In my Nios II system I want to use Uart with DMA. Are there some tutorials or example projects about this topic.I'm using Quartus 13.0. Thanks.
It doesn't really make sense to use DMA with a UART. A DMA engine doesn't have a mechanism to stop sending and wait for characters to go out, or wait for input characters to be present before transferring data. The FIFO in a standard UART is so small that the time taken to set up a DMA transfer would be greater than the time to fill the FIFO with a sofware loop.
can u help me receiving 24 bytes with uart @2mbps speed.
i tried but it was receiving like first byte at last and last byte at first like that.
how can i overcome this problem
