hello, I'm trying to establish a communication with my gumstix and a PIC18 throught the SPI bus (clk/frame/miso/mosi ports on the gumstix). I have used the code at http://docwiki.gumstix.org/Sample_code/C/SPI for the first test. But for differents reasons the PIC has to run as the master. But the code on the wiki makes the gumstix run as the master. Does any body knows how i can turn the SPi on the slave mode on the gumstix? Or can you give me some links where i could found some documentations, because the wiki is not very complete.

The link to the documentation can be found over here: <http://docswiki.gumstix.com/Basix_and_connex> You'll want to look in the pxa255 Developer's Guide in the section that talks about the NSSP. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |
