Take a look at http://www.circellar.com, they have an article on there
that is computing acceleration data from a model rocket.  They use that
xicor chip X25F128 and the pic's spi port.  it's a very cool idea, I'm
not sure if it works, but you might be able to extract some info from
the accompanying code for help with your SPI port problems....

luck for everyone,
Jon
