Hello,thank you for replying.

I make a project ,using vhdl code.I found an ALTERA code for SDR SDRAM controller, and I try to write into DE2 SDRAM, data from camera of 640*480 resolution, each pixel is 16 bits.

My question is in vich order and vich commands to use , in order to write data to SDRAM.I don't know, if I should give the adresses,or they promote automaticly.

I'l apreciate if YOU could send me an example of the orders for writung this data length and/or some explanation.

Thank YOU,

Roman.
