I've interfaced a VN-100 using a UART with a different processor, not a

good ANSI C reference driver along with math libraries and so on-- check the
bottom of  and the "Embedded Firmware Library User Manual" at . There
are some blanks to fill in in the code, but the documentation is actually
pretty good. It was too long ago for me to remember many details, but there
you have it.
As long as you have your UART or SPI bus working (and with the appropriate
level shifters), you should be all set.
