i.MXRT1170-EVK LPUART idle line interrupt with EDMA

[igrinberg]

Hi,

I would like to use the LPUART of the EVK board to receive messages of unknown size.

For this purpose, I would like to combine the usage of idle line interrupt and the eDMA mechanism.

The examples found in the SDK are with IRQ separately and eDMA separately, how can I combine the two?

Is there a relevant example code?

Thanks,
Ira.

Hello

You can use the example "lpuart_edma_rb_transfer" from the RT10xx SDKs as a reference for Idle Line Detection.

If you have more questions do not hesitate to ask me.
Best regards,
Omar
