how to use the spi interface?

[Altera_Forum]

I have some problems about the writing of driver of spi interface? 

I use the nios_apex_20k200 board ,because there are no example of the spi diver  so I can't make it ,I want to know how to write the driver of it . I use it to drive a adc thank you so much !!! my email is wreadlee@hotmail.com please give me the mail

I am developing spi C code for a 24 bit serial DAC. 

 I would like to see dedicated IP for serial DACs and ADCs. Using SPI looks doable but the 24 bit stuff is a challange. I had Max+II logic in schematic form but would like to see vhdl or verilog for standard parts.  I found these files useful ...  C:\altera\kits\nios2\components\altera_avalon_spi\HAL\src\altera_avalon_spi.c C:\altera\kits\nios2\components\altera_avalon_spi\HAL\inc\altera_avalon_spi.h  C:\altera\kits\nios2\components\altera_avalon_spi\inc\altera_avalon_spi_regs.h C:\altera\kits\nios2\components\altera_avalon_spi\sdk\spi_struct.h

Standard parts like? 

 If you're talking simple stuff like muxes, shift regs, etc.... then try the templates in quartus / maxplus (that's the recommended way to implement on Altera devices)
