Hello,I would like to know is there any way/solution to add FIFO/buffer SPI rx data.Today, there is only register - 'RXDATA' is overridden every time. Thanks, Arthur.
Are you hoping for a FIFO implemented in hardware or software?The IP doesn't have an option to add a FIFO. However, it could be possible to add an external hardware (rtl) FIFO, to operate alongside the IP. Having said that, I'd have thought that a FIFO, implemented in software, is the recognised way to do this - assuming you're implementing a Nios core in your solution. Use the RRDY interrupt to trigger your interrupt routine and buffer the RXDATA. Cheers, Alex
