I have too many uart data to receive, and the frame length is not sure, and I do not want so many uart interrupt, so I need timeout receive data+DMA, could NXP give me a demo, thank you very much!

 

my tool is S32SDK3.0 + S32DS2.2

Hello,

 

There are two available examples which can be useful for you:

After opening S32 Design Studio, go to File -> New S32DS Project From, and there can be found edma_transfer_s32k14x. The purpose of this driver example is to show you how to use the eDMA. 

Or you can look at the attached a very simple LPUART TXRX DMA example for the S32K144.

 

I hope it helps.

Best regards,

Diana
