Hello

Thanks, but i know this paper (Nios II Hardware Development Tutorial ) allready. This paper shows fine how to build a SOC with standard components.

But my problem is, that i have a own component topach_AvalonSlave wich a

AvalonReadSlave Base Adr:0xyyyyyyyy and AvalonWriteSlvae Base Adr: 0xzzzzzzzz

And my question is how can i write an value like int i=2 on the AvalonWriteSlave and how can i read the value from the AvalonReadSlave?

IOWR_ALTERA_AVALON_PIO_DATA(????;i);

Thanks for your help
