Hello,

         I am trying to use DMA to communicate with ASCLIN_LIN. I have some doubts and need help.

1. Can LIN DMA initializer and UART DMA initializer be shared?

2. What is the connection between DMA interrupts and LIN initialization?

3, LIN data to receive and send in the interrupt service function? If so, in a DMA interrupt or in a LIN interrupt? If not, what goes inside the interrupt service function?

Thank you very much

Is there a training file for UART DMA?
