the same.

So i think you can refer to the lpadc_edma example in the FRDM-MCXN947.

I will report this requirement to our SDK team.

Hi, @Harry_Zhang 

Thanks for your reply. I not familiar with the MCXA156. It's pretty new for me. I just want assess this board as soon as possible, and make a preliminary assessment of whether this chip can be used in our project.  As the adc sampling through the dma way is very important function in our application. As far as I know, the edma of MCXA156 and MCXN947 is not the same. As least, from the SDK side. As you mentioned, you'll report this requirement to NXP SDK team. Please go ahead. And by the way, please add more examples of edma3,  not just in the kEDMA_MemoryToMemory way. OK, anyway, Thanks for your reply!
