In the standard SPI peripheral supplied by Altera, the shift direction and clock polarity/phase are fixed when you run SOPC builder. You would need a different SPI peripheral to do what you are looking for.

hi,

i have a bunch of different spi slaves on my bus.

each of these have a different set of likings.

i have yet to find any way to control the following at run time:

-- shift direction

-- data polarity

and so on.

any of you guys know if this is possible, or is it hardcoded when the cpu is generated?

thanks,

agdepus
