Hi,

I did not mean that actually, I know it only transfers data but does not know their meaning or if this comes this is to be done information. What I am trying to ask is how do I get it from SPI buffer to my memory or to NIOS (which are the two sides in my system NIOS-SPI-RAM ) and also I have an information in NIOS and I want to send it to RAM how do I do that where do I select where on the memory is data to be written.

Let me explain what I did. In Qsys I connect NIOS instruction and data master to SPI core's control port and connect SPI's conduit end a memory. I use this function in NIOS "alt_avalon_spi_command" to read or write data. What more should I do?

Thanks
