Vinculum SPI interface

I just posted a Vinculum SPI driver in the Object Exchange and attached here.·
A few precautions; the current spec sheet for the VDIP1 shows the SPI clock·with the wrong polarity, data should be stable on the falling edge of the clock.· Also, the Status Register should be B0 for #TXE and B1 for #RXF.
Other than power and the I/O you must also attach /Reset from the Vinculum to the Propeller so that the Vinculum is reset each time you load in new code.· No additional hardware is required for a VDIP1 module.
