S32K144: SDK LPUART idle line interrupt support

Question asked by Joao Roscoe on May 14, 2019

As far as I could understand, both S32SDK_S32K1xx_RTM_3.0.0 and S32SDK_S32K14x_RTM_2.0.0 won't support the idle line interrupt - LPUART_INT_IDLE_LINE.

 

Is that correct?

 

I need to deal with Rx frames with lengths I don't know in advance. So far, I'm doing that by passing a large Rx buffer and by pooling it's content until I find a complete, consistent frame. It works, but a pure interrupt solution would be cleaner and faster.

 

What would it take to add LPUART_INT_IDLE_LINE support? Any plans to add it?

 

Best regards,

Joao
