Nios2 isnt needed but it's recommended

You probably need a DMA to transfer the data

Cyclone is the low-cost FPGA and it should fufill your needs

Many thanks

Cyclone starter kit on the way!

Could you explain why the Nios2 isnt needed but recommended? would it just be a lot simpler to achieve my goal goind down thew Nios core route?

So i have setup a

A Uart

SPI_Slave_To_Avalon_Master

onchip_memory

onchip_fifo

and DMA

So i guess a little code in the Nios core to check if anything is in the fifo, if there is, then move it to the SPI memory mapped area

or

Use the Nios2 to setup the DMA to automatically move that data?

Does anyone know of any examples i could study for this?

Many thanks
