Honored ContributorI 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
Honored ContributorI 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 ...

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)Honored Contributor
