hi:

thanks for your reply!~

I have added the .h files in niosii software,and I writed :

IORD_ALTERA_AVALON_PIO_DATA(BASE_ADDRESS_OF_SLAVE);

fogive me making some writing mistakes!~~

Coulde I ask you a quesion:

!: the data writen into FIFO ,how to make sure their address in SOPC memory map?the system,h only can tell us the SOPC component base address.so I donnot know how to use slave_address,and let if point to FIFO data's address(I am sorry that building custom SOPC conponent is still somekind hard for me~)

best regards~
