the Kinetis SDK includes a FlexCAN EDMA driver for RX FIFO. It seems it triggers an interrupt each time a frame is transferred from the head of the FIFO into memory via DMA. I don't see the advantage here? Isn't it the same as just triggering the FlexCAN interrupt on the RX FIFO when a frame is ready????
Is it possible to transfer more then one frame with one DMA request?
Is it possible to transfer multiple frames from a FlexCAN mailbox via eDMA?
Thank you for any response.
